I dug up the receipts for the desktop. The processor receipt says "1 CPUA001368 AMD Phenom X4 9350E (65W) Quad Core Socket AM2+, 2.0 GHz, 512KB Cache, 1800 MHz HT, 65nm (HD93500DGHBOX)". You probably just needed the 9350E but I've given you the whole thing, just in case you need it. So the "50" in the number, tells you it isn't one with the bug in it (TLB bug?).

And a chain (which was growing fast), closed in bankruptcy as well. So if I needed something now, I'd have to shop the Internet to find it. Here's an 8450e from China, one core less than your current processor. http://www.ebay.com/itm/AMD-Phenom-X...item43b9e56e57 An 8550 from Cleveland Ohio. Three core. More power than your current CPU. Probably OK.

Don't forget to pick up a tube of thermal paste, if you don't already have some.

And the resulting zinc residue, is not uniformly distributed. I've used Zinc paste on transistor heatsinks, on home projects, where the poor performance is likely not that important. (I probably could have assembled my power transistors to heatsinks, without it.) I have a tube of AS3 I've had for a number of years, and there is still some left. Paul |

That wouldn't be the end of the world but he suggested I do this so I'd like to try doing it. Obviously, the lack of sound from the originally installed speaker is ominous. If you want to test whether the existing speaker is at fault, unplug it and swap it with the tiny, test speaker. It is only a 2-wire connection and polarity is not a concern. The indication of no sound from the speaker along with what seems to be a failure of the motherboard to go through POST and boot points to a damaged or destroyed motherboard chipset if not the CPU. *A voltage spike whilst adding the RAM to a motherboard still powered is all it takes. (When I service a computer, I cut off the power to its PSU in addition to switching it off.) Time to decide whether or not the cost of a service call is worth it. The alternative would be to consider salvaging what still works in the present system and using them in a new, upgraded system. (If there is a replacement motherboard that accepts the CPU, it should be checked.) I suspect the gizmo that the tech gave me is just such a tiny test speaker. I'm just not clear on where to connect it. I'm assuming that I need to disconnect the existing speaker first - perhaps it was fried as a result of my foolishness - but the spot where I _thought_ it should be connected doesn't seem to have anything there right now. I can only assume I am misunderstanding where it needs to go. [Pause while I plug gizmo into panel header in indicated position even though there's nothing connected there already.] Eureka! We have beeping! I'm darned if I can tell how the original speaker worked since it was apparently not connected but I clearly have a working test speaker now. Okay, I'm going to try what the tech suggested and put each memory card in each slot and note the behaviour. I'll report back here when I have the results. |

If I can't get this figured out, I'll just have to bring the computer to the tech and leave him to figure everything out. That wouldn't be the end of the world but he suggested I do this so I'd like to try doing it. If you had nothing connected to the 1x4 SPKR area of the PANEL area, it would be pretty hard for the speaker in your computer case to make a sound :-) The portable speaker you've been sold, is likely a piezoelectric type. It's a round black disc, about the size of a quarter or a dollar coin, with two electrical connections on it. For computer usage, it will have a red/black twisted pair of wires connected. And, we would hope, have a 1x4 pin spacing. (Red wire on pin 1, nothing in 2, nothing in 3, black wire on pin 4.) That would mate to your M3A SPKR pins. Now, if the piezo happens to have a 1x2 connector, that won't fit the 1x4 span of the M3A motherboard. If it was the converse (1x4 speaker wire, 1x2 type motherboard), you can move one of the pins out of the plastic shell, and move it to a different position in the shell. On the 1x4, there are tiny plastic tabs in each pin bay, that if *gently* bent outwards with a hobby knife, allow the pin and wire to be withdrawn from the shell. That's how you adapt a 1x4 piezo, for a 1x2 motherboard (such as a Dell/HP etc). Asus motherboards tend to have larger PANEL header areas, than Dell or HP systems. An Asus can be as large as 2x10, while a Dell or HP could use a 2x4 configuration, with 1x2 spacing times four wire pairs. A company making piezo speakers, isn't going to waste their time making all possible combinations of plastic shells on the end. So you can try taking a 1x4, and move one of the pins so that the span is 1x2. That's how you'd fit the 1x4 piezo, to a Dell or HP. Since your Asus uses a 1x4, that isn't necessary. Either the piezo you've been given has the right span, or it doesn't. If the piezo had a 1x2, you'd need to buy a 1x4 shell from here, and transplant onto the end of the piezo. Kinds pointless. I'd just go to the computer recycler, and get a regular magnetic speaker with 1x4 on the end, for nothing. (Example of a 1x4 shell, for home projects - make sure the pins fit, or buy a set of pins to go with it, if the existing pins don't fit. I'd just buy one of each, because the postage will be more than the goods. This is if your piezo, had a 1x2 on the end.) http://www.frontx.com/cpx075_3.html http://www.frontx.com/cpx076.html ******* 1) Connect piezo. Connect with power off. Greatest danger is bending a pin with the power on. The +5V, as far as I know, is not fuse protected. I remember someone relating a story, where they shorted the speaker +5V wire, and it became glowing hot when pinched (and shorted) to the computer case :-) Work with the power off, and double-check it's on the correct set of pins. Don't let the wire get jammed in the computer door. While it doesn't really matter, if it makes you feel better, you can connect the red wire of the piezo, to the SPKR pin labeled +5V. 2) Start system. 3) If you hear zero beeps, based on your previous symptoms, it is CPU or DIMM. Since you've tested four DIMMs, and heard zero beeps, you replace the CPU. (Since the CPU was previously working, we'll assume the failure is not a coincidental failure elsewhere on the motherboard. *All* of my advice assumes computer faults are independent, and two silly things didn't happen at the same time. 4) If you hear three beeps, that tells you the core portion of the CPU still works. Now, we're still roughly in the same position. A pad (I/O driver) is blown on the memory interface, a pin is bent or damaged on the DIMM slot (unlikely, as you've tested all slots), or the DIMM is bad (unlikely, as all DIMMs tested give the same symptoms). So even if you do get beeps, it doesn't really change my advice, which is to test with another CPU. The core of the CPU can continue to work, even if the memory interface gets damaged, or has an I/O pad failure. On motherboards where the memory controller is inside the Northbridge, then the response is to change the motherboard, rather than change the CPU. But on the M3A, the AMD processor has the memory controller inside the CPU, and there is a 144 pin interface on the processor, that connects to the two DIMM channels and four DIMM slots. Either DIMMs are bad, DIMM power is down, or CPU memory interface is blown. So my advice above, is specifically for the OP and his M3A, and would not apply to every possible motherboard/CPU combination. I have a table in my head, of what to do :-) Based on the symptoms that the system previously was working, my assumption is the +5VSB helped blow out the memory controller interface = New CPU. Now, if you got one beep, it POSTed and booted, that would be a miracle. Here's hoping. Paul |

(When would you ever have seen a dollar coin? I'm assuming you're American and I've never seen dollar coins on your side of the border ;-) Now, if the piezo happens to have a 1x2 connector, that won't fit the 1x4 span of the M3A motherboard. If it was the converse (1x4 speaker wire, 1x2 type motherboard), you can move one of the pins out of the plastic shell, and move it to a different position in the shell. On the 1x4, there are tiny plastic tabs in each pin bay, that if *gently* bent outwards with a hobby knife, allow the pin and wire to be withdrawn from the shell. That's how you adapt a 1x4 piezo, for a 1x2 motherboard (such as a Dell/HP etc). Asus motherboards tend to have larger PANEL header areas, than Dell or HP systems. An Asus can be as large as 2x10, while a Dell or HP could use a 2x4 configuration, with 1x2 spacing times four wire pairs. A company making piezo speakers, isn't going to waste their time making all possible combinations of plastic shells on the end. So you can try taking a 1x4, and move one of the pins so that the span is 1x2. That's how you'd fit the 1x4 piezo, to a Dell or HP. Since your Asus uses a 1x4, that isn't necessary. Either the piezo you've been given has the right span, or it doesn't. If the piezo had a 1x2, you'd need to buy a 1x4 shell from here, and transplant onto the end of the piezo. Kinds pointless. I'd just go to the computer recycler, and get a regular magnetic speaker with 1x4 on the end, for nothing. (Example of a 1x4 shell, for home projects - make sure the pins fit, or buy a set of pins to go with it, if the existing pins don't fit. I'd just buy one of each, because the postage will be more than the goods. This is if your piezo, had a 1x2 on the end.) http://www.frontx.com/cpx075_3.htmlh...om/cpx076.html The piezo he gave me had a 1x4 connector and GR (Ghostrider) said the orientation didn't matter so I connected it and it worked. ******* 1) Connect piezo. Connect with power off. Greatest danger is * * bending a pin with the power on. The +5V, as far as I know, * * is not fuse protected. I remember someone relating a story, * * where they shorted the speaker +5V wire, and it became glowing * * hot when pinched (and shorted) to the computer case :-) * * Work with the power off, and double-check it's on the correct * * set of pins. Don't let the wire get jammed in the computer door. * * While it doesn't really matter, if it makes you feel better, you * * can connect the red wire of the piezo, to the SPKR pin labeled +5V. 2) Start system. 3) If you hear zero beeps, based on your previous symptoms, it is * * CPU or DIMM. Since you've tested four DIMMs, and heard zero beeps, * * you replace the CPU. (Since the CPU was previously working, we'll * * assume the failure is not a coincidental failure elsewhere on the * * motherboard. *All* of my advice assumes computer faults are * * independent, and two silly things didn't happen at the same time. 4) If you hear three beeps, that tells you the core portion of the * * CPU still works. Now, we're still roughly in the same position. * * A pad (I/O driver) is blown on the memory interface, a pin is * * bent or damaged on the DIMM slot (unlikely, as you've tested all * * slots), or the DIMM is bad (unlikely, as all DIMMs tested give * * the same symptoms). So even if you do get beeps, it doesn't * * really change my advice, which is to test with another CPU. * * The core of the CPU can continue to work, even if the memory * * interface gets damaged, or has an I/O pad failure. On motherboards where the memory controller is inside the Northbridge, then the response is to change the motherboard, rather than change the CPU. But on the M3A, the AMD processor has the memory controller inside the CPU, and there is a 144 pin interface on the processor, that connects to the two DIMM channels and four DIMM slots. Either DIMMs are bad, DIMM power is down, or CPU memory interface is blown. So my advice above, is specifically for the OP and his M3A, and would not apply to every possible motherboard/CPU combination. I have a table in my head, of what to do :-) Based on the symptoms that the system previously was working, my assumption is the +5VSB helped blow out the memory controller interface = New CPU.

But I'm probably getting ahead of myself. Let's figure out how bad this is first before declaring the desktop dead and moving on.... I gave you my diagnosis, and I'll repeat it again. 1) B channel on CPU memory controller has failed. To regain usage of all four slots for memory DIMMs, you'll need to test with a replacement processor. If a test processor determines a working A1/A2 channel and B1/B2 channel, then we know the original CPU had a dead B channel. If for some reason the replacement processor did not repair the problem, then it's motherboard. But the motherboard contributes next to nothing, to memory operation on the M3A. Only if a pin was bent, or the VDIMM regulator blew up, would the replacement processor fail to fix it. You've already told me a visual check of the DIMM slots reveals nothing. And your A1/A2 work, which proves VDIMM is working. Ipsofacto - replace CPU ! If you want to run with only two DIMM slots, use only A1/A2, then hold off on buying the replacement CPU for now. We have to work on our video. CPU is not a priority at the moment. But it has to be fixed eventually, some day. We want working video, to prove we're making progress. 2) The BIOS beep pattern is beeping about a video problem. You have discovered a video card fan which no longer rotates. This is a bad sign. Uh oh! In some cases, on fan failure, the heat from the GPU, melts the plastic body of the fan (which is confirmation of evil spirits :-) ) We term this a "double fault". And only testing, either temporary testing (using computer shop test CPU and test video card), or you purchase "worthy" replacement parts and test with them. If you do it that way, you risk spending more for the overall repair, than going through the computer shop. I repair my own systems... because I'm an idiot, and I wouldn't do it any other way. My worst case experience, I bought one new item, of everything. That's an expensive way to do repair, but it's part of the gamble of repairing your own stuff by yourself. Most of the time, I narrow it down to just the defective item, but I don't get lucky every time. Even a computer shop will guess incorrectly, and sometimes it leads to the computer shop suffering burnt out test components. That's the risk they take, and why the repair fee is higher than it should be - it helps pay for the stuff they wreck. ******* The bearing on the video fan has probably failed. The fan draws power from the two pin header on the video card PCB. The video fan does not need to be plugged into the motherboard, because there is a perfectly good fan header right on the video card. It will be a two wire fan, with no RPM measurement capabilities. Too bad the video card company didn't spend a few cents on a fan failure indicator! There is no point "just replacing the fan", because the card is giving us evidence it is dead. We won't know it's really dead, until a test card has been substituted in its place. Now you need to borrow a video card for testing. With same slot type as 9500 GT. The idea would be, you test to see if you can enter the BIOS, or get the BIOS screen up and running. If you boot into Windows with the new card in place, you'll end up running at a low resolution (like 800x600), depending on the driver situation. Some driver work may be needed, to get full resolution back. Uninstall original driver from Add/Remove, install new driver from video card boxed CD. We don't know the video card is dead. If the card is naturally a low power card, perhaps a fan failure won't kill it. On high power cards, there have been cases where a fan failure, leads to the fan being melted, as the chip underneath overheats :-) If we look at your motherboard chipset info... http://en.wikipedia.org/wiki/AMD_700_chipset_series#770 "770 One physical PCIe 2.0 x16 slot" So you should be able to use any PCI Express video card you can find in that slot. Subject to your power supply being able to provide enough power. If you buy a $500 card, the supply may not be adequate. If you buy (or borrow) a cheap $50 card, the power is likely to be less than 50W. For example, a Geforce 210 card is available for $30. Not a gamer card by any stretch of the imagination. And your local shop will likely charge a bit more than $30 for their Geforce 210. This is good enough to be a "frame buffer", but may not be strong enough to run "The SiMMs" latest version. http://www.newegg.com/Product/Produc...82E16814134157 Good luck, Paul |
