Windows 7 Memory Question (slightly OFF-TOPIC)
"GTS-NJ" wrote in message ... SNIP Ben, I have heard of this power supply/motherboard issue with eMachines. I currently own 3 eMachines; a T3306 & 2 T5243's. The worst problem I have had was the DVD burner self-destructed after a year on the T3306 which is almost 5 years old now. However, I have just purchased a docking station for my daughter's Dell laptop & took over her T5243 (you don't want to know the age of the Dell XPS it is replacing). It was dual-booting Vista & 7 but I downgraded to XP & 7. Now I am concerned about the power supply. Is it a standard PSU? Would a preemptive replacement with a new PSU prevent any issues? Also, on an off-topic note, I contacted eMachine by e-mail to ask what the fastest processor this motherboard would support (MCP61PM-AM). They wanted pay-per-call tech support to call me the answer. It currently has an AMD Athlon 4000+ (2.1Ghz). I have figured out that this is a Brisbane core running it at 65W. I think the 5600+ is the fastest at 65W but there are 95W processors running up to 6000+. Would you know what the fastest processor would be that would run natively on this board? Any help appreciated.....Thanks. Rich I have also seen many eMachines with fried motherboards after power supply failures. The Bestec 250W PSU is the one to especially watch out for (label will show Bestec ATX-250-12E). If yours is that model and you want to keep the machine for a few more years, a preemptive replacement is well worth considering. I have done this for a few customers. I'm leery or the Bestec brand because of this, but have seen reports that the later modes (like the 350W) have proper overload protection., See http://www.jonnyguru.com/modules.php...print&reid=154 for some interesting info. Particularly near the end "5VSB will kill your mainboard when (not if) the caps fail " Thanks for that link....extremely interesting & informative. Here are the PSU's in the eMachines': T3306 - Bestec 300W T5243 - Delta Electronics 300W I am inclined to believe that the problem is with the 250W Bestec model. So now I am cautiously on the fence about leaving the Bestec 300W in the T3306 & comfortable about leaving the 300w PSU's in the T5243's since it is made by a different manufacturer Delta Electronics. Would you agree?

I am a bit leery about any Bestec. They have an extremely bad reputation to live donw and jonnyguru has done them no favors. Nor should he! They deserve analyses like his. Maybe Acer-eGateMachines people read his analysis and showed the door to Bestec? ... Ben Myers |

Windows 7 Memory Question (slightly OFF-TOPIC)
In ,
Ben Myers typed on Fri, 24 Dec 2010 11:59:09 -0500: [...] eMachines along with HP/Compaq have used the trashy Bestec tower supplies known for taking out motherboards when they failed. I have scrapped dozens of eMachines boxes with perfectly good cases, bad power supplies and fried motherboards... That is very interesting Ben. I had two HP desktops with Bestec power supplies. And when they were four years old I stuck a new DLink wireless card in one of them. Then all hell broke out. Even when I removed the DLink card, the computer no longer worked by LAN or any wireless card. I did get an error message from DLink software and wrote it down. And I though something happened to the motherboard and what a strange coincidence. So I put that DLink card in the other HP. Dang, that one now has the same problems and no LAN or any wireless would work with this computer now either. Called DLink and asking them why their card ruined both computers and I gave them that error code. They told me it wasn't their card, but that error means a problem with the computer itself. So it wasn't their problem. Now thinking about this and you saying this about Bestec power supplies are making me wonder if that has anything to do with this problem? They work fine using dialup, but no LAN and WLAN ever works after that one DLink card was plugged in. Although today they are terrible computers and I am not interested in repairing them. But I am still curious what really happened. -- Bill Gateway M465e ('06 era) - Centrino Duo 1.83G - 2GB - Windows XP SP3 |

One of the other postings here refers to a detailed enginnering-level analysis and explanation of the serious shortcomings in the design of the Bestec power supplies, right down to a leaked capacitor inside. Interesting reading, and it corroborates what I have seen and other have too. If you ever decide to bring the HP (Pavilions, weren't they?) boxes back to life to serve a useful purpose, do yourself a favor and replace the power supply with even an old Dell one. Oh, never mind. They don't work with any kind of network. Fodder for electronic scrap... Ben |

Did a search on Google groups and was surprised to find almost nothing. I guess I should peek in here more often. ;-) -- Bill Gateway M465e ('06 era) - Centrino Duo 1.83G - 2GB - Windows XP SP3 |

It is the 250W unit that is known to have been the major problem. FWIW, I have been seeing quite a few recent HPs with Bestec 300W units and have not been recommending pre-emptive replacement. |

It has worked in my wife's T3306 for going on five years & is attached to a nominal home/office UPS with battery. Hopefully that is smoothing out any electrical spikes & anomalies.

Windows 7 Memory Question
Von Fourche;1265781 Wrote: A relative of mine needs a new tower PC and some other relatives are chipping in to buy her a low priced one. We found an E Machine. It comes with Windows 7. I'm on XP and know nothing of anything beyond Windows 7. I know my Dell is rock solid. It comes with an AMD Sempron 145 2.8GHz processor and 2GB of RAM. Will my relative get decent performance from this kind of machine? All she does is surf the net, pay bills, and do email, and maybe watch video on netflix. Her son does gaming on his x-box along with netflix. This PC tower is going for around $295 at Wal Mart. Thanks Hi, this is Ryan from the Windows 7 Professional outreach team. I think you might find this comparative chart (http://bit.ly/CmpreEd) helpful in getting the differences between the various Windows operating systems. Most systems have integrated to Windows 7, so it is the latest OS out on the market. |

We found I am less than thrilled with eMachines, which often use a crappy power supply (same as HP Pavilions and Compaq Presarios). When the power supply goes, it takes the motherboard with it, because it does not have protective circuitry built in. The world is littered with dead eMachines systems. I have tossed out a number of perfectly good eMachines cases, after stripping the boards for the local electronic recycler. A shame, too. The cases are generally well made out of sturdy sheet metal without sharp edges to slice you up... Ben Myers She currently has an old Dell with XP on it. Whenever it screws up I do a complete factory restore and it seems to run ok for a few days but then screws up again. I wonder if it has too little ram. I will do a factory restore and a week later they can't use Explorer to search the net. They have to use Chrome. Then the router which is hooked up to the computer and xbox screws up - only one is able to be used at a time. Either the computer can be plugged in and online or the xbox can be plugged in and online. There are ports for both the computer and xbox, it's a Linksys. But for some reason only one can be used. The old Dell may also have an old and failing hard drive. This is one possible explanation for a system going south regularly. I had an early machine with one bad memory stick, and somehow that led to HD corruption periodically until I diagnosed the bad memory and removed it. This was in 1995, I don't know if that could happen today. Or gremlins entering from the outside world... Ben Myers -- Andrew Hall (Now reading Usenet in alt.sys.pc-clone.dell...) |
