Since powersupply burnt out motherboard, what to do with components?
Krow wrote:
Hi All Since my last post about hoovering vs. powersupply; where for some reason my computer power supply took a 'power surge' or some sort (while off) and caused a burning smell, and popping sound *later testing resulted in smoke*; I took the computer to the shop, and the guy there said that the entire thing was a write-off. He said that the motherboard had been fried/burnt. However, what I do want to know is, how did he tell? I have looked at the motherboard closely, and have not seen any signs of 'damage' (then again, I'm just looking by eye) Also, would it have affected the Memory, the PCI Modem, the CPU (AMD-K6II 450) and the CD-Rom drive, floppy drive? How would I test them? Would I be able to install them on to a new motherboard in the same case (with new power supply) if they were unaffected? Many thanks in advance for any help or advice If this is the same shop which quoted you £100-200 for a new power supply, I'd purchase a £50 Enermax or Sparkle and install it myself. It's quite unlikely all of your hardware has been damaged. Even if your motherboard is kaput, it shouldn't hurt a decent power supply. -- Winerr 012 - Cash Underflow - Credit Card Number Will Be Assimilated |

Just be sure to get all your "damaged" parts back... Asking for this
usually results in "Oooohh.. Looks like it's OK after all." "Krow" wrote in message om...

Many thanks to everyone for their posts!
I took alook at the model/make of the power supply and its a KME 230W ATX branded capacity. This was installed 4 years ago or so, (I live in the UK btw) and I really don't know how good it is. The guy did mention that it had burnt the capacitors or something like that, and I'm pretty sure its the power supply that has gone. Besides, I'm a bit worried about opening up the power supply as I don't have the right equipment and skills to do it. But I still don't understand why the burn-out happened when the only thing I did was turn off the wall-socket switch and then turning it back on again after I finished hoovering from another wall-socket. He said that the power supply burn-out had caused the motherboard to go as well (mentioned transistors/capacitors/technical stuff) This wasn't the same shop that quoted 100-200 GBP for a power supply. This shop said the p-s was around 20-30 pounds (I think the make was 'Q-Tec') He seemed pretty decent, and didn't push a sale of another system, so I'm assuming that he must have done an ok job testing everything... oh yes, with ref to 'CMOS via jumper' - where would I find a manual or book or site that would show me what to do? Many thanks again KP |

KME = Key Mouse Enterprises, www.kmepc.com.tw I have one of their 300W MaxPower/EverPower PSUs, and I'd say it's one of the most cheaply made on the market. The fan runs only at full speed, it had no EMI filter, contrary to company claims, and the transformers were jammed crookedly into the circuit board. OTOH it did manage to put out its rated 190W of combined power (but I had modded the PSU by adding an extra diode pack in parallel to the +5V output) and didn't seem to be harmed when shorted. But it also had capacitors made by JEE, which some say is not the best brand and may have been involved in the Taiwan capacitor defective electrolyte scandal (one of mine failed in another brand PSU). |
