Please log in for more thread options My friend just replaced a memory stick in his computer , turned it on, there was a burning smell and the computer stopped. My query is this, can he purchase a seperate power unit (he says that that is where the smell is coming from, ir will he have to buy a complete tower and swap ll the good stuff over?

Please log in for more thread options If the old power supply uses a standard ATX plug he can easily replace the power supply. If the power plug is not standard he will have to buy a OEM power supply, rewire the new plug, or get a power supply and motherboard.

Hard to guess without looking at the system- but I suspect the module was installed backwards (almost installed, it won't fit due to keying but would go in far enough at one end to cause damage). So, the memory module and motherboard may be damaged. >

If that caused the power supply to fail, the power supply was either inadequate (or far more likely) a defective design, as even if the module were installed backwards and fried, even if the motherboard is also fried, a proper power supply should've shut down gracefully, only needing to be unplugged from AC for a couple minutes then it'd work again. Examine the memory module, it's contacts. If any are even slightly discolored, the board needs pulled and it's slot contacts carefully examined - strong light and magnifying glass may be necessary. If the contacts look burnt, go ahead and throw away the board. So you have 3 potentially damaged parts, one would have to determine which are actually damaged. Since the smell is reports as coming from the power supply, YES it can be replaced instead of the whole case, assuming it is a standard form-factor (and electrically, pin-compatible standard). However, consider a power supply- it's rear fan expells air from other parts of the system. If the case were closed and then turned on, any burning smell would be air sucked into the power supply (if not a rear case exhaust fan) and blown out the rear of the power supply. For this reason it could be possible that the power supply didn't burn, only appeared to as the smell came out of through normal exhaust flow movement. Google for pictures and measurements of power supplies. You dont' mention the system specifics so you'll have to figure out exactly what it is, the default/common being a standard ATX, or mATX on a very small-cased system. Older OEM boxes (like Dell or Gateway) were more likely to have non-standard power supplies. For the most part, "older" means pre-1999 or older. If friend is adept at using a multimeter, voltage readings can be taken of the old power supply. | ||||||||||||||||||||||||||||

Tha puts a whole new light on it. Didn't think it could have been expellde via fan in power supply. I know sometimes the Memory sticks are an arse to fit. Thanks for the help, I will pass it on.

Any idiot can match the notch(es) in the stick to the key(s) on the motherboard. Your 'friend' is obviously exceptionally stupid and shouldn't be allowed anywhere near a computer again - ever. | ||||||||||||||||||||||||||||
