PSU problem Help Please

Post by **DMB2000uk** » Sun Feb 04, 2007 11:39 am

Hey all,

Puzzle for you. My friends PC is poorly, originally her 300w (I think) PSU died, not sure on the specifics, l can check sometime this week on if its burnt out like this next one though. Anyway one Of her student housemates replaced it with some nasty generic thing (not even Sure of its wattage ) and it worked for a while.

Sometime after or before this her onboard sound bit the dust and outputs garbled sound. Just recently her onboard video died too.

So I replaced it with an awesome 32MB Creative Blaster Riva TNT2, which got it working, but after sometime (the pc was left alone for a bit), there was a nasty burning smell and the pc was hung.

turns out that every 5v plug on the 24pin Mobo connector was Fried. Apart from a bad PSU what could Fry it like that? and do I risk blowing another psu if its a bad mobo? Any More ideas ?

I'd take the board out and see if the back of the 24-pin connector on the board is burnt or discolored. I've had some boards fried and some that worked, so who knows.

I had this happen to one of my ASUS A7N8X mobo's. It wasnt pretty

I had to replace the board, the main ATX connetcor on the board was melted beyond use!

BTW.... the 5v rail frying screwed up my video first, thats how I found the melted plug!

This is what my video looked like with no 5V rail.

DMB everything could be fried. The Psu electrically connects to everything, your best bet is to test each component individually in a known work system.

The screen looks nice

I would also recommend to test every single piece of hardware.

haha yes that pic rocks! I would consider replacing the mobo if possible. Every new piece of hardware you install in that box will continue to last about a week if you don't. Oh and look for blown caps also.

Yeah, i went with the replacing motherboard route, but the replacement one I got had a dent in it like someone had hit it with a large knife. The strange thing was that the actual box didn't look that damaged.

So even longer for me to fix this thing as I have to do an RMA now. Grrr..
