I'm fixing my friends computer...the first motherboard had died...

so he came by today with the new motherboard. i install it and boot it...works beautifully...
i install a driver, shut the computer down...about 2 mins later try to turn it back on but nothing happens...

any one have any clue what is wrong?
 
I'm not trying to be an ass here, but there have been SO MANY threads of non booting PCs. No one knows for sure, because none of use are sitting in front of us. Just run through the normal trouble shooting options for a non-booting PC. Check connections, swap parts, etc.
 
There is no POST at all? You didnt touch the computer other than that driver?

Well, it sounds to me like you may have fried something. Try swapping parts if possible. Start with the CPU. Do you get any beeps? if so, what brand of BIOS does it have? you can check what a specific beep pattern means online according to the BIOS manufacturer.
 
i didn't touch a thing...

no post beeps...no fans...no hdd...no cd drive

mobo led is still on...

Hrrmmm... sounds like the ultimate death of a pc. I have had the unforgetable experience of frying all kinds of components and this is exactly what it sounds like. Suggestions before coming to this conclusion:

  • Check power cables on PSU and motherboard
  • Check to see if it IS connected to the surge protector/wall socket
  • Make sure all connections inside the case are snug (loose connections can sometimes prevent a POST)
  • Swap ram and expansion cards (for some reason an expansion card has prevented my system to boot before, turned out it was hogging up too much power)
 
For what were you installing the driver for? Dont really know how much this should have an affect on this but best to know everything that has occured before the problem. O yea just to make sure the light on the MoBo is on correct?

-cAB=
 
yeah when i put the new mobo in it was just updating the everything connected to it...and it asked for the video driver cd...so i put it in

mobo light still on yes...
 
Possibly the mobo is shorting against the case, remove the mobo and see if it powers up outside the case.
 
the thing is too...i have an exact clone of this computer which i built for someone else and it works perfectly fine...

but i'll try that as well...
 
i don't believe it is anything but either the psu or the mobo (which i doubt because its new)

anything else there still would have been post beeps...
if it was the motherboard, which was the situation with the last mobo, the fans would still run and the hdd would run too...
 
Best troubleshooting tip I can give. Dont doubt anything to the point you don't test it.

New stuff breaks all the time, in fact when you have a dead part over 1/2 the time it's within its first 30 days of use. New stuff=untested.

I have seen a bad mouse caues a machine to turn itself off, and this was before ATX with shutdown features in the power supply... Anything is possible, of course that doesn't mean ignore the obvious, just don't discount the odd.
 
very good point...i'll take that to mind...thanks

unfortunately i can't get this psu from my friend until later today because i'm at work and so is he...

so its on my mind pretty much
heh
 
Well I pretty much cruise the forums during my work hours, 9-6M-F CST, so I won't be around to answer you Qs over the weekend, so good luck, and let us know what happens.
 
for sure....
i'll keep you posted...hopefully its nothing too critical which will result into buying more and more parts
 
ok i tried a new psu...didn't work...i smelt the old psu and the new psu and the old one smells fried...

can that fry the mobo as well?
because the mobo smells like its fried as well
 
Yes, your PSU can take out your motherboard. Im going to say its either you CPU or your motherboard, along with the PSU. See if the friend that has the clone of your computer will let you swap with his parts. Then youll find your problem.
 
OK!!!!

i've found the problem...

the old psu was no good and burnt the mobo...
so we went to the store to exchange the motherboard because we only bought it 2 days ago...

tried the new motherboard with a new psu...works like a charm...

thanks everyone for all your help and suggestions...:)

now i can sleep well tonight
 
another thing too...i just found out
the people i built the computer for did not use a surge protector...

they plugged it straight into the wall

so i can stop beating myself up now
 
Ditto. That's exactly what I had in mind. Once the case temps inside hot too high that the psu crapped out and sent a ton of energy to the mb just before it died out too. Result: dead mb, cpu, and psu. :eek:
