The computer wouldn't turn on, simply.

And the CPU wouldn't work in any other motherboards.

Does the computer boot and run properly?

Yes - not broken
No - investigate

does CPU look discoloured or the socket?

Yes - burnt and probably broken
No - investigate other causes.

Need more symptoms to help further.

say a person (not me) short circuited the mobo and now he has a blinking vga led (after reseting the bios ) the cpu led starts blinking

The simplest way is to put the CPU in a known good motherboard to see if it works.

Not sure if you're being sarcastic or not, but I will tell you thats what a tech shop would do.

My guess would be sarcasm.

Unfortunately, although the OP is likely not happy to read it, there aren't 100 ways to tell. Either put a known-good CPU in the unknown motherboard or put the unknown CPU in a known-good motherboard. In either case, pray whichever part is suspected defect does not blow up the (formerly) known-good test part.

no like i said i'm just asking a general question i wasn't being sarcastic either i'm just never seen a burnt cpu to tell if it's burnt or not i'm just saying cpu burn sometime whether it's from a overclocking failure or it's just something else
+ i have hundreds of mobos at my disposal i work in a high end computer shop (microcenter wink wink)

Well, when people talk about frying a CPU from overvolting it or overclocking it, often they mean it literally, the CPU and the motherboard often will show physical signs of heat damage. Because of the tens of millions of transistors packed into such a small area, they're actually quite effiecient little space heaters. It doesn't take long before really bad stuff to happen.

Visually, since the CPU die is hidden under the IHS, there would be nothing to see unless there was a spectacular/catastrophic failure. Under normal circumstances, failures will either cause the CPU to lock up which drastically reduces power draw or trip the VRM's current limit, which shuts down the system. In either of those more common cases, there would be little to no visible signs of damage since shutdown would occur before a light/smoke show could begin.

ok here's the situation it's a pickle my friends and i working at microcenter and we raised enough money to buy ourselfs a employee gaming computer (15000 raised) now we wanted a new guy to help us build too so we let him so when we were all done wiring and organizing cables and etc the new guy was in charge of wiring the fans as a novice we told him to connect to whatever looked god to him (he said he was experienced) and that how all hell broke loose it booted up fine before but now it's just no good and i'm wondering if i have to call up a replacement or not

Burns on the lands/pins are still possible.

lol all the power on a single 1680x1050 resolution screen - and it's being driven by 3 GTX 690's?

Damn. You need at least 4 more screens to fully push that system. Or at the very least, use a Hi-res panel.


Basically what I would do If I were you is go over each piece of equipment 1 by 1. Make sure the motherboard is properly mounted...all the power connectors are connected in the right spots (don't have the GPU and MB power connectors mixed up).

uhhh yeah we were planning to push the moniter to a later date because we want to find almost borderless moniters about 3 roughly 25 inchs at least
