CPU dead?

I'm having issues with my computer booting up. The motherboard logo comes up and then a white bar at the top of screen appears. Nothing else happens. I cannot access Safe Mode. I am able to go into the BIOS screen and tried to boot through CD/DVD with the OS cd, but that did not do anything.

When I opened the case, the CPU fan was not working and the CPU temp recorded 97C. I got a new fan and the CPU temp recorded 39C a day later, but no changes to the white bar. Since Intel says max temp is 72C... I am assuming that my chip is fried.

Agreed? Should I test anything else?

Specs:
i5 2500K (2nd gen)
Gigabyte AMD Radeon HD 6550
Corsair Vengeance 2x4gb
MSI P67A-C43
 
Try a different board first. I'm more willing to bet on a dead motherboard than a dead CPU.

seconded. With a bad CPU one doesn't see the motherboard logo.
there's a chance it could be a bad PSU as well. Voltage spikes at the wrong time can do interesting things to a system.
 
How do I test the mobo and PSU if I do not have a spare? I have a microcenter nearby and can certainly buy new parts to try out, but I'd like to avoid that if possible.
 
Does the CPU show up as the correct brand/model and verison in the bios? If so i think your CPU is fine. Usually the machine wont post at all without a CPU so it still could be the issue.

PSU are hard to test because you can test them to not be burnt out but if there not giving enough power to give to the cpu it will act like its ok but never power up.


From experience i would start with PSU then go from there. When your machines open does your mobo have a solid green led on??

Testing a PSU you just use a paper clip and into the 24 or 20 pin connector touch one end of paper clip to green and then move down like 3 slots to the black and push other side of paper clip to there. Then plug in the 3 prong cord like usual and it should power up the PSU (listen for the fan)

Thats the only testing you can do that does not test the voltage without using a voltage meter which you may need to do or get another PSU for testing.
 
Figured it out. Unplugged the recently installed USB 3.0 drive. DUH!!

Is it pulling too much power, or I have a dying PSU? I have a 750W PSU.
