I think my CPU is dead

[gollum999]

I think my CPU might be dead, but I want to get some more opinions before I send it in for replacement.

I just moved to a new apartment. I set up my computer a few days ago, and everything was working fine. But the other day it froze and wouldn't restart. It doesn't even get to POST. When I turn it on, the lights all come on and fans spin, but I don't get any video signal or beeps from the onboard speaker. I've tried just about everything I could think of:

• 
  ■ Re-seat memory, swap slots, only one stick in slot 1
  ■ Remove everything except memory, graphics card, CPU, and cooling
  ■ Remove graphics card and just listen for beep (since I have no integrated graphics)
  ■ Reset CMOS
  ■ Take motherboard out of case, run from desk
  ■ Swap motherboards (same model, refurbished and never tested by me)

Nothing seems to work. I think that narrows it down to the CPU or maybe the power supply. Considering that everything seems to turn on, I feel like the PSU is working... but I was planning on upgrading it anyway, so maybe I should run out and get a new power supply just to be safe and make sure that's not the problem?

I'm not sure. But I wanted to see what you guys think. Anything I am forgetting to test?

CPU's are solid state devices that rarely ever die. PSU's are prone to failure.

i would take everything apart and put it back together, which you have kind of done. if this does not work then it is porobably a CPU problem

The cpu is the least likely thing to die. How exactly does taking it all apart and putting it back together point to the cpu?

Sounds like a PSU issue to me.

I went out and bought a new PSU just to make sure. No change. 🙁

im just saying it may be a faulty connection
