Hello,

MY PSU died on me and received a new one yesterday. I hooked it up and all the fans ran, but it would not post. I went through the normal elements (BIOS reset, battery, etc...) but to no avail. I read here that one can do a CPU test by taking off the heatsink and running the PC for 5 secs or so. I tried it but I did not detect a noticeable difference. When I tried a second time I thought it was a VERY little warmer, but hard to tell. My question is, how hot should it get within 5 secs? Will it be considerably noticeable (even with good thermal paste)? Thanks!

Make sure ALL your cards are pulled out of their slots. one of them could be bad, preventing the CPU from booting the BIOS, which, of course, starts off with the POST (power on self test) which starts the beeping.

Only then can you determine if it's the CPU or something else on the motherboard.

Well I pulled everything. Put the heatsink back on the CPU. Turned it on. Fans spin, but no beeps or anything. What does that mean. CPU or Mobo?

Well it could be the mobo or the CPU. If you have another mobo that accepts the same type of CPU, you could swap it out to see.

Chances are that when you get another mobo/CPU pair, you won't be able to find the same type so now you are forced to upgrade. If you can afford it, that's to your benefit.

Was this failure a result of the CPU fan stopping and allowing the CPU to overheat (and burn itself to a cinder)?
or a power surge or lightening strike?

Have you checked all voltages for proper level and ripple? (easiest is to swap the power supply if you have another similar PC around- you can sometimes pick up old pc's out of the trash or at yard sales/pawn shops for far less than a new power supply would cost you).

Chances are good that all your data on the hard drive is still good.

I believe I've given you all the things I'd try before going for a new motherboard/CPU. If you do get new stuff, don't scrimp on RAM!

Best wishes.

I believe it was my PSU dying on me that led to the damage to the rest. I have no replacement pieces right now. I bought a new mobo to try the CPU on. If that doesnt solve the problem, I'll buy a new CPU. If the new CPU works on the old mobo, I know that was the problem. I will then return the new mobo for a refund (+ restocking fee). Hey, its still cheaper (in the long run) than taking it to a computer store and paying and extra $100 for them to tell me what I already know and still have to buy a new piece of equipment! :-)
