Yesterday i woke up to a computer that still had all of the fans on but no image and the mouse + keyboard were not receiving power.

I have since tried switching the monitors but both monitors responded the same.

Today I borrowed another socket A CPU from a friend and put it in, booted.

The computer booted to the bios and i decided to turn off the computer to reinstall the heatsink.

When I rebooted after I had installed the heatsink it did the same thing as it had done before.

The CPU i got from my friend was one that he had found in some old computer.

Is my motherboard eating CPU's? Are both the CPU's ive put in there busted and a new Socket A will fix it?

Any ideas are helpful! Thanks!

What does that mean? Why did it have to be reinstalled? If you did a half-assed install just to test it, you may have fried the CPU...if only takes a few seconds if the heatsink isn't installed correctly

At first I didnt even put the heat sink on. I booted it up, saw that it was working and turned it off. I put the heatsink back on and then it didnt do anything. Inbetween the two boots i felt the CPU and it didnt feel hot at all.


When I look at the CPU from the side with the pins in it there is a small brown spot in the middle where there are no pins. Does this mean the CPU is fried?

You can NOT run a socket A CPU without a heatsink, not even for one second! You fried it, dude. The brown spot says it all...

OK, if you have a socket A board that has thermal protection built-in, & provided you have it configured properly in the BIOS, it can be done. I stand corrected.

Obviously johnvining doesn't have this feature on his board, or he has it disabled. Regardless, his CPU is toast.

It doesnt matter if you have a socket a cpu, you should at least have the logic to put on a hsf!

With some CPUs, you could run a quick boot test without a HSF & there'd be very little risk involved...socket 7 for example. And it can probably be done with a P4 & A64 (both have built-in thermal protection circuitry), but it's definitely not adviseable. However, a socket A CPU is NOT one that will survive being tested this way.

I stand corrected also; I thought thermal protection was built into the Socket A CPU.

"With some CPUs, you could run a quick boot test without a HSF & there'd be very little risk involved...socket 7 for example."

Don't forget Slot 1! Certain S1 CPUs (The older ones with the thermal plates, not the newer SECC2 cartridges) will also survive about a minute without a HSF.

Yeah, that bit of info was totally unessecary, but Slot 1 is my b*tch; I had to promote it! LOL
