Overheated CPU, Now Won't Boot (HELP)!!

I know this seems frantic, but I'm at a loss.


I was moving around big chunks of files last night, and my PC/build (not listed in my sig) just shut down. I tried to boot it up again, and a 'CPU Overheated' error came up, but the only option was to continue.

It got through the initial boot/bios screen, showed the mouse on the blank screen, and proceeded to flash between the regular mouse icon and the loading icon. 30 seconds later, it shut down again.


I blew out a lot of dust from the case, removed the heatsink/cpu fan and found that the thermal paste was very dry. I let it cool overnight, then cleaned it carefully with q-tips and alcohol, put on new thermal paste, and started it back up.



SAME PROBLEM. Blank screen, mouse icon (which is movable when I move the mouse)....nothing else.


Did my CPU fry, or is the fact that the mouse is showing and moveable an indicator that something else is wrong?

First of all, try resetting the bios.

Well here's what I just did:


Did a forced shut down, as it was stuck in some weird boot loop/loading phase.

I unplugged all of my external hd's, and left only the keyboard, mouse, and monitor.

I turned off the power supply, and unplugged the mobo for a few seconds, then plugged it back in.

I then tried a reboot in safe mode, which is where I got the above image error. After I closed that message, I had a blank screen, so I formally shut down through CTRL+ALT+DEL.

I tried booting up again in normal mode, and it actually booted! HOWEVER...Windows Explorer kept restarting itself with error messages, so I shut down yet again (formally).

I turned off the power supply after it had been shut down, unplugged and replugged, and booted up again in standard mode.




Now it's up and running.

Using CPUID, my temps:

Cores:

~62C at idle

I got them up to 100C though when loaded, which is not good...?

You haven't said what the system specs are.
CPU
Motherboard etc.

Did you reset BIOS to optimal settings?
What did CPUZ say the cpu voltage is?

I'm running a ASUS P6T LGA 1366 Intel X58 ATX mobo, i7 920 a stock settings CPU, Geforce GTX 260 VC, Corsair 750 PS, 8gb OCZ gold.

I didn't reset the bios, I'm kind of wary to (I feel VERY inexperienced with the bios).

The CPU voltage runs between 1.06v and 126v. I'm using CPUID Hardware Monitor for voltage and temp readings.



I honestly think I may have mounted my fan/heatsink wrong, resulting in a bad mount/poor seal. It's operating fine, but heavy processing (when the cpu reaches 40% or more usage) makes it shoot up into the 95*C range.

Should I just get a new fan/heatsink and redo the mount? I also may have broken a pin in the current one...

Looks like a wide swing in CPU voltage, but I'm not familiar with that CPU.
If you only have 3 pins holding the heatsink down it can cause heating issues especially when under load.
I had that issue recently when I didn't notice I hadn't clamped down the HSF correctly on one of my servers and it was throttling back the speed while the BIOS alarm was screaming away.

So if you think a pin is broken you have answered you own question.

if you have everithing in the bios set to auto, like the cpu vcore then its a very normal volttege, but the temps are way to high, try at least a new mounting of the cooler, because playing with it by those temps is not good.

in the bios load optimal defaults and save and exit. simpel.
ore just look if you see a clear cmos button to restet youre bios.
ig you dont see it, just take out the battery for a few minutes.
and you reset youre bios.
