I opened my computer up to clean all the dust out of it this morning. During this process I also took the heatsink and fan off of the CPU and cleaned that. Now I switched on my computer and it booted into windows only to shortly afterwards switch off by itself. I then tried booting it again and it didn't even load windows without switching off. I opened it up to check for any loose things and then switched it on and looked in the bios. I looked at the temp monitor and it was on 90 and was climbing very quickly at a couple of degrees per second. When it got to just over 100 the computer switched off.

What could this be I am without a computer now!!!???
 
You need to put some heat transfer paste on your CPU and heatsink as it is not transferring the heat.

Clean both the CPU and heatsink, put a drop of the transfer paste on the CPU and put the heatsink back on top.

There's a lot of different heat transfer pastes out there - from cheap to horribly expensive.
 
You didn't reseat the cpu properly. Make sure all the pins on the fan click properly into place and you can't budge them.
 
Buy thermal paste for 50 bucks and make sure CPU heat sink fan seated correctly. What CPU is it?

*thoughts of a noob with socket 775 HSF* :D :D
 
Luckily most modern CPU's will either throttle themselves or just shut down when overheating. You should still have a working CPU.

Silly question: Did you put it back?

If you did, did you make sure the clips were securely attached to the motherboard?
 
Sweet I put thermal paste and now it's averaging about 48

cooler than it was before I cleaned it!
 
Short of getting a new heatsink for your CPU there isn't much you can do. Only thing I can think of - did you clean all the old thermal paste off before you put the new stuff on? If not, do it again, this time cleaning both the CPU and heatsink, reapply thermal paste, and hey presto, you should get a few degrees lower.

Yeah I made sure it was all gone.
 
How are you measuring the temp ? The BIOS is not that accurate as there is no real pressure on the CPU at that stage.
 
Perhaps you used too much thermal paste. Im pretty sure I did the same to my heatsink and could get a 5+ degrees less on full load, but its temps are fine for now and I'm just too lazy to fix something that aint (properly) broke.
 
I really don't feel like taking it all apart again... :D

I put about a screw head amount on each side.
 
hey pooks

you shouldve put a blob of paste on the middle of the cpu, so that it'll spread outward when you put the heatsink on.
 
You're only supposed to use a drop half the size of a pea. I ended up using a pea sized drop by mistake hence my thinking I can still drop my temps. Only put paste on the CPU, and let the pressure from tightening the screws/you pushing on it a bit spread it out.
 
Hehe, it seems iam not the only one that suffers from heat with the CPU. Last night i put my E8400 in a spare g31 MB to see how far i can OC FSb on the board. The bios tell me the CPU runs @127°C :confused: After loading Win7 ive run coretemp on the sys and it runs @ 48°C with the CPU @ 3.6 Ghz with 400Mhz FSB. Dunno whats wrong with the bios.

Coretemp is a good way to see actual temp of the cpu during use.
