Well I need to update the system specs I have written on the forums here I see - I'm running a 750W powersupply now, so that shouldn't be an issue.

Good eye, I didn't even see his specs in his sig, guess my resolution is too high.

450W is actually the min requirement psu for that card i believe....

EDIT: sorry that is 550W for that card. It should still start up fine i would think since the card is not under load.

And as for the fans my computer has a fan for the CPU itself, a fan for cycling air into the cabinet, a fan for the GPU, and one for the PSU.
Maybe the case is dusty? Or you have the ambient room temperature set too high, I know that some cases that rarely have any case cooling attributes usually overheat in warmer rooms.

Click on UserCP at the top of this forum and on the left of the new page should be a link called "Add System" or something like that, create a system spec and fill in all the information in the table, there which will put it into your signature like ours is. This will help other members determine what hardware you are running without having to repost it every thread.

Is there a lot of dust in your heatsink fins?

When you took the heatsink off the CPU you would have pretty much disrupted whatever thermal paste was on there. It should have looked like a blob of grey paste on the surface of the CPU and bottom of the heatsink.

I would definitely wipe both surfaces clean with cotton swabs and ISO alcohol, and when dry reapply a small rice sized grain of paste to the center of the CPU surface. Remount the heatsink tightly right on top of the paste grain and it will spread itself evenly.

Maybe you moved something while installing components.

Well funny thing is that I actually fixed a window yesterday in my room that was leaking quite a bit of cold air into my room. But after my computer overheated earlier today I made sure to open up the window to let in some cold air, and I turned off my radiator to make sure that my room wasn't too hot, so I guess that should have fixed it?

Did you remove the heatsink of your CPU before the issue has occured? If so you might have literally destroyed the thin layer of thermal paste applied, which would create airbubbles to form in the paste and air is a incredibly bad heat conductor, hence your CPU will overheat in a matter of seconds. Solution to this would be buying some thermal paste(I recommend Arctic Silver 5) and placing a little dot on the center of the CPU. Use a credit card or any sort of plastic card to spread it out.

Ahh that might very well be the case. Earlier when I installed the PSU I tinkered a bit with the CPU where I actually tried pulling off the fan to have a look at it, but at that time it was probably stuck to the CPU because of the paste.

I suppose what might have happened was that an increased room temperature combined with me trying to remove the heatsink+fan from the CPU while some paste was still applied might have caused the CPU not to get properly cooled thus causing too high temperatures leading to problems with the paste .. xD

Anyway I'll start looking for some paste tommorow to smear onto it and see how that works out.

Thanks a lot for the input from all of you

Well I didn't actually remove the heatsink nor fan, but there's a possibility that it might not have been sitting spot-onto the CPU and that might indeed have lead to the formations of those bubbles you spoke of.

I'll try going on a shopping spree as of tommorow to find a thermal paste to smear onto it.

Again thanks a lot for the input
