My gpu used to work at 77C but now it overheats and goes over 100C

My cpu used to work at 60C, now it sees 75C ?

What could have caused the gpu and cpu to increase the temps this much?

The only change i made to pc is to add 3x4gb ram sticks.

I have a 600w ocz stealthstream (2.5 year old) i suspect its about die. Could a dying psu result in these temperatures?

It is probably caused by faultly fans or fans that are clogged with dust. Have you moved your PC at all? My friend built a cupboard for his so it was out of sight and wondered why it ran hotter.

the gpu is zotac gtx 560

Paste could have dried up (very unlikely), is the system dusty?

Are the fans spinning properly?

yes. I also cleaned the inside of the case with vacuum cleaner , no change in temps

Hmm weird, I had the same problem with my old rig (q6600 @ 80+ C @ idle lol) but it returned to normal temps after removing the immense amount of dust it had collected.

i'm about to go out and buy a new psu because its the only explanation i have for this situation. I had a similar problem like this 3 years ago , was fixed when i got a new psu

Has it become SUMMER in your place ?? :D 

The temperature difference between winter and summer can easily cause the ambient temps to increase, thereby affecting BOTH the CPU and GPU temps :)
