When temperatures outside are high (80+ degrees fahrenheit), and I'm playing a game as well as having firefox and other things open (basically high loads), my computer will sometimes freeze up and power to all of my peripherals goes out, but the computer doesn't actually shut off until I hit the button.

I regularly monitor my CPU and GPU temperatures, and my CPU hovers between 35-45 degrees celsius while my GPU hovers between 45-55 degrees celsius. Someone mentioned to me that it could be memory failure, so I ran a memtest, but it didn't come up with any errors through 1 and a half passes.

I also just replaced my PSU which was my oldest piece of hardware so that can't possibly be the issue since it was happening before I replaced it.

Any ideas on what could be causing my freezes would be greatly appreciated.

My current hardware:
CPU: i5 2500k @ 3.3 GHz, ~3.6GHz
GPU: Nvidia Geforce GTX 560ti
Mobo: Gigabyte Z68X-UD3H-B3
RAM: 8 GB Ripjaws DDR3
HDD: 1 TB WD Caviar Black

If any other information is needed, let me know. Thanks.

Your CPU and GPU temps don't seem unusually high, but you say the freezing happens when the outside temperatures are 80+ F. I am assuming that this is a desktop system. When was the last time you gave the case a good cleaning? You could try to run the system with the side cover off as an experiment.

Someone mentioned to me that it could be memory failure, so I ran a memtest, but it didn't come up with any errors through 1 and a half passes.

To test your memory, I would recommend Memtest86+, run either from a bootable CD or Flash drive.
7 full passes for minimal confidence, 12-24 hours for moderate to maximum confidence, or until it registers an error. If an error occurs, test each memory module separately to determine the culprit.

I just recently completely cleaned every piece of hardware very thoroughly, so it's definately not dust built up. The only thing I haven't done is re-done the paste on my CPU, but I really doubt that the CPU is causing the issue. I will try running memtest for more passes to see if anything comes up.

People have said to me that it could be malware or spyware causing the issue, but since it only happens when it is hot that seems really unlikely to me. I'm kind of leaning toward it being HDD or memory.
