Windows 7: Win 7 64bit freezing up

windows 7 is freezing up completely, cant move the mouse or anything, its really annoying the heck out of me. its been happening for weeks. i have replaced my old video card with an evga gtx 465, i have tried my ram in all different slots, i have tried both sticks by themselves, i have ran memtest, prime95, i have ran data lifeguard to test my hard drive... i have updated drivers, i have put a box fan next to my comp to see if it was overheating. and there are no minidumps...

Did you run a antivirus scan and download and scan with malwarebytes?

Did you go to search and type event viewer and look for errors.

How about a clean boot.

nothing in event viewer other than the unexpected shutdowns every time it crashes, i havent tried a clean boot will though. and will try the malware. it has been doing this since i installed Windows 7 64 on a new computer.

I did not know that it started with the install. Did you do a clean install or upgrade?
An upgrade: you did not have to reinstall programs.

clean

Thats fine, then. An upgrade would have warranted a reinstall.

the only thing not brand new in my computer is my disc drive

If the clean boot and other suggestions do not work, try in safe mode. If you report results tonight, I will see it tomorrow.

gona goto sleep, i'll try some more after work tomorrow.

it seems to be getting worse, i can now log onto wow and it freezes withing about 10-15 minutes. i can play wow and watch a video and freezes within just a couple minutes.

but i can just surf the internet without it freezing, its just on games/videos, mainly netflix and gom player, i dont know if it does it on videos on youtube or anything alike.
