I'm running a 660ti, so it's time to upgrade.

Oh, I see! I'm trying with an older HDD that was lying around. I'll mark the topic "answered" if that was the problem. Thanks a lot!

So I've tested both sticks and the problem persists but I only checked the RAM in the main slot of the motherboard. Could it be the slot? EDIT: Same results with different slots and sticks. EDIT: I just found out that both my sticks are running at 800MHz, they should be running at 1600MHz. Should I "overclock" them?

Thanks for the quick response! My drivers are outdated now because I used the motherboard CD to install them after I reinstalled the OS but they were up to date when the problem started. My temperatures are normal CPU: 13C ~ 26C. GPU: 34C ~ 35C idle. (HWiNFO64). I'll test the RAM to see if the problem persists!

Hi everyone! A while ago my PC started to freeze when I was watching a video on youtube in fullscreen (using Opera), then I switched to Firefox and after I while the same problem ocurred as well (my drivers were updated). I couldn't open the Task Manager and only a hard reset would work. Yesterday the problem started to appear in any application randomly, so I reinstalled the OS (Windows Home Premium 64-bit) and the problem persisted. Today I wiped the HD clean yet again and reinstalled the OS and it didn't solve the problem either. Both times I ran Malwarebytes, Avast and Spyware Terminator as soon as they were installed. Avast didn't catch anything, but MalwareBytes and Spyware Terminator caught something both times. I haven't plugged my external HD back since the first reinstall of the OS. Specs: AMD FX-8150 ASUS M5A97PRO 2x4GB G.Skill Sniper 1600MHz NVidia GTX 660ti 1TB of storage (I don't know the manufacturer, sorry) Zalman 600Watt PSU Everything in stock clock. Recently I changed the stock CPU cooler and a case fan for a Noctua NH-U12S and a NF-F12PWM and I (the PC froze here so I had to retype everything) also updated the motherboard BIOS. Thanks!
