Hello. I had Windows 7 Home pre-installed in my computer when I first purchased it 2 years ago. Recently, I installed Windows 8 Pro to try it, didn't like it, then installed Windows 7 Pro. Ever since then my computer has been constantly freezing, I can't download files (.exe/zip files mainly, haven't tried to download much else, they download up to 99% then never finish) but I can download images (jpegs, png). Images don't show up correctly online, often overlapping each other. Videos rarely play, they usually stop playing at about 2 seconds in, and sometimes whilst I'm playing games (Battlefield 4, usually) my computer just restarts itself, and when it powers on, it gives me an error saying windows has recovered from an expected shutdown and it tells me the problem was "bluescreen". I've installed every driver I can think of. I'm not sure what the issue can be. Oh, I've also done several malware/virus scans using Avira, Norton & Malwarebytes and came out clean.

Here are my specs, if that matters. Thank you for the help!

Carmel-2 Motherboard (HP)
Intel i5 2400
6 GB RAM
EVGA GTX 660 - 2 GB
Diablotek 750W PSU
Windows 7 Pro 64 bit
