I first got my bsod's only when playing bf3. Then I started getting them on firefox, and now it's anytime. I've ran dskchk /r /f. I only use Microsoft Security Essentials. I've restored to last known good configuration. I upgraded my ram because I thought it was the problem, but after buying 16gb of new ram, memtest+ gives me loads of red bars. I also can't update to Windows 7 64-bit SP1 (KB976932) from the Windows Update, it always fails. And I've tried doing a repair install for Windows 7 but I get an error code when I run my CD. Also everything has gotten slower on my computer, windows takes a little longer to boot, sometimes freezes for a minute and then starts working again, and a lot of things just stop working and I have to close out and restart them. Mozilla Firefox crashes a lot on me now too. I've attached all of my files, please help because I have no clue what to do and I've did literally everything I can think of to fix it.
