BSOD in LoL, now very frequent. Multiple errors.

[Gmanfreak]

Hello!
I've run into quite a jam here. I got a blue screen error a couple days ago while playing League of Legends that I believe was titled IRQL_NOT_LESS_THAN_OR_EQUAL, though it could have been something else. Anyway, I rebooted, ran a full system scan using Avast! antivirus (with nothing found), ran a LOLclient fix, and also played some Dark Souls to see if it was an overheating problem. Dark Souls ran fine, so I don't believe it's overheating. I discovered my NVIDIA card driver was out of date, so I went ahead and updated that with no errors. I ran League again, and the problem persisted. At this point I'm afraid I either have some corrupted system files or a very sneaky virus. I've blue screened multiple times following the first incident with errors including "File possibly corrupt. The file header checksum does not match the computed checksum." and even "A disc read error ocurred" at startup.Sometimes I will blue screen before I even get to the login screen, and sometimes my monitor simply displays nothing, or just the mouse. I'd like to single out the problem before wiping my drive, and I don't have a system reboot disc. Any and all help is greatly appreciated. Attached are the kernel files of one of the recent BSOD's, though I'm not sure which as I've blue screened a couple times after collecting the files.

Thanks,
Gmanfreak

Uninstall Avast using Avast Uninstall Utility. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

Let us know the results.
