BSOD while playing Dota 2

Yes, I have tried doing that around 5 times and still have files to repair. I just disabled verifier

Here's the sfc log, in case it helps:

Code:

2013-02-23 14:19:45, Info  CSI    00000799 [SR] Verify and Repair Transaction completed. All files and registry keys listed in this transaction  have been successfully repaired

There was many corrupted files, which have now been repaired.

Code:

sfc /verifyonly

The above command will only scan and check for corrupted files, it will not attempt to repair these files. It's best to check that all the system files are not corrupted.

Install and perform full scans with:

• Malwarebytes : Free anti-malware download
• Microsoft Security Essentials | Protect against viruses, spyware, and other malware

Remember to install the free version of Malwarebytes not the free trail; untick the free trial box during installation. MSE is the most lightweight and compatible with the Windows 7 operating system.

You can also view this thread for a complete free and lightweight security protection combination:

• Good and Free system security combination.

Both scans found no threats, and I also got a new bsod a couple mins ago (driver irql not less or equal):
ps: sfc still finds corrupted files

For the corrupted files, you can try a Repair Install:

• Repair Install

• Latest NVIDIA ForceWare Video Drivers Windows 7

1. Download Driver
2. Start Type: Device Manager
3. Expand Display Adapters
4. Right-Click Driver Name, Uninstall
5. Reboot
6. Run Driver Sweeper
7. Reboot
8. Install Downloaded Driver

Driver Sweeper will scan for any left over files from the old driver, old driver files can cause conflicts with new driver installations. Create a System Restore point beforehand, in case any problems or issues arise.

Driver Sweeper:

• Drivers - Clean Left over Files after Uninstalling

Code:

1: kd> !error c1
Error code: (Win32) 0xc1 (193) - %1 is not a valid Win32 application.

Downloading the lastest drivers now, will attempt both the repair install and the clean driver update. I'll post back as soon as I'm done

Thanks, post any updates :)

That's good to know, hopefully everything will be fine.
