Hi all, This has been an ongoing issue for months, but it had calmed down. But now the past few days it has become very frequent again - I am now getting totally fed up with it as I don't know what it causing it. I have a 4770k Intel Kingston 8GB 2400mhz ram MSI MPower Z87 Board AMD 290X video card Separate SSD, and 2 WD Black Drives in RAID I have attached the files. I just uninstalled as much as I can possibly think of but it just bluescreened again. Several times today already. I think it is a video driver issue, but it has only just started doing it more frequently after upgrading to 13.12 WHQL. I was running a beta before this, but the 13.11 WHQL version didn't help the siutuation so I reverted back to beta 13.11 9.4 as it wasn't happening often. Now I am back on 13.12. I have just removed my video capture card from the PC and uninstalled all its drivers. I have updated all the drivers that MSI Live Update detects, then uninstalled the program. This included the Audio Drivers, an Intel update, Motherboard BIOS update. Nothing has worked. Nothing is overclocked at all. Can you please help me out here? As I mentioned in the title it definitely seems to happen more when watching Youtube videos. I have updated flash to the latest version. It has never Bluescreened while playing games! Thanks a bunch. Edit: Just did a Windows Memory Diagnostic test - no issues. About to update my Intel Wireless drivers from 18.104.22.168 to 22.214.171.124. I'll keep you updated. Edit 2: Latest files attached.
