I've got some weird problem after upgrading my video card I've been trying to resolve for weeks. Previous Config: M/B P6T Deluxe V2 PCIEX4_1: Anker USB3.0 card PCIEX16_1: Radeon 6950 2GB PCI1 & PCI2: nothing PCIEX16_2: Sound Blaster X-Fi Titanium HD PCIEX16_3: Intel Gigabit CT card Everything worked fine for years, until I replaced the video card with XFX 290 4GB. After that I've been getting numerous BSODs with A000001 bugcheck in the video card driver in games (Diablo3 and few others) or just watching movies with VLC. When BSOD happens usually it was with some sound bit looping. This morning my Win7 had an issue starting up - took more than 5 minutes to get to the login screen and after login it was all messed up with a bunch of failed services, including creative audio. Tried to reboot multiple times, but no luck. Eventually I had to pull out the sound card out and after that Win7 booted normally. What the heck is going on? Is X-Fi somehow okay with PCIE2.0 card in x16 slot and not okay with PCIE3.0 card?
