Hello, I have an ASUS X53SV (Intel HD 3000 + GT 520M) running Windows 8.1 and I've recently bought PE4C-PM3E adapter to try using GeForce 8800GT (with plans to upgrade). At first everything seemed to be ok, GPU was detected correctly and driver installed successfully but after a while I noticed that every few minutes the driver crashes and instantly recovers to function. Apart from that every time I try to run a game (Skyrim, DayZ, Garry's Mod) my computer hangs and i have to hard reset it. I've also tried Unigine Heaven Benchmark 4.0 and it crashes after 1 to 10mins when using dx9, almost instantly with dx11. Troubleshooting tells me that it's power supply's fault but i'm using 650W PSU that was powering this very GPU in a desktop PC so I don't really think it's power related problem. So what do you guys think is causing this instability? Also, I haven't bought Setup 1.x, do you think it would help? Thanks in advance.
