I have recently installed windows 7 home and 2 4g ram sticks into my computer, now whenever i run a game like Skyrim or Tribes Ascend the monitor will lose signal. my cpu runs at about 45 degrees Celsius. i think it might be my drivers for my motherboard but i have been unable to find drivers that will install without giving me an error.

my build:
16g G.skill ram
Asus P7P55D motherboard
Intel i7 quad-core 870
750w corsair power supply
GeForce 465

What error are you getting? Do you have the latest drivers? Make sure the connections are tight. PCI-e slot, video cables, connection to your LCD.
