Hi, I've got a Sapphire ATI Radeon HD 4850, and recently I've been getting a lot of reboots and BSODs.
It always starts with both of my monitors getting covered in a chess-board type arrangement of grey or pink boxes, sometimes moving and sometimes still. Occasionally (usually if there are not many boxes, the amount varies), the screens will go black for a second and then come back again, and I will get a message saying that my graphics drivers have been restarted.
The majority of the time however I get a blue screen saying that the drivers have failed and then a reboot, or simply a black screen and a reboot. When I log back in, windows says that it has recovered from a fatal error, tries to find a solution and fails.
I've been monitoring the temperatures of my components using HWMonitor, and all seem fairly normal to me (CPU 30C idle, 45C under load; GPU 40C idle, 55-60C under load). Note that these crashes have happened both whilst gaming and whilst simply using the desktop, and once even on the login screen.
My drivers were completely up to date (catalyst 10.3, if i remember right), and I also tried rolling them back to no avail.
I've seen some people with problems with their graphics told to get a better power supply, and I'm wondering whether this is my problem, although I'll be honest, I know nothing about it really.
My specs are:
Windows 7 Professional x64
ASUS P5QL motherboard
Intel Core 2 Quad Q6600 CPU (2.66GHz)
4GB ram
Sapphire Radeon HD 4850 512mb
FSP Group ATX-450PNF 450W Power Supply
Any ideas? Thanks.
