Issue with restart HD4850 Toxic

Also restart issues

Hi.

I'm having the same restart issues.

Whenever I restart the computer, the screen comes up with artifacts, making it impossible to read. It happens already at the post screen.

I have to shut down the machine to correct it.
There is no trouble when I put the computer in S3.

(I don't know for sure, but to me it sounds like the fan i running at 100% all the time: Has seen the other threads about the fan and it's okay)

My setup is:

Antec Performance P182
Corsair TX650
Gigabyte GA-EP45-DS3R
Intel Q9550
4 Gb OCZ PC-8500
Sapphire HD4850 Toxic
2 x 1TB Samsung HDD
Samsung DVD writer
Vista Home Premium 64 bit

I know it must be the Graphic card, because I switch it out with an Nvidia 8500GT and there where no issues with restart.
I also put the HD4850 Toxic in another computer and the restart issues appeared again.

Any suggestions on what it can be?

 

Random restarts

when you start the computer up press F8 repeatedly until you get a list of how to start windows, choose do not automatically restart on system failure. if your getting bsod's list what your getting here so we can further help you. IF the system is not getting bsod's and still restarting as you say then i would look into getting a line conditioner for your computer as you might be having power issues.
