Computer keeps restarting after installing AMD Display Driver

Hello,
after the fresh install I installed:

1. Network driver from the motherboard CD;
2. The catalyst suggested by the auto detect tool;
3. Network driver download from realtek;

Now that you asked I think it is worth mentioning, after installing the network driver from realtek site the system was stable for some minutes and I thought it would be OK. I installed flash and firefox. Just to check if everything was OK I restarted. Maybe in this minutes it installed some windows updates. Do you think it is worth a try a new fresh install without the network cable, network driver download and suggested catalyst?


Thank you

Hi again,
left it one hour with Prime95, no problem. I´m letting it on for the next 6 hours, I´ll post the result when I arrive home.

It is not crashing in safe mode. So we may easily consider that it is not the hardware related issue.

Can´t it be a GPU problem that only shows itself when the driver is installed and the computer start using its features?

I´ll install Driver Fusion and try removing the network driver. The generic driver was not installed after the fresh install, so the network will be marked as unknown device.

I think it will keep restarting because the first time I´ve installed just the catalyst without any other driver.

Thank you

Now I´m really puzzled.
The machine rebooted 3 times until I was able to download and run Furmark, after I started running it, the machine stopped rebooting. Run furmark with Prime 95 for 30 minutes without any reset. When I stopped both, after 2 minutes, it restarted.
