Windows 7: Computer keeps restarting after installing AMD Display Driver

Can you tell me, what have you installed after the fresh install?
In detail and chronologically.

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

Do one more thing.

Run the computer in safe mode for a few hours, and see if it crashes there or not. After getting the result, we may infer about the reason behind the crashes.

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.

Hi again,
it is on for the last 6 hours without any crashes. Prime95 is running for the last 30 minutes.

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

In safe mode, download Driver Fusion and delete the network driver at first.

Then reboot in normal mode. At reboot, the generic network drivers will be installed. let us see if it crashes in this situation too, or not.

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

To be sure, you should take this test: Video Card - Stress Test with Furmark

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.

Got any error message there?
