ATI 4850 drivers crashing windows Vista

I have a computer running windows vista that continually crashes when putting the graphics card under any kind of load or after about 10 minutes of use.
I have tried every type of ATI 4850 drivers I can find and I am currently using 8.10.
I have tried both Vista 64bit and 32bit but still has the same issues. I have tried locking the GPU speed as this is apparently a possible issue. I have updated chipset drivers and flashed the BIOS as there was a VGA update fix. It always crashes when running the windows experience index at the testing CPU stage. This is a brand new machine. I have checked the temperatures of the components and all are operating at normal temperatures. Currently using a GA-EP45-DS3L motherboard and a Intel E8400 CPU with a Sata hard drive.

I have had an almost identical problem with the very same graphics card on a brand new Alienware PC. This is what i did to solve it- (this will seem like what you've already tried, but stick with me)

1.  use the System Restore to bring the PC back to its factory condition before you tried anything.

2.  go here to download updated drivers:     http://ati.amd.com/support/driver.html

3.  assuming you are using vista 64 bit, select the appropriate option, card series. etc. you know the drill

4.  now, the important part: you are given option 1, to download the full package, or option 2, download the display driver and catalyst control center as separate files. DO THIS ONE.

5. once complete, run/install the display driver first. reboot if it asks you to. once completed, then run/install the catalyst control center.

6. once finished, reboot the PC.

Like I said, i had an almost identical problem, and this fixed it when downloading the full package as one file did not. (restoring probably helped as well, as i tried most of the things you did)

hope this helps you!

After posting the question I wiped the computer again and reinstalled vista from fresh as I had made so many changes. From the fresh install of Vista 64bit I followed the steps you mentioned, but it didn't work. The computer froze after installing catalyst control center, but before the reboot. I reset the computer and ran the windows experience index, but it crashed again.
I have also checked the event viewer however there are no warning's or errors except from when I have forced a shutdown from when the computer has crashed.

I have managed to solve this issue myself after a few additional hours troubleshooting. Installed some old drivers (Version 4) that are compatible with the ATI graphics card. These installed without any errors and passed without crashing during windows experience index. A few additional tweaks required for my system to have it 100% but that's about it.
