It booted ok and I formatted and installed windows fine. When it rebooted and started to load windows it froze at the loading screen.
Since this happened last night I have tried the following thinsg to try to fix it...
Changed over memory and then swapped it with different memory also.
Swapped graphics card
Flashed BIOS to latest version
Tried a different Windows CD
Formatted and reinstalled windows now 4 times.
I read that some people has problems with Gigabyte boards but they were all resolved by updating the bios. This did nothing for me and now im completely out of ideas.
You could start by checking your PSU voltage (even try a different PSU if you can), double-check all connections, make sure that the motherboard isn't shorting to a case post, etc. If need be, try running it outside of the case to see if it helps. Unfortunately reinstalling Windows doesn't resolve that type of issue.
