I updated the bios and installed vista, went smoothly, then after the reset EVERYTIME I start the PC vista fails to boot and comes up with the options to start normally, safe mode, command promt etc etc, then it goes through the loading screen (green bar) then resets and repeats the process...what am I doing wrong?

I am now getting the following message

windows failed to load because the system registry file is missing or corrupt

It prompts me to repair windows by inserting the disc, but it wont start the repair, not even an option, just attempts to load windows

might be the 3gb+ of memory glitch. sometimes it installs but installs corrupted/doesnt start with more than 3gb, but still needs the patch to work properly.

take out 1 of the sticks of ram so theres only 2gb left, then set the boot order to start from cd, wipe the hard drive then re install (just incase files got corrupted during setup), then apply the patch for 3gb+ of ram from microsoft from here: http://support.microsoft.com/kb/929777/en-us and put the other stick back

Ok I'll give that a try. Just removed a stick of RAM and its ACTUALLY booted to the vista installation screen, I'll go ahead and reinstall Vista on 2gb and see how it works. Thanks for the help

Vista is installing, its copied the windows files and now seems to be stuck at 0% on Expanding files, its been like that for 30minutes...

As long as it starts moving at least 40min then don't worry.
It will normally tell you if its failed.
