I recently performed a system restore on my Dimension 4600. I am using Windows Vista Home Premium. After the system restored and rebooted I see the dell logo then it goes to a black screen with mouse showing.

I tried rebooting in safe mood, same thing occurs. I used F12 to do a Diagnostic Test and everything was fine, still no boot. I tried a boot from lest known good config and still nothing. I put the upgrade disk in and tried to use that but the black screen just keeps coming up.

All wires are connected and everything was in working order. Please help, any information will help. I would like to try to save the hard drive if I can, but if I have to wipe it, let me know how I can do this. Thanks for your help.
