I had built a computer about a month ago now. I installed the Windows 7 trial thing. its ran fine until yesterday. It booted properly. after logging in it gave an error message saying it needed to resart for a reason i have forgotten. it took serveral reboots to run properly. but it ran fine after that. today i started it up once booted fine ran fine did everything normal. powered machine off, came back a few hours later press the power button. shows "starting windows" does the little animation of the windows logo blinks a few times quicly then the screen goes completely black with just the mouse showing. the mouse can move but no other features work including ctrl+alt+del. any suggestions?
