Well I currently have a Gateway 3.2 ghz pentium 4 with a Geforce 6800. Everything was great and my pc was working fine. So I just get back from a weekend vaction and for some reason my pc would began to boot, go to a blue screen for a very short split second, and than reboot. I tried running it in safe mode and still no luck. It gets into this loop of starting than restarting. Having lost my windows xp cd, I went and bought a copy of Vista. So I put in the disk and booted from the dvd. After a minute the dvd started to load, and than frooze. I waited for five minutes than restarted the computer. Now heres the odd part I need help with. Now when I boot my pc, no image displays on my monitor. There are no beeps, no display, and a little red light blinking on my motherboard by the small battery. I cant get any image on my monitor, I also tried a few other monitors with no luck. SO how do I get my pc to bootup! I need your help asap!!!!
