PLEASE HELP pc signal problems
one day while watching some vids on youtube, my pc froze and a beeping noise came from the speakers. After rebooting pc it powerd up, and a black screen came on monitor saying signal unplugged etc etc. While smiling i replugged monitor cable into video card, turned it on and same problem happend. I replaced another video card into agp slot and it didn't work. Only tip i didn't do was to try different monitors, but i don't have another monitor. Pc is running and fans are twirling but the monitor is black saying signal unplugged. Please help as soon as you can!
