Theres something messed up royally with my computer. For about 3 days now everytime I go to turn it on, it gets passed only the first screen.(the one that says 'press delete to enter setup') After that a blank screen appears with a blinking _ in the top left corner. I've now found out that it isn't my hard drive because I took it out and hooked it up in a friends' computer. I'm using it right now actually. I haven't got the slightest clue as to what it is. I use Diskeeper, Ad-aware, Spybot S&D, Zone Alarm, CA AV, and Panda ActivScan very regularly. This is the first serious problem that I've had with my 3-1/2 year old computer. I desperatly need help! Anything will be greatly appreciated.
