Let me take a wild guess and that you are using an "EMACHINE" computer, well there's your problem, they usually use really cheap hardware, so walmart can sell it to you for less than normal price. "I got a great deal" not really! This sounds like a problem with the onboard video, just purchase a new video card, check to see if you are running agp or pci-E then just put the card in the allotted spot. Take care and good luck.
OK,I turn it on...lights flash on the key I see the big E symbol hear the normal beep and then It just stops...and a lil blinker in the top right corner of screen..SEEMS ONLY the F12 key works..no F8,10.....I tried a new monitor..same thing !
please help !
