Hello, I recently was away for about a month and I did not use my desktop for that period of time. I tried turning it on yesterday and it would show the BIOS screen and then a black screen. It doesn't display anything else. I tried searching this problem and have tried various suggestions. I tried removing individual sticks of memory to see if it would fix anything. The motherboard keeps displaying FF, but one time it displayed 7F. I'm not sure if there is a problem with my video card or hard drive. I unplugged my video card and completely removed it and brushed dust off and plugged it back in, but that didn't fix it. Sometimes it flashes some text right after the BIOS screen, but it still just goes to black afterwards. What I think is my HDD light blinks sometimes and sometimes it doesn't light up at all. Could my hard drive have died? Thanks for any help.
