People I really do need your help here, I'm writing this from my father's computer. Here's what happened: During normal usage with firefox, my pc, an Acer M5640 suddenly decides to hang. Last time I scanned (last week) there were no viruses on it. So it froze, and after waiting a couple of minutes, I tried to get to the task manager via ctrl+alt+del. (My mouse was stuck too) This didn't work either, so I decided to do a hard reset. So I switched the thing off, waited some time, then turned it on again. A little flickering white bar appears at the top of my screen, and nothing happened, not even after 30 minutes of waiting. Then I turned it off and took out the power cable. I waited 15 minutes, then put it back in and turned on my pc again. I get the Acer boot screen as I'd normally get, but it hangs there. Now everytime I try to reboot, it either hangs on the boot screen (and doesn't react to button presses), or it hangs at the flickeringbar, or it gets past the flickering bar but hangs on a black screen. One of my neighbours is tech savvy, but he's on vacation right now and he'll only return on friday This is getting me really depressed so please tell me what to do! I have checked all the cables, I tried booting a windows CD and I looked around other forums already but all of them either had a laptop and required you to press fn+(some key) to get it to work, or it was a different problem. So nothing of that list has worked, please tell me what I SHOULD do.
