Hey everyone, I've been googling everywhere for a solution and searched through this forum without much luck, I'm hoping someone will know what's causing this. I was cleaning out the dust in my computer today and accidentally tipped the case, which sorta slammed to the floor onto its side. The PC was on the floor to begin with so I didn't think too much of it. So it just tipped over, I thought. Well... After cleaning I started up the computer and the BIOS screen shows up with the eMachines logo. Then comes a usual screen telling me "Realtek blabla boot agent, Press Shift-blabla to configure." From this point, the computer loads up a black screen with a flashing underscore on the top left corner and stops. All the fans are working and the CDROM responds to the open/close button. When I first boot-up the computer, the fans are working normally, but then as the startup continues, the noise dies down and the fans spin slower. They are still spinning by the time the black screen shows up, but they are slow enough so that you can barely make out the blades as they whirl. I tried going into the BIOS and found that my harddrive was being displayed on a list (so it's being detected right?). I've checked all the wire connections and everything seems to be okay. I've tried switching the harddrive for another older one, and the same thing happens. Though I must admit I'm not too sure if this older harddrive works... One last symptom: before the problem, whenever I needed to turn off the computer, I would have to keep pushing the power button for say... five seconds. Now, I push it, let go, and the computer turns off, just like that. I have an OEM version of Windows XP home, and I neglected to make any recovery disks, so I haven't tried anything with startup disks. My computer doesn't have a floppy drive either, so I'm kinda stranded. If anyone could help, I would greatly appreciate it.
