Black Screen White Cursor On Boot


Today I booted my old PC which has not been used in around 5 months or so. It is custom built with some fairly old components compared to today's standards. Upon booting I am greeted to a black screen with a white, blinking cursor in the top left of the screen. I am unable to do anything from here except reboot and try again. I have tried booting while attempting to enter the BIOS or Safe Mode but nothing happens and I end up at the blinking cursor again. I have attempted to reformat the disk with both a Windows 7 and XP disc, but again I am greeted with the blinking cursor. I am at a loss on how to get around this short of replacing the hard drive. I do not have another hard drive to test with, and without being able to boot from disc or enter the BIOS I am totally stumped with this one, any ideas on what I could do?

  1. Hi, Try clearing the CMOS (unplug the power cord and remove the CMOS battery for few minutes). At restart, it would wait for F1.
  2. Well if you can't enter the bios it's not the hdd that's causing the issue. All I can think is that something is wrong with your motherboard. It's obviously getting power since it's turning on. Have you tried to clear CMOS?
  3. I have reset the CMOS and it had gotten past the splash screen, registering devices. I did note that CMOS Checksum=Bad popped up. The computer notified me that a file or driver is unsigned and suggested I insert a disc to repair and reboot. Following it's advice I inserted my disc, rebooted and I am not stuck at the splash screen once again, the manufacturer splash screen, not the blinking cursor.
