I have a tower PC i bought about 1.5 years ago. I put a bunch of new software on it and it started acting funny. Then day I went to boot it and all I get is a blinking cursor in the top of the left hand of the screen. It goes through the POST but then just stops at the cursor blinking, no error message or nothing. I have changed the boot order in the BIOS to try to boot from a CD or DVD and I still get stuck at the blinking cursor. I thought that maybe it was a bad hard drive and swapped it with a known working one and also even bought a new one and neither of them worked. Running out of things to try and just thought I see if anyone here has any suggestions. I guess a piece of the hardware somewher crapped out and just wondering what it might be.
