I've had a couple of problems within the last few days, but even though they have similarities, they also had quite different aspects also, so I'm not certain whether they are related or not.
The first time I got a blue screen when I had Disk Management format a hard drive that had disappeared from view, and on restart the BIOS run was pretty much normal, but all I got after that was a black screen. After getting the same results after attempting to boot several times, I just waited a few hours, and it then booted like it should have.
The problem I had tonight occurred when I simply plugged my barcode reader into a USB port...everything just froze. After a forced reboot I got nothing but a black screen with some BIOS beeps. They sounded like two short ones, followed by eight long ones, but from the list that I found, I guess the two short ones didn't count, because they were not on the list. The closest I could find was as follows:
"8 Beeps
Eight beeps means that there has been an error with the display memory. This beep code is usually caused by a faulty video card. Replacing the video card usually clears this up."
This makes some sense, because I later found that the system did reach desktop, if I waited long enough (determined by audio output), but the screen remained black.
I then just shut it down for a hour or so, and decided to try once more. This time it went ahead and booted normally with full video and no BIOS beeps. That would suggest to me that the problem was heat related in some fashion, but looking at the temps in SpeedFan now doesn't indicate any temps above normal.
Would video memory be able to overheat, without being detected by SpeedFan?
