|I have a longstanding problem that is similar to the original|
poster's. It might even be identical. For me the problem is
intermittant and generally only occurs at power-on. After a
few seconds, or sometimes a minute or so, it goes away.
Usually, the video comes on when a "CLS" command is
done during boot, after the power-on self-test has finished.
Sometimes it doesn't come on until after the OS is running.
There were other symptoms too complex to go into here.
When I asked about it here, the first thing I was told was that
it might be a problem with the power supply. I thought it was
most likely a problem in the motherboard, which could have
been damaged when I tried (unsuccessfully) to install the
CPU cooler that came with my CPU. (I bought a different
cooler from a third party. Much better!) The reply here was
that it was unlikely that I damaged my motherboard. I dunno.
In my case, the computer is obviously running because the
power light is on, the fans are going, the single POST beep
is normal, the hard drive is accessed, and when the video
finally comes on, the boot is either progressing normally or
has completed normally. I expect that it is similar for the
I have finally ordered a new power supply to see if that will
fix or change the problem. I still think it is more likely to be
the motherboard. I also have a new video board coming.
I really doubt the problem is with the video board, but that
*is* the most obvious possibility.
