I have a Dell Dimension E521, running Vista with a bt keyboard and mouse. My
monitor went into sleep mode while running a spybot scan and now I cannot get
it to wake up. There is no response when I move the mouse or hit keyboard
keys. The batteries in the keyboard and mouse are good, just replace mouses'
and I had just been on the computer for 2 hours before this happened,
everything was working fine. The only clue I can give is that when I started
this two hour session windows popped up and asked permission for startup
programs to have access. I said yes, and went on to work for two hours. I I
have had an XP machine for years. This Vista was only purchased in October.
The two machines are networked. When I turn on the Vista machine, it is
louder than usual, and two lights flash on the front, 3 and 4. Any
assistance would be appreciated.
 
You need to check your manual in the troubleshooting tools section.

On my Dell XPS 410 lights 3 and 4 signify:
Memory modules are detected, but a memory failure has occurred.

We had the same problem - computer would go to sleep and monitor would not
wake back up, or monitor would enter power save mode in the middle of an
application. We reloaded Vista and we have not had the problem since.
