Random loss of video/sound (crash?)

Within 5-10 minutes of booting up I will suddenly loose the signal to my monitor as well as any sound output. The PC is still powered as far as I can tell; the fans are spinning, the red activity LED on my case is lit up...

However, when I boot up in safe mode (as I am now), I don't seem to have any problem. I've scanned with AVG anti-virus and Adaware - negative for anything.
I've combed through my processes list, trying to isolate the problem, with no success.
This began just today, BTW, after I installed various updates via windows.update.

The thing that really gets me is that several times, I have not been able to get a POST beep, and had to wait several minutes before I could get a successful boot-up.

PC specs as follows:
Windows XP pro sp2
Intel P4 2.4, northwood
MSI 654M mobo
512x2 3200 DDR RAM
GeForce 6800nu
60gb IDE HDD, 120gb IDE HDD
 
Jesus,

Welcome to the Forums! :beer:

What power supply are you using and do you have a different one to try?
 
After a little more troubleshooting I found that Sygate firewall was the cause of the problem...
Strange, yes, but true.
The problem only occurs when the firewall is running. So I got ZoneAlarm last night and left my PC running untill now, whereupon I am using it. Problem solved, I guess.

And thanks for the welcome.
