*Windows XP Home Edition
*NVIDIA gFORCE4 MX graphics
*1 stick of 512MB ram
I turn the computer and monitor both on. It usually takes anywhere from 1-4 cold boots of the computer before the monitor will power on (from orange to green light). The computer starts every time, booting up I see the big "e" graphic come up on the monitor, then it comes to the black "how to start windows" screen asking to choose safe mode, normal, etc... The monitor will power off all of a sudden at varied points in turning on the system. Eg: Directly after I get to the "how to start windows" screen, or directly after I select normal mode, or directly after I select previous good configuration, or directly after I select safe mode, or after the Windows screen before the login. The computer continues to run (all mechanical sounds still audible, all lights stay on the computer and the keyboard). It's just the monitor that powers off. One out of every 50 tries will carry me thru the login and all the way to the desktop.
Here's what I've tried so far:
*a different monitor, exact same problem
*unplugged all exterior and interior connections (cords & cables) and plugged them all back in, same problem
*took the ram stick out of one slot and moved it to the other, started computer, monitor powers off
*tried a different, brand new 512mb ram stick, same problem
*put both 512mb ram sticks in, started the computer, both are recognized under bios, monitor powers off.
*took the motherboard battery out, let it sit out for 30 minutes, put it back in, started the computer pressing the 'F' command to enter bios & changed the date back to current, save & exit, monitor powers off.
*Put a different battery in, started computer, same problem
*Tried starting the computer and pressing the 'F8' command to enter safe mode so I can try system restore. I select any of the options to no avail, monitor powers off
*tested a couple of old graphics cards in the additional slots (found out the T3092 while having a graphics card built in to the motherboard, offers slots to add video cards). One didn't do anything when I powered the computer up, but the other had the same problem of the monitor cutting off
*starting the computer with CA anti virus disc in it then with a windows xp disc in the cd rom, but the computer won't read either, just goes thru the motions as I stated earlier
The 3 times I've been able to get to my desktop since this has started happening, I was able to delete all cookies & temp files, empty recycle bin, add Avira antivirus program (after deleting all others), partially run virus scan and delete some viruses. One of the times, the monitor actually stayed on until the virus scan was 94% done, then powered off. The next time, after emptying unnecessary files I selected restart only to have the monitor power off and the computer stay dormant, not restarting.
I don't know what's wrong! I can't get the monitor to stay on long enough to work on it. Viruses?Malware? The built-in graphics card? Please help!
