I've been trying to fix my wife's PC.

System Specs...
Athlon AMD dual core 2.2Ghz
Asus M2N-SLI Deluxe Mobo
2 GB Crucial RAM
ATI 1900XT GPU
Samsung 20" LCD
WD 250GB IDE HD
Seasonic 500W PSU
Cooler Master case
Dual DVD/RW drives
Windows XP Pro SP3

The system is about 4 years old and the problems all started with the video. The monitor came with 1 dead pixel, no big deal. All of the sudden on boot, it looked like you were flying through space from all the pixels that were flashing on boot. It got to the point where it would lock up and black screen soon after boot, but it would come back to desktop after a few seconds-minutes. I moved the PC into my workstation to work on it and the only difference really was the monitor. It went from being hooked up to the Samsung LCD, to being hooked up to an old ViewSonic CRT monitor I use to work on PC's. The monitor had been hooked into the white port on the video card from the Samsung, to using the blue port on the video card for the ViewSonic. I assumed it was the video card when I disabled the video card, and the system worked fine.

So...I ordered a new video card (GeForce 8400 GS) and popped it in and it all worked great. I continued to leave it hooked up to the ViewSonic while I did routine maintenance on it, until it was running very slick and fast. I then took it to hook it back up to her old monitor and thats when the problems started...it wouldn't boot again. I finally realized I needed to enable VGA mode and got it to boot, but every time I would try to resize the screen from 640x480, it would loose signal. Eventually the Samsung was showing a dark red color on the screen and now it wont even power up. I press the power button and the case lights come on and the processor fan spins, but it doesn't even make it to load the BIOS, so no beeps. From the time I push the power button to the time it powers itself down is about 2 seconds. I even trying resetting the CMOS by removing the battery and that worked once or twice, but hasn't since.

This is making me crazy (not to mention my wife wanting her computer back) so any help is appreciated. I've tried to tell you everything I can think of that might be of pertinence, but if any other info is needed, please let me know.

Thx in advance!

I would try a different power supply, if only to satisfy myself that it wasn't the PSU.

It sounds as if your Wifes monitor is eating video cards. The computer with the new video card was running fine connected to your CRT and the only thing you changed was connecting to your wifes monitor then poof all is lost. Along with testing the PSU I would send the new card back for a new one and try a Diff monitor (aside from yours).

Is that normal? I've never heard of a monitor eating video cards. Learn something new every day. I have RMA'd the video card back to newegg and await the replacement.
I tried another PSU w/ the same result.
I'm going on vacation later this week and will be back on Monday, so I'll post results next week when I get back. Thx for the help.

Since you tried the possibilities ( video card,psu,bad cable conn,monitor,bios settings)I would check for faulty ram.Try reseating or removing one at a time.
Faulty ram can do funky things.
