I got this e-mail from a friend today asking me for some help... the issue is a little beyond my knowledge... if anyone could help Id appreciate it.

currently I have 3 video cards I can use. one's a tnt2, one's a geforce2 and the other is something really really old that Im not even sure what it is (circa 1995ish...). I also have an onboard video, but its been set to be secondary. ... http://usa.asus.com/products/mb/socket478/p4s8x-x/overview.htm
I have been using the geforce2 as the primary for awhile now, and all's worked just fine. we wanted to watch a movie through the video out on my video card. the video out, however, seems to be connected to the onboard video card. we frigged around with some settings on the geforce2 and set it up so that my computer recognized the tv as the second display adapter. the audio was connected through a separate cord. anyhow, the video out thing on the tv never worked properly. there were grey squiggly lines the whole time, but not the normal kind of tv fuzz, it looked almost as if there was some electrical interference going on.
so we scrapped that idea and decided to just watch it on the PC monitor instead. we tried one more thing with the video out, and thats when things went screwy. I cant exactly recall what it is we changed, but it was a lot to do with the primary and secondary display adapters (tv vs. PC monitor)... so now, my current problem is this:
when I boot up my machine, it goes to the regular dos screen where its loading hard drives and resources and whatnot, where it says "hit del to run setup", etc. then it goes to the Win XP (home) loading screen with the green bar loading... after that, all is black. its not as if the monitor is off though, its just colored black on the screen. usually after a minute, a very large window (the resolution seems to be set at 640x480) comes up with an error message regarding lsass.exe failing to work. after you click OK, all is still black. I tried rebooting a few times, and running in safe mode. then when Windows loads, it says "safe mode" at the top and bottom like usual, but all the rest is black. sometimes we can see the cursor, sometimes not.
so we tried switching video cards, putting the tnt2 as the primary in the system bios... hoping that it would revert back to the settings for the tnt2, as I only switched to the geforce2 a few weeks ago. everything ran the same, the black was still there, in safe mode it still acted the same way. by then it was fairly late at night and I called it a day. I was going to make a Win XP boot disk here today, but I figure if its running in safe mode improperly already, I dont think a boot disk could change that...

any help is GREATLY APPRECIATED. thanks for your time...

Did you make sure to completely disable the on-board, then put whatever card you want in?
