Here is the setup:

Intel P4 2.8 - B (Socket 478 533FSB )
Asrock P4V88 Motherboard
2 x 512 MB Corsair Value DDR3200 dual-ch
120 GB Maxtor IDE HD
16x DVD-ROM
48x24x48x16 CD-RW/DVD
350 WATT Premier Perf. Pro PSU
FD

Upgraded the video card to eVga 6800 - did not overclock or mess with it in any way. The PC had strange startup issues where it would wait a LONg time in POST while detecting CD drives - played with jumpers and cables and got the PC to go through POST somewhat OK. Unplugging the DVD-ROM makes it go flawlessly.

when the Pc booted to XP Pro SP2 the New Video adapater screen came up and didnt find the drivers. So I grabbed the official latest ForceWare from Nvidia site and the nightmare began:

Immediately after reboot windows logon screen go some distortion along the vertical lines separating the account pix and the Welcome frame. When windows loaded the desktop most of the bottom toolbar icons (like sound card utility) were garbled as well, and so were many of the desktop icons. The corruption seemed to spread the longer the PC was on so that most of the windows text and images became unreadable.

I panicked and pulled the video card out and replaced it with 5700LE - the garbled textures/icons came back after second reboot. I stuck the 6800 into my other box(where the 5700Le came from) and it runs flawlessly.

So far I ran Memtest86x with 100% pass, CPU tests with 100% pass, clean re-install of windows, thermal on video card shows 44 C, CPU 40 C, Mobo 30 C. The motherboard is 4 hours old, no sign of leakage on the capacitors. Re-installed the VIA 4-in-1 latest to no avail. Even tried plugging in another PSU with 420 WAtts after the garbled **** began and it made no difference :(

I apologize for a lengthy post but if I am missing something or you might have any ideas- please I am most open to try anything.

Remove the cards in device manager and startup in safe mode, if you see more remove them as well and try these utilities

Detonator R.I.P.

NVCleaner

you also have to remove any software that came with the probably in add/remove restart to normal windows then install the drivers for the new card.

Man you are good ! Rolled back the drivers to 71.25 WHQL and the problem cleared up in 2D apps however in games the horizontal lines came back not as bad as before. Rolled back again to 66.xx and BINGO ! Everything runs like a champ - my only guess is that the Intel processor itself or the VIA chipset driving it are to blame for incompatibilities with this particular eVGA 6800 and its latest drivers :(


thank you very much for a great suggestion.
