This problem is gonna be the death of me..

[Codger]

I have a KT7a with Win98SE, Geforce 2 MX 400 etc.

This may or may not have anything to do with my problem but; I was having some problems with a USB device (a ADSL modem) - all my USB devices stopped working on the main USB ports. I reinstalled the modem drivers and finally fixed the problem by using the USB plate that plugs into the motherboard.

Anyway, ever since then, 7/10 times when I play DivX files (3.11 alpha or DivX4) the screen will go completely blank (but the signal is still being received because the monitor doesn't go into standby), i can't get out of it without rebooting the PC. Occasionally instead of the blank I will get a BSOD abotu viagart.vxd (the VIA AGP miniport driver).

I have tried:
-doing a 'soft' format (delete windows folder only then install windows again)
-reinstalling the DivX codecs
-reinstalling WMP.
-playing the files with a different software other than WMP.
-reinstalling the VIA drivers
-installing the updated via drivers in both Standard and turbo mode.

No luck yet (((

Anyone have any ideas?
