I use the Nvidia Riva TNT2 32MB AGP Video Card.
Avast32 Updated Anti-Virus.
SpyBot Updated.

Latly i've been experiencing these onscreen grey, shady horizontal
bars fading off of any graphic displayed on my monitor from both left and right.
It looks as though the color bleeds across the screen. I've never experienced
anything like this before, and i've tried researching this on google, but i could
not find any solution to the problem.

I've tried swapping monitors with one i knew worked fine, same problem.
I ran a virus scan, everything turned up clean. Same with spyware/scumware scan. Nothing.
I've tried removing the video card from its slot, dusted it off, put it back in snug tight
and i still get those faded streaks.
I don't have another video card to experiment with, so i'm relying on expert advice.

One example i could explain would be right at windows 98 display screen when booting up.
Imagine taking a clean paint brush and running it across the freshly painted
Windows 98 text. That's exactly what i'm experiencing.

What do i do?
Thx for your help!

First thing would be to look for problems with drivers from Safe Mode. If you find more than one, Remove ALL that you find and reinstall the proper driver on reboot.

Second thing I would do is run HijackThis and copy/paste the log here for the experts (not me) to look over and see if you have scumware that the programs missed.

Third thing I would do is consider the possibility that you need to start shopping for video cards....:rolleyes:

"First thing would be to look for problems with drivers from Safe Mode. If you find more than one, Remove ALL that you find and reinstall the proper driver on reboot."

i did that, went to control panal, devices, display, riva tnt2, drivers, showed me 3 located in my windows/system folder. i deleted all 3 and rebooted. i get a messages saying VMM....(i forget the file)
cannot be found. if its not in your PATH you may need to reinstall windows. ok, so i poped in my cd that came with my pc (it contains all drivers for all the hardware). problem is, the cd runs in win32 and i cant start windows.

what now?
is there a way to install the driver for my video card that can run in the DOS screen when i use the startup disk?

What do you mean by: "the cd runs in win32"?? If you mean the CD won't boot, try going into the BIOS and set to boot to the CD first or use a boot floppy with CD support. If you don't have one handy, you can download one at Bootdisk.com (http://www.bootdisk.com/)

Edit: I believe Windoze should be booting with generic VGA drivers if you removed the current driver and the fact that it isn't suggests something else may be wrong, so the HijackThis log would still be a good idea.

It appears that you may have inadvertently deleted the vmm32.vxd file, which is the main Windows virtual device driver file that's required for booting Windows, when you deleted the 3 driver files that were listed for your video card in Device Manager.

You may be able to restore that file if you have a Windows 98 emergency boot floppy, and a Windows 98 installation CD(see 'Note:' below if you do not have the Win 98 install CD, and have just a driver CD).
You can make an EBF on another Win 98 system in Control Panel/Add-Remove Programs/Startup Disk if you do not have one, or go to www.bootdisk.com

Insert the EBF, start the computer, select 'Start with CD-ROM support' from the startup menu that appears, press Enter, and you should end up at a screen that shows the DOS driver for your CD-ROM drive, the CD-ROM drive's letter, and an A:\> prompt.
{Note: If you do not see a startup menu after you start the computer, then remove the EBF, restart, and enter CMOS Setup by pressing the specified key(usually Del, F1, F10, etc.) on either the 1st or 2nd screen, select 'BIOS Settings' or similar from the CMOS menu and press Enter, select 'Boot Order' or 'First Boot Device' and press Enter, select the FDD as the 1st boot device, press Esc, select 'Save all changes', type Y at the warning, reinsert the EBF, and press Enter}.

At the A:\> prompt type D: (or whatever letter is designated for your CD-ROM drive on the same screen) and press Enter, inset the Win 98 install CD, at the D:\> prompt type cd \WIN98 and press Enter. The prompt should now read D:\WIN98>
At this prompt type dir *.cab /P (note the spaces between dir and *, and between .cab and /P) and press Enter.
When you're prompted to press any key, press Ctrl-C (Ctrl and C keys simultaneously).
Next, type extract /a /l c:\windows\system base4.cab vmm32.vxd and press Enter.
When the D:\WIN98> prompt returns, remove the EBF and the Win 98 CD, and reboot the computer.
The missing vmm32.vxd file should now be restored, and Windows should load.

Note:
(1)If you do not have the Win 98 install CD and have just the driver CD, then do the above step, and type dir /P, instead of dir *.cab /P at the initial D:\WIN98> prompt, and press Enter. If .cab folders are listed, then press Enter until the D:\WIN98> prompt returns, type dir *.cab /P, press Enter, press Ctrl-C if prompted to press any key, and press Enter. If .cab folders are not listed, then type dir /P, and press Enter.
If the name of the top file listed is not base4.cab, then substitute the name of that top file for base4.cab in the command 'extract /a /l c:\windows\system base4.cab vmm32.vxd', press Enter, and continue as above.
(2) If the vmm32.vxd file is not found on your driver CD in (1), then find someone with a Win 98 system and a CD burner, burn the vmm32.vxd file to a CD, at the initial D:\WIN98> prompt type dir and press Enter, type extract /l c:\windows\system vmm32.vxd, and press Enter.

I had a backup hard drive which i installed windows 98 on, the drivers for all hardware, and i was getting the same video card problems. Based on this i was 100% sure the problem was my video card itself, not the drivers.

As for the other hard drive, i formatted that after i managed to backup any essential data i needed on cd-r. Basically i hooked up both hard drives and swapped files over from the one missing the vmm file.

I basically tossed the defective card in the trash and got myself the GeForce 4 64MB Card. Works like a charm... and better too! ;)

thx for all the help guys. i really appreciate it :)
