Try going into the troubleshooting tab of the advanced settings of your video card (Windows 2000) or
System Control Panel / Performance / Graphics (Windows NT 4) and setting the Hardware Acceleration
slider one notch down. This may also make your system faster and more stable, but it is possible that you
will not be able to overclock so far.

This may occur in Windows 2000 when the mouse pointer shadow is enabled. Disable it by going into
Control Panel / Mouse / Pointer and deactivating the mouse shadow.

Q. I get rolling lines with my GeForce2 Ultra. How can I fix it?
This problem appears only in GeForce2 Ultra cards, and looks like electromagnetic interferences with the
VGA-output signal. Depending on the resolution and refresh rate, the lines will have different size and look,
and may not appear in all resolutions and refresh rates.
Unfortunately there is currently no solid fix, although NVIDIA and several card manufacturers have reproduced
the problem and are looking for a solution.
Above all, if you have this problem,
please report it to your card manufacturer
, so that they know this is a
real problem that is affecting a lot of people.
In the meantime, you can try the following workarounds:

Try plugging your monitor power cable into a grounding plug (part # 61-2720 at RadioShack). This puts
the monitor on an isolated ground.

Try changing the refresh rate that your card is using. You might want to try just changing it by 1hz or so
by setting up a custom refresh rate. See the 'How can I manually set refresh rates and force the refresh
rate above 60hz?' question for more details.

You can also try altering the horizontal refresh rate of your card by a few hertz using PowerStrip. You
can download a demo of PowerStrip at the following website:


Try changing the resolution that your card is displaying at.

Try moving the monitor signal cable.

Make sure that there are no electrical devices near your PC and monitor that may be causing interference.

If the fan leads on your GeForce are twisted together, try untwisting them.

Try unplugging the fan on your GeForce card's heatsink. You will need to put in extra cooling measures
if you intend to keep your card in this state, such as putting thermal compound between the heatsink and
card and using a
Card Cooler or similar.
