Cleaner for drivers for ATI/Nvidia. Use this tool to remove all traces of
old drivers. Reinstall new ones directly from Nvidia or ATI site.
Step 2.
Check Hardware Functionality:
A. Try to remove and re-seat the card, ensuring no dust or particles/hair
get's into the slot when you insert it. I suggest compressed air on both
the card's slot connectors and the slot itself.
B. Check your BIOS SETTINGS, see if something is enabled or disabled that
doesn't need to be. (Check your motherboard manual or consult help from
the manufacturer of card.) If it's under warranty, the help should be free.
If not under warranty, then I suggest you call and attempt some sort of
technical support from the manufacturer.
C. Check for heat issues. Is the fan spinning? If it is are the ram modules
hot? Is the heat sink on the card itself hot?
D. A couple other things:
What causes vertical colored lines on a monitor screen?
Answer
Either the monitor is going bad or the video card is going bad. If you can
get your hands on a spare monitor, try swapping it out and see if the lines
are still there. If they are, then the problem is with the video card.
You'll want to replace the video card if that is the case.
Answer
Ram modules can also cause vertical lines on a monitor.It's hard to believe
but i have experienced it multiple times.The ram is detected by the
system,yet the display is corrupt.If you open up the pc and touch the ram
modules the lines go away.This is very rare yet a possible cause and easily
overlooked.
Answer
The video card could be over heating which causes what you are seeing,
lines can also be called "Artifacts". Try opening the side of your case and
see if you see these lines. Also, it could be a driver issue, try cleaning
out your drivers using Driver Cleaner, and reinstalling the appropriate
drivers.
If you have another computer, if the video card is a expansion video card
(Meaning you have it in a PCI/AGP/PCI-E slot) try it in another computer to
see if the problem persists, if so your card is probably bad and needs to
be replaced.
E. Are you getting proper power to your video card? Check to see if your
power supply is the culprit. Sometimes a cheap power supply or a dated one
even can cause these issues.
F. Heat issues are the #1 cause of artifacts and striping. Check your
temps! A digital thermometer for say an oven would work great. I wouldn't
suggest borrowing it unless you get parental permission first or buy your
own.
Step 3.
Check your monitor and video card settings.
A, First learn how monitors work. Trust me it helps.

B, Check refresh/vertical sync rates. Most monitors and cards can run at
75hz without a hitch these days. Higher is usually better! VSYNC is a huge
problem what what is called "Tearing". Programs like Rivatuner can enable
these fine tooth settings.
C. Check direct x settings. Goto Start/Run and type "DXDIAG" in the box.
Hit OK/Run and then goto your Display tab. Run both tests. Do you get white
lines?
. I hope they get it sorted out soon.
