Lines on screen

[CheesePoofs]

Occasionally, I get these brownish lines that stem from the right side of my screen and stretch for the left, and somewhat follow my mouse around. Sometimes its just a few lines, but other times its a block that fills up most of my screen. They normally just last for a few seconds, but sometime they'll stay for a minute or two, or will turn on then off every few seconds.

I managed to capture one good picture of them. I had to take the picture quickly with a camera, because they dont' show up in a screenshot, so its not the best quality.

Any ideas about what this could possibly be?

bump.

what setup have you got?
any errors in event viewer?
how hot does your vid card run?
how long has this been happening?
did it start happening after you decided to oc, dl the latest Allinone Codec package, or install those cool drivers from some underground site?

setup is in my sig, which is:
AMD Athlon 64 3000+@ 2457MHz, DFI Lanparty UT nF4 Ultra-d, 4x512mb PC3200, ATI Radeon X800XL (made by ATI), Maxtor 160.0 GB @ 7200 RPMS, Samsung SyncMaster 793DF, and Win XP.

In the event viewer I've got a million disk errors, but there doesn't seem to be anything else. My video card is currently at 44C. Not completely sure how longs its been happening, but its at least 2-3 months. I'm using official drivers, although I know I did install some codec package a while back.

to me it looks like a monitor issue, maybe a monitor cable issue. try a different monitor or hook you monitor up to a different computer to rule this out , not showing up in a screen shot is a good clue

Yeah, if they don't show up in a screenshot, it's probably the monitor. I saw patterns sort of like that when I was putting a replacement LCD into a laptop, and it was getting pressure at odd places...which brings up the question - is this monitor an LCD?

Although....I just noticed that you say that it seems to follow your cursor around. THAT makes it sound like a videocard problem.

The monitor is a CRT, and a fairly new one (not even a year old). Its a SyncMaster 793DF.

Out of interest, what seems to be the most common 'disk errors'?

 

[CheesePoofs]

The disk error is: "The driver detected a controller error on \Device\Harddisk1\D." I'm getting about three a minute, all within 1-2 seconds of each other. I have a feeling that these errors are related to my backup HD which I pulled a week or so ago because it was clicking.
