Screen flickering problem

[Uncle Humjaba]

Hey all

Not sure what's causing this, but recently my computer screen has started flickering. It usually only happens after it's been on for a while, and restarting the monitor seems to fix it (sometimes). However, I've only ever seen it do this while in 2d mode (i.e. surfing the web, working on homework, etc.). I fired up L4D while this was happening a few minutes ago and the flickering stopped. It came back after I quit L4D.

Sooo is this a monitor issue or a driver issue?
I took a video of it happening:

I just made this video about 5 minutes ago, and it's been fine since I restarted the monitor for the video. I'm totally lost.

Notes:
* I have a geforce 260gtx, 192 core
* Temps on it are alright (gpu-z says 48*C)
* Temps on processor are fine
* Drivers are latest from nvidia, and this happened with old drivers as well (began happening spontaneously, not after some kind of change)
* Monitor is a soyo topaz-s, the always-on-sale one

My best guess is a failing backlight. Also check for loose cables and junk caught in contact pins.

Failing backlight wouldnt cause the half-screen freezes, and if you look in the video at :04 the steam window turns blue on one corner (seems almost like an overheating graphics card artifact?) Already checked cables and connections - everything's good

Nobody else?

So it nly happens in 2d mode ? Check your clocks on with RivaTuner, maybe it's like too much OC'd in 2d.

Tried to use different drivers? Tried to put the card into another system? Tried fresh install of windows?

Strange indeed.
