Windows 7 - Sreens turn green

Every now and then (it's happened about 3 times in the 2 months I've had this computer) one monitor will turn a pale green with gray stripes and the other a pale lime green. I have to hold the power button to turn it off after that. Don't suggest to update the driver, I've already tried that and after that nothing worked right and I had to go though the process of uninstalling ATI's driver completely and putting it back on. Here are my graphics specs:
HP 2009 Series Wide LCD Monitor on ATI Radeon HD 5700 Series
SyncMaster 932BW/BW1932/932BWE plus(Digital) on ATI Radeon HD 5700 Series
ATI Radeon HD 5700 Series

Thanks for the help!

-(I will try and upload a picture next time it happens. )

That could be the result of a failing video card...

But my computer is brand new (Dell XPS 8100), how is that possible?

Everything is possible, it's electronics... sometime it fails even though it's brand new...

Green stripes mean the GPU is failing.

Well that sucks....
On a different note, when a hard drive grinds that means its failing too right? If so I really got screwed because mine is doing that as well....

To find out if your harddisk is failing or not, use S.M.A.R.T reader. Harddisks today have S.M.A.R.T in it, it's like a counter/log that counts it's up time, spin up, spin down, and logs - as in how many error in spin up, what's the current error rate, etc... Basing on those data, you can roughly understand how your harddisk is doing (as in is it healthy, or dying, etc). Some programs that can read S.M.A.R.T data: SpeedFan, HWmonitor, HWinfo32, etc...

edit: SpeedFan, not SmartFan...

Grinding or Ticking?

Ticking while the hdd is accessed is normal, how audible it is depends on the brand, model, and whether it supports AAM.

Well, it sounds like it is grinding... but here is the specs:
1000GB Western Digital WDC WD1001FALS-00J7B1 (SCSI)

FYI your hard drive is a Western Digital Caviar Black, 1TB (Terabyte). I recognize the model number because I have one. And if the hard drive is making "grinding" noises, that's not a good sign.

You might want to take your computer back to where you got it from and let them know of the problems its having.

No need in messing around with a new computer still under warranty.

My opinion.
