Hi everybody, was wondering if anyone could offer and explanation to what is happening on my screen.
I'm using Windows Vista Service Pack 2 and 2 days ago, my screen suddenly started showing these columns of green pixels...they are like train tracks..as in they bunch together in groups of 8 with lines of pixels parallel to each other...

you see it most clearly as windows is starting up on a dark background, it seems there are 6 columns that take up the length of the screen they move and flicker as I move the mouse.

I have 2 monitors and the appear on both monitors, so I dont think there is anythig wrong with them, i disabled the better graphics card I had installed myself, and reverted back to the one that came with my pc, but they were still here after doing this, however not as noticeable so I dont think its my video card. I havn't installed anything in the last few days so not sure as to what could be causing it...my Norton scans are coming back clear!!
This screenchot is of the desktop http://tinypic.com/view.php?pic=549jzs&s=7

Any suggestions you have would be greatly appreciated!!

Interesting .. I saw a similar RR Track pattern yesterday on a HP laptop running Vista
Then the pattern would change to the attached .. and Vista would not boot.
Even after performing a fresh install on a tested HDD .. The display and non-booting problem still existed.
I had to run an external Monitor to see all the Screen .. and it had the same display problem

The owner and I were thinking Mobo problems .. Since my Acronis Boot CD would not even display correctly.
I was wondering about doing a RAM test .. But didn't.

Sorry, I can't help more .. And welcome to the TSG forum

I'd have to check back with the owner .. But I was thinking the problem started with a display problem and got worse.
The only reason he brought it to me was because he knew I had the hardware to read the HDD externally and extract his data.

I can only suggest .. Do you have your data backed up .. and maybe run a RAM test ??
I was also wondering about a PSU problem .. but this was a laptop.
