Monitor display problem - patches of flickering dash lines

\015 I have a HP lcd monitor HPvs17e. About six months back, due to blank screen (cannot boot), the repairman changed my nvidia GeForce grahics card to GeForce 7100GS and everything was OK. About two months back, I started getting patches of short repetitive dashed lines on my monitor display. On white background, the dash lines are pink. On other backgrounds it is different colour - example, green. It's worse while viewing videos online. \015\012\015\012I scan my hard drive with anti virus, anti-spyware, did a disk cleanup, defrag, registry clean, and even did a system restore to a date before the problem started but didn't help at all. I even took out the graphics card to brush clean; uninstall and re-install the graphics software.\015\012I changed the monitor, also using another video signal cable and I still get the same problems. The lines are getting worse (more). Attached is a screen shot of the display (green dash lines). Anybody can tell me what the problem is please.\015\012\015\012If graphics card need replacement, how do I choose the right graphics card to replace?\015\012Many thanks.\015

Answers :

It does sound as if the graphics processor of the video card has died but I suggest downloading the lastest driver for that card on the off chance it is simply a software hiccough.

\015\012If, after installing an updated driver it is still there, you might try changing the resolution via the Control Panel/Display, to see if the anomalies change in dimensions but this won't cure anything, only confirm that the card is at fault.

\015\012These cards are, on the whole, pretty reliable but your luck sure hasn't been very good.
Has anyone ever seen such? This is a screen shot of my wifes HP Laptop. Fresh driver, updated DX, hooked it to a monitor and sent this to a few friends much smarter than me on computers. Lot of trouble shooting by direction but no results yet. Anything would be greatly appreciated.
