Photoshop weird pixel lines on the active layer

[Vlad Gheneli]

Hi,

I've bought a new computer one month ago. The configuration is quite good, i5 intel proc, 8GB ddr3 and stuff.
Everything went fine until one week ago, when suddenly everything started crashing and a lot of errors came up, firefox, games, diablo 3, world of warcraft, even blue screens.

My biggest problem of all is that Photoshop CS5 has a weird thing going on. Every time I start painting or even when I work on a photo, happened once when I tried resizing a picture, some strange pixel lines come up on the active layer and I have to paint over or erase to get rid of them.
I've attached a screenshot.
This is very frustrating because it wastes a lot of my work time and that has to be solved soon.

I even tried a windows reinstall, didn't solve anything. So I'm really thinking of giving it back to the warranty for checking, but they want extra money for the checking (of course) so I want to be really sure there's a hardware problem somewhere.
The video board driver started to have some issues when all those errors came up a week ago. I updated the last driver on nvidia website and the windows said there's an error regarding my driver. I then installed the driver again and it worked. Diablo 3 said that the driver is out of date (after I updated the latest drivers)

I honestly never seen something like this in 2 years of painting in Photoshop...

it looks like a graphic card issue, try to update your graphic card driver. if it won't solve the issue
try to do the same in Safe-mode and see if it happens there as well. if updating the drivers did not help
try to re-install the OS, and last resort will be replacing the graphic card. if you want to make sure the issue
is indeed with the graphic card. go into C:/ > Windows > Mini-dump - and look for error logs. using debugger you
can identify the issue. good luck.
