I had a same issue, When I was watching Drama on my pop player, my laptop g75vw ds73 has freeze with red lines. (there is not only red lines but also orange) Also, the line is not only across a laptop, but also the line covered whole monitor screen. So I should push to forcing the power button. and restart a computer. and it's fine... IDK what is the cause that it has happened . I could say that I recenlty installed Game Booster3.5beta from Iobit.

Well i have a G75VW-TS72, i had the same problem once, i was playing Diablo 3 then freezes up and everything went red colored, forced a hard reboot using the power button for 10 secounds then i didn't happen again, but since that time i had installed a fresh windows 7 and updated the video driver, i don't think it was a virus since i was using Kaspersky Pure 2.0 2012 at the time and after i install any thing after the driver i normally do i full scan... after the restore any problem so far? have you tried to update any drivers before this happen? i had a LOT of driver problems with my G75...

ForCeV can't agree more, i bought my G75 when i first saw the news of this model on Compusa back in may, the more that i dig up the more that i find more users with the same problems that i have, and the more that i dig up i see that is just drivers problem, like the sound driver for the subwoofer, the usb 3 after update, the red lines for the video driver... i'm very happy with my laptop since when it fully works i get the best experience from the very best.... but since it is new i just want it to work for a long time....

Edited: Also there are many things that can be done to correct these problem, i know that some times it takes time for a new driver or any update comes out, after all it only comes out if some one reports there is a problem with it... so in the forum there will be many users reporting some times the same thing in a different way, but some times the results in a future update... as some of my friends that has the same model that i have i would say that i would buy it again...

I know I'm a bit late to the thread here but anytime I have ever seen red lines on the screen like described it was the GPU. Just a few weeks ago I replaced a friends EVGA 8800 GTS which was producing static red lines at any resolution at all times on any monitor.

EVGA RMA'ed it as soon as I told them about the red lines persisting in any OS, resolution or alternate monitors.

I though it was the GPU but i did a stress test on the native resolution for 30 minutes and i got no error, no freeze, and the temperature was only close to 79 degress C, and i can play anything else on ultra high settings on any game so far, the only thing that i did yesterday is i have updated the video card driver with the Nvidia new Beta driver... maybe give it a try... and the thing is i can only see the red lines while playing Diablo 3, no other game would give me those not even Crysis 2...
