About a year ago I started having these glitches, they started appearing while watching video, but after a while they where nonstop and windows was unusable. I reinstalled windows 7 and everything was great. Recently a started to get them again and again they appeared nonstop and windows was unusable. I just installed windows 8 and its there all the time form the start. Combined with horrible metro, I can't do anything, I installed Ubuntu, and everything is great there, but in system info graphics is unknown.

What could this be ? it cant be burned video card, because games are +- still playable and Ubuntu works fine.

I've put the latest drivers, but its still like that.

My laptop is a HP G62-b40EY with and Ati radeon HD 5470.

Can someone please help me and say what is the problem? It is probably something with hardware, but do I need to replace video card or motherboard or can it be resolved without replacing anything ?

---------------- edit -----------------

I installed windows 7, everything is fine, until I install Catalyst control center or simply through windows update video adapter driver. Does anybody know what could be cousing this and how can it be fixed ?

You wrote everything worked again after you reinstalled windows 7. If you fully reinstalled win7 and its drivers and used the same programs (e.g. no gaming/GPU stressing before reinstall and low GPU using email reading afterwards) then this is probably a software problem. – Hennes Dec 31 '12 at 15:06
Even during windows 8 installation, there was this glitch, when there isn't anything there,but I've been going hard on GPU this last time when it occoured, and it occurs when GPU stressed – Kriss Dec 31 '12 at 15:49
