Hi,
I have a 6 year old PC with Intel Core 2 Duo E6300 1.86GHz processor, Intel DP965LT motherboard and XFX nVidia GeForce 7600 GS 256MB graphics card. Of late I'm seeing different colour patches (dotted lines, - - - - - or : : : : at random places, all over the screen. These patches appear/move/disappear if I refresh the screen (F5) or move the windows around. The issue is more prominent if boot into Ubuntu (with GNOME theme) but not so with Windows 7. In Windows it happens only if I try to play some game at very high settings but is limited to the game; it doesn't affect my desktop as such after exiting the game.
I don't think it's the bad underfill problem (mentioned here, http://www.theinquirer.net/inquirer/news/1050052/nvidia-chips-underfill) since it happens even when the graphics card is heated up. I am not sure that it's the graphics card problem either, since the video memory tests don't report any error. It's not my monitor problem since screen capture using "Print Screen" has these patches.
So, are there any tools which can conclusively tell that the problem is with motherboard or graphics card? I'm planning to buy ATI Radeon 6570 1GB DDR3 if it's the graphics card problem but I want to be double sure before investing any money on my old desktop.
Also, is Radeon 6570 and overkill for the processor I have? I have 3 GB DDR2 RAM (512x2, 2GBx1) and planning to add 2GB more if that helps.
Thanks in advance.
