Tiny Green Dots and Computer Freezing on Startup

Hi my computer suddenly developed this issue of freezing after 2-3mins on startup. There is also some tiny green dots on the screen which I suspect might be graphical issue. I have tried installing older nvidia drivers and using system restore but the problem is still there. I was using the computer just fine this morning. I can use the computer without problem in safe mode but normal boot into windows and the computer will hang.

Anyone know what is the problem? Probably not hardware since i can boot into safe mode? Or is it overheating issue? :cry:

Computer specs (Can't really remember)
C2D 6600 2.4ghz
Nvidia 9800gt
Asus P5k Pro motherboard
Some 450watt psu

  1. Hello

    Seems like you have some artefacts on your screen, which are usually caused by overheating, instability or a faulty graphics card.

    You can check the GPU temps with Hardware monitor or GPU-Z. If you haven't overclocked the graphics card and the temps are ok then your graphics card may be faulty.

    I would also try a different monitor/T.V and cable if possible.
