Go into bios, and look in the hardware monitor section, tell us what the +12V, 5V, and +3.3V values are. The symptoms you describe could be the PSU not putting out enough power. Can you tell us the manufacturer of the PSU and it's max wattage and Amps rating? It should be on the sticker on the side of the PSU. The program you showed a screenshot of is good for some things, but is not good at reading voltages of the PSU.

We haven't heard from you lately. Are things any different? You said your PSU is a 230W. The GTS450 at idle pulls 130W and at full load can pull 220W. You PSU can't handle the load, it sounds like.

I changed the PSU. Thats why I havent posted anything. I added a 500W PSU. Still the same thing. The thing that annoys me a lot is that I must restart the PC after first boot up because it freezes on the log in screen. I type the password and it freezes, black screen.

The psu was from my friends computer. I just took it for testing. I am testing everything right now, should I also test the CPU ? The weird thing is that ubuntu boots fine

GPU: The test was running for about 10 minutes and there were no artifacts or anything. The maximum temperature was 91C.
HDD: All test (including SMART) were passed using SeaTools.
I will test the ram and cpu in for a several hours and post the results here
