Experiencing Black Screen Post Installing Nvidia GeForce 210 & 9600 GT Drivers

Hello, my computer has:
CPU: intel pentium E5200 2x2.50GHZ
ram: 2gb 333Mhz (no name I think)
graphics: nvidia geforce 210 1GB DDR3 64bit
disk: 320gb sata II
motherboard: gigabyte GA-945GZM-S2
power supply: FORTRON PSP500-60APN


I did it myself, I left the computer with the winamp on, I come and I have a BSOD with the message stop 0x00000116 below nvlddmkm.sys resets the computer but immediately after loading windows I have a black screen I think I put the GeForce 9600 GT in the computer cleans the computer with the program as I remember unistall drivers display installs drivers to 9600 gt I restart and the same as on geforce 210, but sometimes I get BSOD with the same error. I reinstalled windows, it re-installs graphics drivers and still the same as windows finish loading immediately black screen and nothing else. Both cards worked earlier, there were no problems with them, the computer also had quite low temperatures, the graphics did not exceed 56 degrees while playing. Is it good to bet that the damaged disc or the PCI express input?

I'm sorry for not having Polish characters but I am writing from the phone if I bring my computer back to life, I will try to correct it.

I started the computer with integrated graphics and it worked normally. The power supply is not based because I have no other. I forgot to mention that with the 9600 GT there were little problems after buying it when I installed it to the computer, i.e. before the bios started to load, it restarted several times later it was okey but its performance was worse than on the GeForce 210 and that Live For Speed did not have fps lags I turned up the processor to 2.64ghz and the problem disappeared after some time strange things began to happen, namely LFS started to lag again, so I look to the bios and there the factory clock is picked up again at 2.64ghz saves and when it is about to start loading the system suddenly resets and turns on everything As usual, with the bios resetting, I decided that I would not have a match and somehow 2 weeks ago or 3 I returned to GeForce 210 and the problem with resetting the bios was solved as I set up 2.64ghz so I had it until today because I reset the bios manually but it did not bring I also reinstalled the GeForce 210 drivers from scratch, on the old win 7 system and on what I installed a few hours ago win xp and the same thing happens. The GeForce 9600 GT, surprisingly, was also a bit less efficient than the 210 which is very strange, I think it mixed me up and now something has broken. I did not have artifacts or something like that before, the computer also systematically cleans the processor, even after emphasizing it was not 25 degrees. Even when the drivers are loaded and when the black screen appears instead of the screen, we invite the cards as if they work because the fan slows down.

Please read what he writes? I uninstalled the drivers clean because at the beginning I thought that she was the cause of this behavior. I also put the system from scratch to make sure that nothing is happening in it, drivers for other things are installed, only what I do not have, how to check is the power supply voltage. I also reset the bios to the factory settings, I spent the whole evening looking for a problem in the drivers just to save time for myself and a person who would have to read it, but right I did not check the voltage on the power supply because, unfortunately, the multimeter was broken. The sex nest looks good as well, there's no dent in it or anything like that. Everything works until I install the drivers for one of the game cards.

The power supply in another computer works fine, that is, nothing else than a damaged motherboard.
