Hi for everyone. First of all, sorry for my BAD english Second, i have a big problem with my graphics card... when i'm trying to load gpu with some bench tests, graphics card always squeaking like a pig. And after couple seconds, screen goes black for 2 sec, and it turns on, and pops up message saying that "nvidia drivers stopped working and has recovered". I have "INTER-TECH IT-SL500" PSU... There is no PCI-E 6 pin power, so i installed 6 pin connector by myself from molex and sata pins. 2 black x 1 yellow, 2 yellow and 1 black. I also tried to replace RAM sticks. When GPU on benchmark, all pc fans slows down. I tried to power graphics card with other PSU. So my pc was running with 2 psu, but nothing... same problem.
