My computer.....MB MCP73PVT_sm, Intel duel core 2.53 Ghz, 2GB Ram DDR2 800 Hz, power supply 750w, video card GTX 650. I noticed the BIOS is showing the RAM voltage at 1.9v, but the RAM is rated for 1.8v. If I use 2 sticks of RAM, the video card crashes my computer. I get the BSOD. If I use 1 stick of RAM, no problem with the video card, everything is fine. The board can handle 4 Gb of RAM, but right now I can only use 2 Gb (1 stick). Could the RAM voltage be causing the video card to crash the system? (1.9v instead of 1.8v).
