Gigabyte GA-P35-DS3L mobo
Original RAM - Kingston 2x 1GB PC6400 800 MHz rated at 2.2V
New RAM I tried to replace - Kingston 2x 2GB PC6400 800 MHz rated at 1.8V
So last night I tried replacing my old RAM for 4gb of RAM because my CAD/CFD software has been maxing out my 2gb set-up. I bought the RAM and Fry's thinking they would work in my computer. By the way, I did not know they were 1.8V sticks until my computer crapped out on me, and pulled them out to have a closer look.
Anyway, my computer keeps turning on, and turning off, over and over again. It fails to give any beeps, so I'm assuming it failed or didn't go through POST. Could it be due to the difference in RAM operating voltage? I even tried resetting the CMOS and it still does the same thing. Turns on for a couple seconds (HD starts spinning, video card fan starts, etc.) and just turns off. After a couple seconds, it turns on again and does the same thing. This keeps on going unless I hold the power button, or cut the power to the PSU.
