I recently bought an extra 2 gb of this ram : Crucial Ballistix 240DIMM PC2-6400 DDR2 to go with my existing 2gb (of the same ram) and everything seemed to be going fine.

I then started to get Blue Screen's every so often and at the time I thought it might be to do with my new GTX 280 that i had also just bought. After a few days the errors disappeared though so I didn't follow it up. However, now they are happening quite frequently, and I either get a BSOD or (usually when playing a game) the monitor will suddenly act as if it has lost the input signal and just go to standby. When this happens, the sound seems to continue as normal except no input seems to be received from my keyboard (so when I press alt-tab to minimize the game for example, the sound still plays etc. - but obviously i've got no picture so i'm assuming it hasn't actually minimized back to windows).

I sent the new RAM back to crucial for a replacement, and it came. However, as my replacement was being processed I started to get the errors with my original 2gb as well. When i finally got my replacement RAM I took out the original sticks and just put in the new ones....BUT I'm still getting the errors!

Could this be just more faulty RAM...or possibly a motherboard issue? Or anything else? I've not heard great things about ballistix ram...

My Specs:
Core2Duo E6850 on an Abit IP35 Pro mobo
Nvidia GTX 280

Thanks for any help guys.

P.S. at the same time as the Ram upgrade, i upgraded my PSU to a Corsair 650W TX SERIES....not sure if it sounds like a PSU problem tho.
 
Yeah the RAM is at the correct voltage. I ran the MEMtest....got to around 30% with no errors then the monitor went blank again, so i'll try it again. It seems that maybe any intensive memory usage (such as games etc.) might lead to the error. But what are the chances of this happening with so many different modules of RAM??
 
I've discovered something that might indicate that it is indeed a PSU problem. When the error occurs, the LED at the back of the gfx card turns from Green to Red, indicating that there's supposedly an issue with power getting to the card.

Do people think this is the PSU's fault or the gfx card's?
