I wanted to see if anyone else had any ideas. I just installed 2Gigs of ram (pqi POWER Series 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 333 (PC 2700) Dual Channel Kit Desktop Memory to be exact). The following day i was backing up a movie and my computer restarted. I didn't think any thing of it. I started to back it up again, same issue. The only thing that has changed is my Ram. I got pissed and took one gig out. After that it hasn't restarted in the last few days, when i took the Ram out it was not hot but i don't know how long it was sitting there. So do you think that it's the Ram over heating or the power supply? I'm leaning more towards Ram but I wanted to get a second option before I spend the big bucks for a heat spreader. Let me know what you think.

RAM heat syncs are inexpesive. If your computer restarts it may be malware or a trojan. When the CPU overheats your computer will simply shut off and you will be prompted to reset the CMOS jumper in some cases. Another thing is to check voltage settings within the designated volt range that comes with your RAM and always make sure its compliant with your mobo. I've seen mine restart when OC'ing my video card and playing a game too. Install some kind of temp. monitoring utility that comes with your mobo to verify that dangerous temperatures are not already being reached within the case.

are u running dual channel right now? also, what mobo do u have? Asus P5W DH Dlx C2D E6600@3.81GHz air CrucialBallistix 2GB PC2-6400 RAM 4-4-4-12 Sapphire Radeon X1900GT Mushkin XP650 PSU 640GB 320BG X 2 7200rpm HDD 36.7GB WD Raptor 2X DVD Driv

You should always test your RAM with memtest86 before putting it into service.

the mobo i have is a intel 845gvsr. i tried the same stick in both slots and i tried both sticks. one kept restarting my computer. from what i can tell it's a bad stick. :( I am sending it back and trying a new one.
