I have 2x G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory

They worked for a while before my computer started crashing i dont know why...
well. somethig new.. my computer froze then crashed this time. ... I would return all those RAM sticks and demand a replacement...So you think its my ram 100% what if its not? could be anyting else... cpu or graphics cards?? You won't be able to tell if anything else is amiss until you have properly working RAM in there...so get new memory to rule out that outIt is not memory... Tested it with some other memory i forgot about... My computer does the same thing... I have two EVGA Nvidia Geforce 8800GTS Graphics Cards when i get my computer turned on once in a while it shows all three or four screens that i have setup and everything works correctly... could it be one of my graphics cards not working right sometimes? should i suspect CPU at all? Finally!!! .. I dont know what started this in the FIRST place but whatever it was it was dumb... When ever i remove second EVGA Nvidia GeForce 8800GTS graphics card it works just fine... when ever i put it in NOTHING shows up??? i will put this is the hardware part of the forums also. thank you everyone for dealing with me lol Sorry for jumping around but i suspected to many things and was thinking way to much my motherboard is dead contacted ASUS and just trying to the processor for a different motherboard hopefully both graphics cards work just fine.. although i did a test on ASUS to SEE what kinda of power supply i NEED for my whole computer and they SAID a 1000watt and i only have a 600watt lol im gonna have to get a new power supply or something.... im think im done with this post. thx
