BIOS and Windows wont load once in a while!!!

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...

[kutless]

well. somethig new.. my computer froze then crashed this time. ...

I would return all those RAM sticks and demand a replacement...

[kutless]

So you think its my ram 100%  what if its not? could be anyting else... cpu or graphics cards??

[patio]

You won't be able to tell if anything else is amiss until you have properly working RAM in there...

[kutless]

so get new memory to rule out that out

[kutless]

It 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
