Ok Upon building of this new machine, I have came across so many BSOD it let me down, And made me think about buying a whole new setup or just buy a built one and replace the graphics card.

Now it wont even post the BSOD, Vista just tells me I recovered from a BSOD.

So heres the problem.

Problem #1. I cannot install all 4 Ram sticks, I have 2 In the Yellow slots, When I put 1 in the Black slot it freezes about 5-10Mins after OS Loads, If I put 2 In the black slots it wont post or Bios at all.

Problem #2. I got it to run with 4Gbs of ram, 2 In Yellow slots. But while playing games it will restart randomly or lock up. And on World Of Warcraft, It will give me a Error close and sometimes Error and Restart.

I installed all the latest drivers from ASUS and ATI. I didnt Update my Bios or Overclock just incase I need to RMA or Return.

Can anyone help?

if it helps, check that u have the latest service pack so it would support more ram.check the mem frequencies.u can check and make sure that there are not BIOS updates.you might have to set the voltage on bios.?
