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?

Try a fresh driver install. Also when you remove them, reboot into safe mode and then use a program called DriverCleaner to remove any traces of old drivers.

Second, I would check in the BIOS for the memory timings and voltages and make sure that they are set to at least the Spec listed on the RAM chips.

If all else fails you might have to reinstall Vista and the drivers. I was getting a BSOD with my 4870 when I tried to shut Windows down and I couldn't OC it in CCC OC utility either untile I reinstalled the drivers.

Ram, 2 slots will 1066 dual channel, 4 slots will 800 only and maybe have some dual channel.
Some boards has slot 1, 2 or 1, 3 as dual channel and having 4 sticks installed = unhappy / slow speeds.
Asus and quality is well not that great. Currently Gigabyte then MSI and then Asus for quality / working parts / bios.
Biostar and 955 = stay away, lost 1 month and 8 motherboards as a result of Biostar .
940 and Biostar = no major problems, good overclock and 790g = low power usage as compared to 955 and no inbuilt 790g.

Send the 955 back and get a 940 = it works in most motherboards even Biostar without issues and performs the same at same speeds as the 955, the 955 is not worth the extra money and problems.
The 955 there is about / actually 5 motherboards that works with the AMD 955 junk "dual power plane" and bios issues etc etc etc.

955 is a nightmare period. The 955 is known as "Vista" of cpu's .

Best is to set everything to default latest bios update and run any of the linux livecd/dvd's or umbc cd and run a stress test / mem test from the cd to see how it works.
Any old half decent Linux livecd has all the drivers in so should work without problems, the Ati HD cards uses xf86-video-radeonHD driver so xdriver=radeonHD and not (radeonhd = defaults to old radeon driver without the caps and no good)
If using a really old / primitive Linux livecd then you might have to xdriver=flgrx.

The 955 needs huge PSU, so ram cpu video and other stuff = needs minm 575w to run decent and limited overclock power remains. 680w or more suggested.

Mwave had 575 "100% " rated logisys sli ready for $25, works perfect in my box.

Your Rosewill RP550V2-D-SL 550W

Efficiency > 72%

This means of 550w the 72% is normal and can max to 550w for maybe 10mins / 15mins about.
So it is actually about 360W PSU you are using = not enough power.
