Can't get Windows 7 to boot with 4 gigs of ram

[Selig]

Greetings

After a bit of fun today I got Windows 7 loaded to my system, upgraded from XP. I was running 2gb of Adata ram and everything was running just fine. Then I decided to install the two Corsair XMS 2gb sticks that I just bought last week. I reboot and I get to the Starting Windows screen and it just hangs there frozen like a side of beef. I thought well, maybe it's the RAM so I put my original Abit sticks back in there and added a couple of 1gb sticks I'd just removed from the wifes pc after putting Corsair in hers. No luck again.

Is there anything I can do to check if windows just doesn't like my RAM? It shows up just fine in the BIOS but windows just isn't liking it.

Did a bit of research on my hardware

I have the following
Gigabyte GA-MA69GM-S2H motherboard
AMD ATHLON 64 X2 6000+
580W power supply


I also did a bit of swapping with my ram last night and found that I can use the 2gb Corsair sticks one at a time and it works fine. So it seems that when I exceed 2gb of ram then Windows freezes at the Starting Windows screen.

Any suggestions would be really appreciated.

MS is kinda funny. Any major hardware, even minor change, sometimes requires a fresh install.

Another workaround we use at my school that uses 4 different dell computers is boot into safe mode so it updates the os. to do this when your booting hit F8 several random times till you find the magic point were it gives you the option to boot to safe mode.
