Installs fine, reboots and hangs

Okay so I bought the W7 Pro Upgrade 64bit using the Student download via Digitalriver.. I downloaded it on Windows 7 RC2 32bit and I followed the steps that was posted in the error thread to make an ISO file and I booted the disc and installed 64bit. Everything runs fine except when I get to the final phase of installing and it restarts my computer, the computer hangs at the Windows is starting up screen..

I did a custom clean install by the way.

AMD 5200+ 64 dual core
4gb ram DDR 2 ram
nVidia 8800gt 512 gfx card
Sound blaster audigy ls 5.1 sound card
can't remember what MOBO i have exactly but I believe it's Asus.

Someone said to try disablign the secondary LAN in BIOS but that was already disabled for me and it still doesn't work..

Please tell me I didn't waste $40

Any help would be extremely appreciated!

Well, you might want to try removing the sound card and everything else you can.

I think it is hanging in the area of checking performance, so it might be a driver or hardware problem.

No messages at all?

Ok I got it working. I had to take out 2gb of ram and unplug my secondary monitor.

I can get to the desktop perfectly fine BUT only on 2gb of ram...

Both sticks work, I tested them in the 1st slot, but any time I want to put 2gb back into any of the other 3 slots, Windows hangs in the Starting Up screen..

I don't get why my slots would stop working all of a sudden... they were working perfectly fine with XP and 7 RC2.

Do you have any manufacturer chipset drivers for Windows 7? If some are available, you might try those.
