Hi, I bought this board like a month or 2 to complete my new PC. I plante to play with the DX10 games, so I want to run on Vista 32 or 64 (the best if it's possible).
 
Here's my machine:
 
- AMD Athlon 64 X2 6000+ (3ghz) at (3.4ghz now)
- Motherboard : Biostar Tforce 570 SLI AM2 ATX DDR2
- RAM : 4 gb of Crucial Balistic PC2-8500 at (2.1 volt)
- Video Card : Evga 8800 GTX (not overclocked yet) with 2 120mm fans 2400 RPM to cool down.
- Power Supply : OCZ GameStream 700 Watts.
- A lots of fan to cool down this machine (inclued a 4000 RPM 120mm fan on the CPU)
- Heatsink : Scythe Ninja AM2
 
This is the important part of the thing ...
 
Some errors are the following : My PC is REALLY slow on Vista 64 bit, sometimes he don't detect all the 4 gb ram I putted in, he mades some blue screen at random times. (CAN'T DO ANYTHING ON VISTA 64, EVEN PLAY DX10 GAMES, TOO SLOW :(
 
We've tryed this PC on XP 64 bit, everything work well. The proof, I made over 10400 on 3dmark06. The PC is fast, all the ram works and video card too.
 
So, where is the problem? If my PC is ok on XP 64, the motherboard isn't broken. My RAM are ok too. Then why I can't fun it on Vista 64?
 
I really need all your help guys, ask friend, anyone who can help me out with this.

Thank you.
