K8 Neo2 Platinum Issues...

I recently purchased a K8Neo2 Platinum while upgrading my system. The new board had some problems, such as BSODs (machine check exception), and the mouse would only work every other boot. Upon updating to BIOS version 1.09, all of these problems went away save one, my PS/2 Optical Mouse no longer is detected. Windows says there is no mouse installed at all. The mouse's laser is lit, however, and unplugging/plugging the mouse back in has no effect. I've already resetted to CMOS defaults. The system is not overclocked. Below are my specs:

AMD Athlon 64 x2 4200+
MSI K8 Neo2 Platinum (NForce 3)
1 GB PC3200 RAM
250 GB Hitachi 7200 RPM HD
80 GB Maxtor 7200
Geforce 6800 Ultra
MSI TV@Anywhere Master
PS/2 GE Optical Mouse
Generic USB Keyboard
 
Try another mouse if you can to make sure it's not the mouses problem. If it still does it with the other mouse the it's a faulty motherboard.
 
The mouse works fine when plugged in to another computer, however i haven't been able to try another mouse because i don't have one.
 
Ok the connector on your motherboard must be messed up, I'd return it and get another. I have the same motherboard as you and have never had any of the problems you have described only problem I have is my ethernet cable doesn't want to stay in but I know that's cause the connector on the cord is messed up. Just noticed you have an X2 cpu The BSOD you were getting was probably caused from you having an X2 cpu and that motherboard didn't support the X2 till bios version 1.9, which would be why it went away with the bios flash. When you get a new motherboard you'll probably have to update the bios again in order to get it to run right.
 
Oddly enough, i just tried linux, and the mouse works fine. It just won't work under windows xp. I'm stumped. I tried add/remove hardware, but i couldn't find an entry for mice.
 
what is even MORE odd is the fact that disabling ACPI fixed the mouse problem, but upon enabling it i lose the mouse again.
 
That's very wierd, I don't have any clue why it would be doing that. I still think it's hardware but maybe some one else might have an idea of what else might cause it.
 
It appears to be a resource conflict. Solving this is gonna be a pain, anyone have any ideas? It doesn't SHOW as a resource conflict in windows, the mouse just isn't detected.
 
erm, that's what i meant, when i typed that i was a little too stressed.

Anyways the problem with disabling ACPI is NVidia's drivers refuse to work once you do so. As a result speeds are dramatically slower.
