Windows xp will not load to the desktop, infinite reboot loop

[bydesignmgd]

System:

I have an AMD Athlon 1 gig processor, Gigabyte motherboard, 512 of DDR ram and a Matrox dual port agp video card.

Problem:

System started rebooting for no reason, usually when I plugged in my digital camera into the USB port. Now I installed a new graphics adapter, a MATROX MILLENIUM G450 DUAL HEAD 32MB. The system locked, so I had to cold boot. Now everytime I boot the system it brings up the Windows XP start screen and then attempts to go to the desktop but then I here some kind of click and it reboots my system. Basically it's in an infinite reboot. It says do I want to load original configuration or start normal or safe mode. I've done all and still it keeps rebooting.

I attempted to boot from the WinXP Pro installation cd for repair or re-install, but I got an error message while it was checking my system configuration. Basically it said:

file\i386\halacpi.dll could not be loaded. The error is 32768. Setup cannot continue. Press any key to exit.

I'm not if this is hardware, Bios, OS or what. I would appreciate any help on this problem.

Thanks in advance,

if you can enter Bios see if you have ACPI turned on if so turn it off??

don't know if that will do it so post back let us know.

Thanks for your response.

On my BIOS it only allows me to change to either S1 (POS) S3 (STR). I also disabled all that I could in my power mgmgt. settings but I still get a reboot loop going.
