This is a custom-built computer for a friend. MSI K9MM-V motherboard, with an AMDx2 64 processor. Radeon x1650 AGP video card, Audigy 2 PCI sound card. 160GB IDE hard drive.
It was working just fine, until I upgraded to the above motherboard, processor, and put it in a new home for him (case).
After doing a typical install of XP (and after starting it, beginning to install some drivers. chipset, etc.), I restarted, and it froze at the motherboard "logo" screen. i unplugged all peripherals (only power and monitor) and it booted just fine. restarted, plugged in an old ps/2 keyboard, started it up, went into the bios, and disabled the "startup screen" thing. restarted with USB devices plugged in, and it freezes right where it says the processor information, "AMD X2 4000", etc. it won't say the next lines (such as what IDE devices are plugged in, it won't go through the RAM validation, etc. it will just freeze right there).
I've looked through the BIOS, but can't find anything to tweak to prevent this from happening. I know my friend would hate to unplug all his devices before starting it up...
what's the problem? any advice?
