Great to know it's not just me - thanks for that!
My xp is 32 bit and my Windows 7 is 64 however both PS2 devices previously worked in the BIOS and now work nowhere - although their lights flash during boot up.
Just to clarify I had them all working great on BIOS 14 and made no changes except RAM and monitor which is when they stopped working.
As I mentioned I spent quite some time mucking about with drivers and Windows until I figured it must be the BIOS - only then did I try flashing different versions but still no joy.
I'm using my USB keyboard right now but would much rather revert to PS2 keyboard and mouse (better quality) and free the USB slots.
Gigabyte, anyone, please?
