The HD seems fine as it works in another pc without incident, I find that when this occurs I have to power the pc on/off several times before the mobo tries to reset to default after which it works fine until the mouse mentioned problem occurs again. I've read through some other forums looking for similar issues and some users have suggested hardware failure but this does not seem the case as the computer runs fine when it starts, even under heavy load, and the occurrence of the cursor issue seems rather random. I tried resetting my cmos settings but it still persists so for the moment my working solution is waiting for my mobo to recognize the problem and hope my pc doesnt crash :/
And no I do not recall changing the bios in any way. After each incident I have reset bios to "Fail Safe Defaults" but it still occurs.
