My frozen mouse again

I have a mouse pointer that keeps freezing. I can still move the mouse around the screen but the pointer stays put.(like having an invisible pointer) not long after the whole system locks up. I have recently upgraded the whole system except for the vid card (asus v8200t2) this is an agp 4x card and should be fine on my mew MB (MSI K6 Delta). I swapped the card for a relatives hercules 4000xt PCI version and the problem went away. My card works flawlessly in the other system (Stoneage k6 500, no ideaa motherboard and xp pro) at moment(till saturday) i dont have access to a more modern vid card. Can anyone explain this to me? Also exactly what settings in bios should i have set for the asus card? I have tried a few different ones and can't seem to make a difference. What voltage should i give the card(set it to auto and agp 4x at moment)there are other settings in there i'm un sure of. I have also tried different drivers this seems to make no difference. I would also like an explanation of just how the mouse pointer system works in windows (tried googling and can't find a search string that brings up relevant results)another wierd thing is that if i run a sisoft sandra burn in on ram, cpu arithmatic & multimedia, file system, memory and cache memory for an hour or two the thing won't lock up at all. stop the burn in and with in 30 mins i get the lock up. I'ts not temp related as a restart will get it running again, this is not enough time to cool anything that was too hot. Any usefull sugestions are welcome. I had the card overclocked in my last system and it ran fine and in this it is at stock.

I used to have the same problem you did. I had XP pro and to fix it I just updated to SP1.
