Michael, A couple of questions. First, is this a serial or PS/2 mouse? Second, is just the mouse freezing, or the entire system? If it's the entire system and you are having to do a cold-boot, that could be a different issue than just the mouse. If it is the system itself that is freezing, I would bet that it is a heat problem (I'm not laying odds, this is just conjecture at this point). I had a problem with a 233MMX system that was similar in nature to what you described, and it had to do with the bus speed I was running my processor at. It was too high, essentially overclocking the chip, and the chip was getting too hot and eventually locking up on me. Like you, it could be five minutes, an hour, or a day. But it would eventually happen. Keep in mind, this was a Cyrix chip, so it had a predisposition towards overheating already. But, dropping the bus speed down a notch fixed the whole thing, and the system still runs like a champ today. If just the mouse is freezing and your are still able to issue keyboard commands, I would begin to look at the mouse controller as a possibility. If you have changed mice, we can pretty much rule out the possibility of it being the mouse hardware. On the controller side of things, this could be either in the driver or the controller itself. Did new drivers get installed with the new mouse? Either by you or by Windows autmatically detecting a different mouse and loading different drivers? If not, then I would try removing the mouse (all instances if there is more than one) out of your system settings. Do this in safe mode and then reboot the computer and see how long it works after the mouse is redetected and drivers reloaded. The other option is that it is the hardware. If this is a PS/2 mouse with an onboard controller, try using a serial mouse. If it is a serial mouse already, the only thing I can think of is to get an add-on card for your system to install a PS/2 mouse and try that. This would tell you your comm port is bad. Alternatively, there could be an IRQ conflict on your comm port, and simply changing to a different IRQ in the CMOS might fix it. Hope this helps. Good luck.
