KR7A: mouse pointer flickers between hourglass and arrow with FSB over 143mhz. Why??

[moocat]

Everything works just fine and the system is stable. The mouse pointer just flickers constantly when FSB is at 145-150mhz (I haven't attempted any higher). I've used two different mice, a ps/2 and usb and both exhibit this behavior. They are both Logitech so maybe it's a driver issue (kinda doubt it since there are likely lots of overclockers using a logitech mouse). I posted this a while back but only now have had opportunity to try a different type of mouse interface. Since the problem remained I thought I would repost. Apparently I'm the only person experiencing this problem (at least with a otherwise stable system). I've never experienced lock ups or other abnormalities with either mouse. The system is stable at 150 fsb but I generally keep it at 140 since the flickering pointer is highly annoying.

I welcome any suggestions.

Heres my system:

KR7A (non-raid)
Tbird 1.4@1.53ghz
2x256mb Crucial pc2100
Radeon 8500 oem
Audigy oem
cd, cdrw, and 2 7200rpm HDs
USB zip, modem, and optical mouse
Window98SE

Am I really the only person who's ever encountered this?

Have I stumped the panel? 🙂

You're not the only one. I had this same problem with a Logitech cordless mouse connected to either USB or PS/2 on an 8KHA+, even when not overclocked. I traced the problem to the USR internal 56k modem and the mouse not playing nice. I still have no idea why this happens. I haven't been able to solve it except to remove the modem.

Please let me know if you figure it out.

I've got an external USR 56k USB. I've removed the hardware and the problem didn't go away. I've never tried completely uninstalling hardware and software for it though. I'm gonna do some more experimenting tommorow.

I'm just happy to hear someone else has at least seen this problem.


Thanks.

Check to see if the com or usb ports the mouse is on are sharing resources with another device.
