i have no idea but is power supply ok wag but thats only thing i thinking
My daughter's XP Home computer (with SP2 successfully installed) and, for the most part, regularyly scanned for spyware and innoculated (spyware blaster, iespyad and hosts) is acting funny.
Start Menu appears, but doesn't respond to clicks, nor does the quicklaunch toolbar. The only area that responds is the notification area.
Only fix is to power down and choose 'last known good configuration'. Rebooted, ran a battery of (spyware) scans, no problems found and now the problem re-appears.
