My Windows XP system will not wake up after sleeping, and I have to power off to reboot. I'm being told it's because I'm using a wireless USB Keyboard and Mouse? Is there a setting either in Windows XP or in the BIOS that will fix this?

;) get a mac ;)

Windows 98SE, Windows 2000, and Windows XP support wake up from the keyboard but only Windows 2000 and Windows XP support wake up from the mouse. For wake up to work, the keyboard settings must enable wake up from the keyboard.

(Start > Settings > Control Panel > Keyboard > Hardware > Properties > Power Management > "Allow this device to bring the computer out of standby" > OK > OK). Note: Keyboard wake up MUST be enabled for the mouse to be able to wake up the system. (No special mouse setting is required) Note: In some configurations, the system will wake up but the monitor may not come on until the mouse or keyboard is pressed a second time-after the system is awake.

Please rate my answer if it helps...

Thanks for your help! I checked the keyboard and mouse settings, they are set as you described. The mouse and keyboard are set to wake the system from sleep. I guess I wasn't entirely correct in my first statement the problem must be waking the system from hibernation? Set to sleep after 1 hours and hibernate after two. The computer never wants to wake up after it's been of for a couple of hours, blank screen and it will not come back typically I need to power off and on for the system to come back.
