Soltek MBO, 256MB SDRAM, 13.5GB HD, 500MHz CPU, OS WINXP Pro SP2.
PC behaving queerily. When pc boots up to Windows and left unattended for more than 1 minute, the PC freezes . Ctl-Alt-Del not working, HDD spinning and cpu fan working under this condition. After switching off and rebooting, I found out that by running WMP10,PC will work normally.
Your help appreciated.
