Ok, multiple issues with my PC. Configuration : P4, 845 GV motherboard, bios version VA84510A.8GA.0023. P08 1. It switches on directly on stwitchin on the mains(without having to press the power button on the CPU) 2. On turning it on, it displays the message : "CMOS/GPNV checksum bad. CMOS Date/Time not set" (changing the battery didnt help) 3. The monitor(SAMTRON) keeps giving the message "Control lock locked/unlocked" intermittently. 4. Also get"CPU was previously shutdown due to a overheating issue" message, once in a few days. I have 2 Hard disks - 40GB Samsung(Primary) and a 250GB Seagate(additional) I installed SpeedFan and it shows me that the the seagate hard disk gets heated very fast, often reaching 50 deg celcius withing an hour or 2.
