Lately my computer has started giving me this wierd problem.
My problem:
It goes into shutdown after some time. This happens any time - from within the first 2-3 seconds after hitting the power button to after windows has fully loaded.
Sometimes after such shutdown it reboots automatically after a random interval. the interval can be 3 seconds to 3- 5 minutes.
Sometimes after such shutdown, no matter how many times i hit the power button the system won't start. There is no green light. At these times i pulled the power cable and attached it again, then hit power, then the CPU kicks in. (although no guarantee it will complete a full boot).
What I have tried so far
I cleaned my system for dust so the CPU fan and the power supply fan aren't clogged and they are spinning as usual. But the problem is not solved.
I removed all but necessary peripherals. Earlier I had 3 HDDs and 1 DVD. Now i have just the main HDD.
I took out the heat sink, and I think the thermal paste is worn out. I say 'i think' because i don't know what it supposed to look like. Also the thermal paste felt more like graphite.
My cpu temp is 45-47 degree celcius (abt 112 F). voltages are within 5%.
I replace the motherboar battery with a new one.
I deducted that this is not a virus because a) the problem occurs even while i am in the BIOS config screen (i.e. before os is loaded). b) problem occurs with out any HDD atached. c)shutdown /a does not work because it says that system is shutting down and cannot initiate the process. (i read that this was one of the ways to counter blaster)
I suspected something wrong with the power button spring action, so i manually simulated the power on off with the power wire that goes to the motherboard. no results.
I tried booting my comp with the 3 different bios jumper positions a) normal b) config and c) recovery. no results.
I dont suspect OS issue, because this happens before OS is loaded.
My system
P4 2.4 ghx, 512 on chip, 533 mhz
intel mobo i think DG845gebv2
2 ram modules - 1 GB and 256 mb. different vendors and possibly different speeds i think. (dont think this was a problem, because it worked like this for a year.)
Win XP
Un branded PC, I had bought the parts and got a technician to assemble it in 2007.
my monitor is plugging directly to the wall for its power (i.e. no monitor load on my psu)
What do i do? Please suggest, as this is so frustrating.
