I'll just list out what I've observed:
-On switching on the system, I get no display and no beep. If I press the button again, it shuts off. I can switch it on and off n number of times and the only way to escape this is to press the reset button. Then the computer functions as it normally does. Then I turn it off and I have to go through the process above to make it work again.
-The system freezes often and I get some sort of delayed response but again I have to press the reset button. The PC seems to work on alternate times. Like properly, freeze, reset, properly, freeze etc.
-Once got the blue screen on start up, but that was resolved.
-Reinstalled the OS (Win XP), but to no avail.
Thanks in advance
