I have been facing an irritating problem with my PC. Here is the configuration of my pc
Processor: Intel Pentium Dual 2 GHZ
RAM: 2 GB
32 Bit operating system windows 7 Starter
Problem: After I open my PC after 1 or2 mins it shut down automatically.Then It restarts and after 3 or 5 minutes It again automatically shut down.
Once shut down automatically,If I switch off main power supply button to pc (Without giving it restarting opportunity) and then start the computer again manually It doesnt shut down automatically anymore and I could use the PC as many hours as I want. But next session of starting PC same thing repeats.
I already have changed my motherboard and hard disk twice but nothing is solving the problem.
Whether your computer is just powering off or restarting on you, it could be many different things.
It could possibly be your fan that cools the board is not adjusted properly causing a surge of heat on the board, forcing a shutdown/restart.
If their is no problem with the fan, I would check your power supply, make sure all of the connections are in properly. If you have another computer, I would test that power supply on their to see if you are getting the same problem.
Try replacing the power supply (use one from another computer).
Unplug and reconnect everything on your board (including battery), make sure no wires are broken or look damaged. Make sure everything is seated properly and wires are in good condition.
