Hi, Whenever I open my computer, within 1st 2/3 hours my computer is shutting down suddenly for 2/3 times everyday but after that period it is working perfectly. I checked if processor fan running properly, changed CPU gel, nothing worked. please give me a solution. System config: OS: Win 7 Processor: Dual Core RAM: 2 GB DDR3
Have you scanned for a Virus ? Run Scandisk to check for hard drive errors...Also might be power supply going out.
Unless you can provide us with a BSOD code that could help to try and identify the cause, my opinion is a flaky PSU. There could be another component as well that causes it whenever a certain operating temperature is reached. How old is that system and what else does the system consist of?
@Ghostman, thanks for your solution, i have repartitioned HDD and install windows again and now no shutting down issue!! problem solved..
