I bought this dell inspiron 531 about 2 yrs ago. Last nite, it shut off itself while I was surfing web. First I thought Maybe its virus. I reinstalled windows. it still shut off itself and it gets worse. Yesterday, at least I can see the windows logo shows up, sometimes, If i m lucky I can get into system for 5-10 mins before it shuts itself off.
but this morning, as soon as I turn it on, even before logo shows up, it just shut off.
I checked cpu fan, it still running. so probabl not cpu overheating caused this problem. Is this a power supply unit issue? I gonna order one from ebay, but before I buy it , what else I need to check?
thank you for your help.
I checked my cpu, I notice at the bottom of my cpu fan, thermal glue all dry out. coudl that be the problem? cpu fan still running .
