Question about E-Machines eMachines Desktop PC
My computer shuts off without warning. It can happen within a 5 to 60 minute time frame from turn on. Any ideas why?
This problem can be any number of issues.
1. Heat. Make sure the air vents on the tower are free from dirt and debris. Open the side up and, using a can of air found in most electronic departments at stores, blow off the dust on the fan and heatsink which resides on top of the CPU. Also blow out as much dust as you can. If your computer is fairly dusty then this should solve your problem, if not check out the other things.
2. Power supply. Sometimes when a power supply begins to fail, it doesn't put out enough voltage to the various devices inside your PC when under load. Swap out the power supply with one from a know working system to verify.
3. Memory. Remove and reseat the memory chips inside the computer. Download a program like memtest to run checks on your memory.
4. Hard Drive. Sometimes when a hard drive begins to fail, it loses valuable windows files. The computer chugs along up until a point it looks for a file then it kills the system.
Based on the issue you described, I believe it to be a heat issue as the computer is designed to automatically shut down if the CPU reaches a critical temperature to protect the internal components.
