Hi welcome to JustAnswer,Largest Online Q&A Company. My name is XXXXX XXXXX I will be assisting you today.
any error message is coming before it turning itself off ?
no , it just shuts down completely , ie power turns off
ok It is due to CPU overheating ..to protect the CPU system turn off itself
You need to check the CPU fan first after turning on
it is running or not
if it is not then the CPU fan needs replacement ..
you can find any computer hardware shop for replacement fan
and if the fan is running ..then check any dust or blockage around it and remove
if after removing dust same problem then you need to apply thermal paste on the CPU and heatsink
after this your system will not shutdown automatically
the fan seems to running and now that the case is open and the power motor half pulled out , the computer hasnt shut down yet , so is it just dust build up causing this
it is the protection which help to minimize damage to cpu
so if i just carefully clean out the dust inside the computer , the problem is solved ?
thank you , your help good
my pleasure ...don't forget to accept the solution ...
positive rating will be apprecited ..
