Computer shuts down on start up before windows installs. I have to start it 3 to 4 times before it finally starts. Essexboy has done all the malware and spyware and this is all clean.
Please help

Did the issue started, when your computer got infected, before that, or after cleanup was done?

[Jeanie_Mcgough]

No it started a few months ago before the computer was infected. But gradually over time is is getting worse.

It may be failing power supply.
Does the same thing happen, when you start in safe mode?

[Jeanie_Mcgough]

Yes,it still does it if you start in safe mode

I think, replacing power supply would be the best first step.
It's pretty easy operation, so you can do it yourself, or with some help from a friend, who knows little bit more about computers.

[Jeanie_Mcgough]

It was the motherboard that was damaged due to overheating.
