HP Pavilion Elite m9351
Microsoft Windows Vista

Hello, my desktop computer has suddenly decided to not turn on after a couple hours of being left alone.

Here is everything I have done on the computer up to this point:

I reinstalled Vista on the computer from a DVD. I tried to install Service Pack 1. It got to Stage 3 out of 3 100%, and then said that the Service Pack did not install, reverting changes. It then failed to boot into Vista, saying a necessary file was missing/corrupt. I decided to go have a sleep and try to sort it out later.

A couple hours later (2 hours approximately), I woke up and went to turn on the PC, but it wouldn’t turn on. I checked the back of the computer, and the power supply light was not glowing green anymore. I’ve tried a different power cable and plug socket to power the PC with no change.

The computer was working absolutely fine with no errors or instability in Windows before.

Does anybody know what could’ve happened?

My system is a HP Pavilion Elite m9351.uk

Edit: Here is the system in question on HP’s website:hp-pavilion-elite-m9300-desktop-pc-series

@hazzerhendy , welcome to the Community.

 

It sounds to me like you have a failed power supply unit (PSU).  There are many signs of a failed PSU that are not directly recognized as a symptom, such as, apps not installing properly.  I suggest that you test it to make certain before buying a new one.

Thank you for your reply! I didn’t know that a failing PSU could affect software in such a way. Maybe that’s why i’ve been having such troubles getting Vista to work lol!

You are right, it was dead. I have replaced the PSU with another one from a similar system (from a p6109uk model. Same wattage, size etc) and all is working as it was now. Maybe might have some better luck with apps now.

Thanks! Regards
