Scenario - mum's pc was playing up.

I turn up, run spybot, midway through I notice windows has a thing to sort with kapersky through windows defender thingy.

I click and pc turnd off. Reboot twice, turns off as soon as it logs into windows each time with no error codes.

CMOS shows correct time so not battery, memory all reseated correctly.

I'm thinking power supply as it's an easy cool one about 10years old.

I have a spare antec I can chuck in.

Am I correct?
 
Swapped it over. Boots up but now goes to recovery screen.

It says:
RECOVERY

your pc/device needs to be repaired.

The application or operating system couldn't be loaded because a required file is missing or contains errors.

File:\windows\system32\winload.exe
Error code:0xc000000e

You'll need to use recovery tools blah blah

Press Enter to try again.
Press F8 for startup settings."

What's the issue now?
 
What version of windows is this?

If it's as old as the power supply we're working with Windows 7 - use your windows install disk to access recovery mode, and run CHKDSK /R in the terminal to check & repair system errors.

It's possible the power supply has corrupted something on it's way out.
 
Win 10 with no disk available.

All sorted now, I went through the connectors again and one was loose because the power connectors had pushed in weird and hard drive connector on SSD wasn't in right as a result. All sorted and working now.
 
It was all sorted - received call yesterday it had broken. Meaning we checked out a perfectly good psu.

Thinking next it could be memory so ran windows diagnostic check - nothing wrong with memory.

Memory ran fine, safe mode it was fine.

As it's happening as soon as it boots into windows I'm thinking software issue. Something is loading causing a conflict.

Was thinking maybe motherboard but it stays on in safe mode but doesn't allow you to uninstall things because Windows installer is not loaded.
 
Does it reboot when starting windows or switch off ? If it reboots then you have a blue screen occuring with auto reboot hence why you cant see the blue screen. Usually only recourse is to reinstall windows if you cant get into safe mode and do a system restore.
 
It switched off but when I click restart it just turns off anyway.

I was afraid it would be a Windows fresh install because she doesn't have Windows 10.
