Please indicate whether important files are backed up so that a clean install can be performed.

Are you able to perform a clean install?

Then switch RAM modules so that they are tested in the same DIMM. Test the second RAM module for several days and report into the thread whether there are unexpected shutdowns or restarts.

Ok- tried:
ram A in Dimm 1 = system crashed
ram B in Dimm slot 1 = crashed

ram B now in Dimm slot 2: system been running for last 3 hours and so far no crash (and normally crashes lots evening)

so.....let's watch this space

Update: crashed as soon as i posted this. so now trying ram A in slot 2

Please indicate whether you can perform a clean install.

As I said a few times previously i have already done three clean installs and even bought a new hard drive.
Those things did not work. They did not stop the reboots.

I am currently operating in safe mode to see what happens. Does anyone know if i am safe from viruses whilst going online in safemode? I cant find windows defender to check....(only windows defender firewall)

1) Find another computer that you can use.

2) This can take one to two weeks.

3) Please perform a clean install "vanilla type":

a) delete all partitions making an unallocated drive
b) disconnect from the internet
c) make sure that there is no Ethernet or wireless
d) install windows
e) Do not connect to the internet
f) Do not install any drivers
g) Do not install any applications

2) Find a flash drive that you can use to transfer files to a working computer

3) Find a camera or smartphone camera that you can use to take pictures an post images into the thread

4) In the left lower corner search type: system or system control > open system control panel > on the left pane click advanced system settings

a) > on the advanced tab under startup and recovery > click settings > post an image of the startup and recovery window into the thread

b) > on the advanced tab under performance > click on settings > on the performance options window > click on the advanced tab > under virtual memory > click on change > post an image of the virtual memory window into the thread

Right,
You need to goto the BOOT options of the BIOS and make sure Secure Boot is enable. Thats our first hurdle

Pluginz, Can you please explain why? I have two drives (win 7 and win 10) and Secure Boot is disabled. Never had any issues.

Tanya,
Normally shutdowns are related to over heat or hardware problems.
Do you have a temperature monitor?
Open Hardware Monitor
Just extract to C:\Program Files (x86)\HardwareMonitor and run OpenHardwareMonitor.exe with Administrator rights. Under options set "Run on Windows start".
Open your case and check if the heat sink is dust free and if the fan is running normally.
If you have a GPU card, also check the if the heat sink is dust free.

You exchanged your failing drive. Did you do a clean install or cloned the failing drive?
What OS came with your desktop? How did you updated to win 10?
