Computer won’t start

As aforementioned, it could be a few things.

You could try disconnecting the graphics card first and defaulting to internal Graphics, to check if that has any effect.
But before you do so, enable the Internal Graphics( HD4200 ? ) via the Device Manager if it is Disabled.
Then switch off and remove the Graphics card physically. Then start up and see if that makes a difference.

You could clean the fans and reapply thermal paste.

Cleaned out the dust inside?

All that I can, it’s hard to get to lot of it.

So connect back to the windows 7 drive, start up then go into devices manager and enable internal graphics card, then back onto new ssd to try windows 10 with big red graphics card unplugged.
Why are there two graphics cards?

No need to go back to Windows 7 drive if you have 10 up and running.
Better graphics performance with the external drive. But we want to check as to which component may be causing the issue. It might also be something to do with the power supply.

I don’t have 10 up and running, that’s the problem it keeps shutting down during the installation.
See post #80 it shows how far I have managed to get which isn’t very far.
Didn’t think I’d see anyone up this early to give advice, cheers

Still no need to put the Windows 7 HDD back in again. Just disconnect the external graphics card and try the install again.

From what I can see, it's an issue with this particular device. Many reports of similar behaviour.

Have you ever run DELL diagnostics? Try restarting and pressing F12 on start-up. Is there Diagnostics on the resulting screen? If so, choose that option and take note of any error codes.

This of course only after testing if the OS installation works without the graphics card

I just looked at the graphics card and tried to disconnect it but saw it was connected to my monitor via hdmi lead so if I remove that I won’t be able to see anything on my screen will I?

Do you have a VGA lead, so as to connect your monitor to the other video connection?

It looks like the vga port is also on the rear of the graphics card

I should add that I don't know if there is a VGA output from the Internal graphics, as I don't have a diagram in front of me.
