Macbook Pro not booting well

I have a late 2011 MacBook Pro which is not booting up correctly. When I turn it on instead of the grey screen & dark grey apple logo I get a tonal red colour, then the load bar and followed by a blank grey screen and then it turns itself off!


MacBook Pro 15", macOS 10.13

You can try both:


resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

and

resetting the SMC https://support.apple.com/en-us/HT201295
