Do you have a TV you can connect the PC to via HDMI? When it switches on and the keyboard lights up. Try hitting F1.
Hello Scott, thanks for your reply bud, I called PC specialist this morning and spoke to tech.
He talked me through trying a few things, removing and inserting the card, ram, checking the SATA leads.
He said it's an odd one as it went through an 11 hour test before dispatching, anyway he came to the conclusion it may be the graphics card.
I disconnected and took the card out and plugged it into the Motherboard graphics and the PC worked.
I have a new one coming out to me tomorrow to swap for the old one. If that doesn't work I will give it a go.
Thanks for the comments, appreciate it!
