After cleaning the dust out from my PC with compressed air and cotton buds I reinserted evberything and switched it on to find no signal through my HDMI monitor.
To check it wasn't the HDMI I left it for a while and tried pressing the number and caps lock on my PS2 keyboard, this did not change the lights. I tried rebooting and this did not change anything. At the start my keyboard lights flashed but nothing after that.
I then proceeded to do 'all the checks' I reinserted all the cables to check they weren't loose, I tried taking my graphics card out then my HDD then my CDD then my RAM then my CPU doing tests each time. This did not create any bleeps.
A thing I noticed was when my CPU was plugged in I could switch off my PC with the button but with it out I could not. Also with my PATA CD drive plugged in the HDD LED flashes but if just my SATA HDD is in it does not. I have not re-socketed my CPU yet as I have no spare thermal paste yet.
I really do hope you can help, thanks.
Kyle.
 
Solution
check for the bent pins in motherboard or processor. Take your motherboard out of case and test it. Check the back and front of the motherboard closely and look for anything unusual. Also, clear CMOS if that makes any difference.

You're a life saver, cleared my CMOS and reseated my CPU, I think I had screwed on my CPU fan a bit too tight but luckily no permanent damage was done. Back up and running at full speed!
Thank you so much!
