I have just installed a new Mobo and Cpu the computer wont start (the specs are in my specs bit) I have connected everything that needs connecting but it still won't start. I've also checked for short circuits.
Please could someone help or maybe just confirm that my harware is at least compatible with each other!
What happens:
I press the power button and all the lights/fans come on, even the keyboard lights are on! The Mobo makes the usual startup beeps and whines (I don't think they are beep codes) but nothing comes on the screen! it stays blank and the LED on the screen at red. :banghead:
 
I don't think it is unless it changed in between me yanking it out of the old MB and putting it in the new one. lol
 
you made sure board or nothing is earthing ?
 
Yep, could someone confirm that the hardware is compatible though?
 
Are you 100% sure you connected the 4pin power on the mobo?
 
Yes, could the MB be faulty?
