[HELP] No Signal

Right, well a few months back I made a thread stating the I get no signal on my Screen when computer is booted up. You guys told me to buy a new motherboard. Got the new motherboad today fitted it, tried to boot the computer, same problem no signal. Changed the RAM around 1 piece didn't work so I took it out, also computer refused to boot with my graphics card inside, so I removed that too. no biggie. Booted the computer, got signal set BIOS and CMOS all fine.

Was on the computer with everything working for about 45 mins, then computer suddenly shuts itself down, try booting again. Back to sqaure one "No signal detected".

I'm ******* livid at the moment just spent loads on a new motherboard for the exact same thing to happen again. What the hell is just breaking my PC?!!?

... you have tried another monitor haven't you?

Yes......... and the leads thats essential. Don't take me for an idiot?
