My build will start up, then after 2 minutes will stop displaying but everything is still getting power, just not spinning (fans) then after another minute of not displaying it will beep 4 times then pause and beep 4 times again. I've tried putting it on cardboard and it worked longer, but then would crash and say we're collecting data, I then realized that i had no fans beside the cpu fan on it (i forgot xP) Would putting on the cardboard work if i put the fans back? Or do i need a new mobo or whatever? Also i've tried swapping out the ram, graphics card and power supply, didn't work
