Hello,I have recently upgraded my psu in my system from a 400w to a 750w (plus 80 silver) because my pc would crash when playing games from a lack of power. However after plugging everything in after installing my new power supply,my pc will not boot.. the display has no signal,the keyboard does not respond but all the fans and peripherals in the pc are on as well as the LEDs.
I have tried reseating the ram and then using only one stick (out of the 4 sticks of 8gb that I have installed) in both channels.. nothing
I then tried resetting the cmos by taking out the battery and using the jumper and still have the same problem.
I also tried without the hard drive plugged in and also without the gpu installed and still not booting..
I then tried to hold down the power button for a minute with everything unplugged (externally) and I still can't get it to boot.
At this point I tried using the old psu and it does not boot with the old one either..
I am lost. Please help
