The computer turns on, the fans are spinning and the case lights are lighting up as they should be. However, there is no signal from the monitor, mouse or keyboard. The computer does not boot up at all, it just turns on and that is it.
I have checked that all the cables are plugged in properly, I have tried releasing the stored electricity by switching the PSU off, turning the PC on so it runs briefly for about half a second, and turning the PSU back on and turning the computer back on. To no avail, that does not work. I have also tried unplugging the power cord into the PSU, that does not work either.
Although, I have noticed, is that when I try to hold the computer down for the 5 seconds for a safe shutdown, that doesn't work. When I first installed the PSU, the PC could shut off from the 5 second shutdown sequence, but now it just doesn't do it anymore. I also had a half glance at the keyboard with the lights lighting up, it did it briefly and now there is no signal from my monitor, mouse and keyboard. I cannot get into BIOS or anything, no splash screen or anything comes up, no lights from the mouse and keyboard either. But my Thermaltake Mousepad lights up when the PSU is switched on from the back.
I have also tried unplugging my secondary hard drive and trying to boot with just my main hard drive, that also didn't work.
This is extremely odd, can anybody help me out at all? I seriously need to use my computer for work, and I am a fairly avid gamer, I get seriously bored easily...
