and your PS. As well, though you said no signal to your monitor, did you get any BIOS screens? Any beeps? That your keyboard didn't initialize might offer a clue. Is is a USB or PS2 type keyboard? It could sound as if your PC didn't even POST. Try the new PS with the integrated graphics. If it's OK, add the new graphics card. If your new graphics card has its own power connector, make sure to plug that in. Also, examine the plug for incorrectly seated pins.
To give you an idea of what I was doing, I was upgrading my power supply and graphics card. Installed them both. I connected my monitor to my PC via DVI. Then when I booted it up, the monitor wasn't receiving a signal. Nor was my keyboard (tried pressing caps lock and light wasn't going on). So my friend said I might have to take out the new graphics card, boot up the PC, and disable the integrated graphics card. However, when I put everything back together the way it was (including with the original power supply) it did the same thing. No signal to monitor or keyboard. The PC is not being fully booted correctly. It powers on and everything, but something is wrong. Could you guys help! I hope I didn't screw up my motherboard!
PS: I have an Asus m32cd
