My Hp Pavillion was exhibiting symptoms of a dying power supply--it would boot but only stay on for a few minutes, then flash morse code that it was dying.
So I got a new power supply (LONG painful story for another time but avoid buy.com unless you KNOW you won't have to return anything!!).
I installed it and it seemed to be working, well it sounded like it was but nothing was appearing on the screen. So I unplugged the flat screen from my ATI All-in-Wonder and plugged it directly to the supplied video plug (after removing the card, of course). It still didn't display anything but the power light stayed on the the drive access light flashed.
Plus, now my CD drive won't power on. The DVD drive works, in that I can open & close the door so I know it's getting power, but not such with the CD/Burner. And yes I tried trying different plugs to ensure it's not the power supply.
So I started unplugging the power from different components to see if it would boot just from the mother board--I mean I should at least get to see the BIOS right? I unplugged the CD drive in case it thought that it was dead & wouldn't boot since it couldn't find it.
I asked for help and was told to try removing the battery and checking the CMOS jumper. Well, I removed & reinstalled the battery but never did find the CMOS. Now I don't get anything!!
All that happens now is that the power light comes on!
Prior to replacing the power supply, my PC would get very hot--so hot that I'd burn my leg on the side so I removed the side panel to try to help cool it down.
Obviously, I am really stuck and am in desperate need to have my PC back.
I'm a mainframe gal and just an end-user on the PC! :icon_mrgreen: I can add & have added hardware and was under the impression that replacing the power supply was "no big deal".
