Question about HP Media Center m7250n (ED842AA) PC Desktop
You have a very tough problem. You need to remove the outside metal to get to the motherboard. Look carefully to see if a card has lifted out of the board connector. See if the fan on the CPU is plugged in and running. If not, your CPU is probably fried. If it looks good, try removing the RAM chips and boot up to see if you get a beep code. This is good if you do. Put the chips back in order and take out an external video card. See if you get beeps ( you may not have this card, it may be built in) See if a lot of dust has collected everywhere and clean it up. try tightening up whatever you can and try booting again with your finger holding down a keyboard key. This should cause an error and a beep code. If it does, try booting normal, going into setup with either esc del or F10. If you get to post you have won.
