I have a Median Composer 5200 system. It runs on a 3.2 GHz Pentium 4 w/ 2x256 MB DDR SDRAM, Nvidia 7600 GS (PCI-E slot), and 200 GB Serial ATA HDD. The issue I am having is that the system will not POST. Upon pressing the power button, the fans run (louder than normal) but the screen remains blank.
I have tried plugging the PC into a known working monitor and the issue persisted.
I have tried swapping in a known working video card (because I noticed that the fan on the card in the PC was not rotating upon power on) and the issue persisted.
I have taken out and and put back in the battery on the motherboard and the issue persisted.
I have reseated each component to no avail.
I have plugged known working headphones into the PC w/ and w/o RAM plugged in to listen for beeps and there were none. It's my understanding there should have been beeps if RAM was not available and there were not.
I have not checked the power supply but I have had it replaced within the last 6 months because the last one had been intermittently failing (PC rebooting) for a while and then it had finally stopped working all together.
I find the motherboard to be failing, but I would like to confirm it or have it contested before deciding to purchase a replacement. If the motherboard be the issue, could someone suggest a replacement as well? I've picked out components and customized PCs before but never have had to pick out a motherboard to fit everything I have and would like input/a point in the right direction.
