Problem: System unable to POST. Four LED lights on motherboard ALL RED. No display.
Information: Motherboard is a MSI K9N2 Diamond (See link: http://us.msi.com/index.php?func=proddesc&maincat_no=1&prod_no=1438 ). System powers on, does not POST, four LEDs all immediately RED, no beep code. Hardware (with the exception of the CPU, 2 GPUs, and 2 2GB sticks of RAM, all of which are a little more than a month old) is around two years old with little to no problems until current. Online sources say a LED diagnostic code of: RED, RED, RED, RED, plus a system hang, means that the processor is damaged or not properly installed.
Disassembled computer, inspected processor (looked normal, no bent pins, no burns, etc.), found that one of the pinholes in the CPU socket had been blocked by thermal grease, promptly cleaned the area and then reinstalled CPU. No change in behavior. Tried starting PC with various hardware configurations. Powered on with only CPU installed, then with RAM and CPU installed, then with CPU, RAM, and HDD installed, etc.; no change in behavior. Issue has been consistent through all attempts to solve problem.
Issue(s) possibly related to main problem: Build has 1 DVD-ROM drive (master), and 1 DVD-RW drive (slave). No power is being fed to the DVD-ROM drive (drive tray doesn't open, no life from LED light), tried replacing the drive with another DVD-ROM drive, same issue. Possible that both drives are dead but unlikely. Checked power and IDE ribbon cable(s), everything checked out. Issue first noticed after system refused to POST; previously the drive had worked just fine.
Originally had been a sound card issue (no audio device detected, see thread: http://www.tomshardware.com/forum/294196-28-dead-soundblaster ) which had spawned -- by troubleshooting the audio issue -- the current problem. NOTE: The thread says solved but it was not. I simply closed the thread by selecting a best answer and informing the two members who'd tried to help me that I'd got it figured out. I had not figured it out but did not see a need to keep the thread open.
