I successfully installed a HP DVD+RW drive in my friend's PC. Everything was fully operational, but later in the day of the installation, my friend grabbed the PC tower and slid it back across the carpet to return it to its proper location. When he did this, the power cut out. Subsequent attempts to reboot the machine result in no signal to the monitor and no BIOS launch screen. Since I have already attempted to run the machine on a different power supply, I can rule this out and assume it is a failure of the motherboard, cpu or memory (or a combination of these). Is my assumption correct, that to get the initial BIOS screen you need a working motherboard, cpu and memory as a bare minimum? The video card (I think) can not be an issue since it at least is feeding a "visibly blank" signal to the monitor.
Resolving the issue is now wrought with problems. My friend wants to believe that the DVD drive killed his machine. I think that is unlikely. However, the timing of it all leaves me feeling obliged to assist him further. The machine was running for hours just fine up until the time he slid the tower across the carpet. Anyway, here are the problems - I have no way of knowing with certainty which of the critical components is failing (motherboard, cpu or memory). However, instinct tells me to start with the motherboard. I have no way of testing the cpu or memory. Bad news - the motherboard is a 3-4 year old OEM version from Abit and seems impossible to directly replace. What can I do (with the specs from the CPU and memory in hand) to match them to a different, yet compatible and available motherboard? My friend hasn't the money or the will to replace his computer at this time. He just needs a cheap fix to get him back to where he was. It just seems like locating obsolete standalone motherboards for sale is not easy to pull off. CPU is an AMD (not yet sure about the specs) and the memory module reads Centon Electronics Inc 128MBDDR T153625.
I need some advice in a big, big way. Through it all, rest assured I will resist the urge to help out a friend this way in the future. Originally, I just handed him the DVD drive and said "it's easy to install, you'll figure it out". At his urging, I did the deed for him. Stupid, and this is likely to cause a rift in our friendship. He is nearly sold on the idea that it's my fault.
