A friend of mine asked me to take a look at his computer. He told me that one day he went to turn it on and nothing happened. I tested the power supply and sure enough it was dead. I put a new power supply in and attempted to start up the machine. The fan on the power supply starts, as well as the fan on the processor. The “busy” light on the cd-rom is lit and the light on the NIC card is also lit. The fan on the video card runs and the hard drive light on the case stays solid red. The floppy drive and the hard drives do absolutly nothing. I do not know what type of motherboard is in the system. He has an Athlon Processor (not sure speed) with 2 hard drives, Primary is a Western Digital Caviar 6.4GB and the slave is a Maxtor 20.4GB Diamondmax Plus 7200. The video card is a PNY GeForce 64MB and I am not sure what type of sound card, just that it is PCI. There are also 2 NIC cards. He also has 512MB RAM (2 DIMMS). What could be the problem? I checked all the connections andthey seem to be ok. Could the motherboard be bad?
