I recently put together a comp for my mom's business using old parts. After setting up the computer for the first time I noticed that it would not boot up even though the motherboard, cpu, memory, hdd and psu were all fine (atleast I think). The PSU would send power to the motherboard (mb light would turn on) but the computer would not start, no fans would whir. I finally figured out that I would have to clear the cmos memory by taking out the battery for 20-30 secs then putting it back in. Then the computer would power up fine. But I have to do this every time there is ANY change in the hardware like adding a soundcard, moving any wires, even pulling out the power cord from the psu. What is going on!?
