Can't boot
I'm new to this forum and hope that someone can help. I'm fairly computer savvy and do most maintenance and repair on our small office computers. Both are HP P7-1202 with 6GB memory and a Seagate 7200.12 1TB hard drive. My problem is that one of the systems won't boot. It has been acting funny (stopping, sometimes screen flashing blank) for a few days. I thought the hard drive was failing, but I was able to get it running yesterday and bought an external drive that I was going to mirror using the Carbonite software to do so. It failed again, however, and I can't get it to boot again. The hard drive sounds like it is spinning up and the drive indicator light flashes for a few seconds, then nothing.
I swapped the HD with the one in the other system and it booted up just fine. No HD problem, I guess. I had also run some HD diagnostics yesterday while it was running, and no problems were detected. I then swapped memory modules and again no problems. No matter which drive or memory modules I put in the "bad" system, it will not boot.
Could this be a power supply or motherboard problem? I've never encountered one of those problems in the many years I've been working with PCs. I haven't swapped power supplies yet, but plan to.
Any suggestions?
