I posted this in this thread:
Finally, I thought it could have been dirt and heat build up. After cleaning, it worked mostly pretty good for a few weeks.
Yesterday, it shut down and I can't get it to power up at all.
Any suggestions on what and how to test?
I realize that it's hard to diagnose a problem without it running.
There was some speculation in the other thread that it could be a hard drive problem. I have a second drive in the computer. Is it as simple as replacing the cables on the present "c" drive and making the other one the new "c"
I'm guessing it can only be several things.
Power source being another.
Would like a systematic approach, if possible rather than throwing parts at it.
Thank you for your always great help.
