Symptoms
Upon startup or waking from sleep the computer will not beep, not POST, not display. The fans and HDDs will spin up though. This happens randomly but is getting more consistent. Before I would be able to hit the reset button or hold the power button (which would curiously restart the computer the second I let go of the button instead of shutting it off completely), but as of late those buttons do nothing, nor do the power and reset buttons on the board itself. I end up having to switch the PSU off, wait, and the flip back on.
Its almost like starting an old car. After a few attempts it will finally POST correctly. So I started troubleshooting. Extended MemTest, booting with nothing connected but the CPU and one stick of RAM (tried both sticks as well in case a "pairing" was necessary), clearing CMOS, etc... But nothing was helping. So thats when I started slowly replacing parts.
First the video card (by choice) back in 2012. Still happening.
Then the RAM (figured it was the easiest to go) earlier this year. Still happening.
The the mobo (a lightning storm actually fried it completely) right after that. Able to boot but the same random symptoms are happening.
Well over the last few weeks I have been experiencing very random issues in the OS itself:
* The system time will randomly slow down (syncing it again will correct it)
* My keyboard's repeat rate is much slower and is very delayed to start when holding down a key.
* Chrome is having issues having multiple tabs open with Flash/Shockwave (getting error popups asking if I want to kill the pages or wait).
So I picked up a new PSU in hopes that power was the issue. Last night it was working just fine (all the above symptoms went away) but today I am back to square one.
Now the only thing I might be forgetting is the CMOS battery. When I purchased the new mobo I swapped the batteries and tested the old mobo one last time to see if it would boot (it did not), so I trashed the old battery (5 years is about the avg life expectancy of those things I believe) and used the one that came with the new mobo.
Could the battery be a possible cause of these very weird issues? Any other suggestions on what to try?
Sorry for the novel, I just wanted to make sure I included everything I have tried over the years.
