Interesting look at the various waveforms generated by UPS systems

Yes there is definitely something wrong with my computer that freezes.  But I have no idea what or what to do about it.  It's an occasional minor nuisance and has been acting this way for years so I presume it won't get worse.

It's not a power issue, as it might even do it while I am typing a message.  So I hit the power switch, wait the obligatory couple of minutes, and then it asks me if I want to start from scratch or from where I left off.  It doesn't save my incomplete message but otherwise it's not been a serious problem.

I have considered designing and building a UPS but after giving it some thought I decided the need for a battery makes it impractical.  For the same reason I don't use cordless tools; just when I need them I find the battery has expired.  I have about three of them that all need new batteries but my power line driven tools still work every time.  Even my cellphone battery gets run down after a full day of being off the charger.

Try running RAM tests, if nothing wrong shows up, just try setting lower memory clock if bios allows it.

This is off topic but I will try what you suggest if possible.
