I'm having incessant dropouts AFTER my computer is accidentally powering off.  And yes I have my music computer on a UPS, but temporary blackouts still cut the power to my computer.  I guess I could get another UPS, but 2 other computers are hooked up to this UPS, and neither one of them power off when this happens.  A friend who is rather Sonar savvy suggested clearing the picture cache might stop this behavior.  Any thoughts on that?  Could someone explain to me how to do this?  I know where my picture cache folder is, but I want to delete WOV files, and most of the files in my picture cache are WTR files.  I don't even know what those are.  Here's the kicker:  leaving the computer and Sonar on for several hours eliminates the problem.  Still we've been having lots of storms, and these blackouts are pretty frequent.  It's disrupting my workflow and day in general.
 
Any help or advice would be oh so much appreciated.
 
Thanks.

Clearing your pic cache will not fix your Drop outs. Drop outs are caused by your CPu not being able to handle the current workload. to fix it, you need to adjust your ASIO buffers or WDM slider. That's all. 
 
FYI: you can clear your pic cache by deleting the contents inside its folder. But this will not fix your drop outs.

Thanks very much for the reply.  Yeah, I've tried all that and nothing works.  I'm just stuck with leaving Sonar on for about 3 hours, then the dropouts disappear.  I'm really flummoxed by this behavior.  I appreciate your instructions on clearing the picture cache.
 
Thanks again.

You should be running chkdsk on all your hard drives straight afterward an abnormal shutdown.
If the UPS is any good you should be able to hook it up to a port (such as USB) and this will notify the PC to shutdown (if configured correctly), if it doesn't do this you need to consider another solution.
 
You might also want to try sfc /scannow on an administrative command prompt to see if there is any corruption in windows.
 
Also please note Windows 8 is much better in these scenarios (I'm not saying it will fix your problem however, your real problem is that your PC's won't shutdown nicely after a power cut).
 
Cheers...

That must be a huge UPS. Generally a home size UPS is designed to handle one PC and the associated peripherals.

What plugins are present?  Some plugins are not meant for tracking, but for mixing/mastering.
 
What driver mode are you using?
 
What sample rate in Sonar?  What are Sonar-reported latency values (input/output/total)
 
What sample rate and ASIO Buffer Size in audio interface?

Thanks very much.  I'm not overly computer knowledgeable.  Recording music is mostly what I do on computers, so I certainly don't have much technical expertise.  I'll be talking to the manufacturer of my UPS to see how I can avoid these power interruptions.  I didn't even know you could hook it up to the computer to make it shut down nicely.
 
Your help is greatly appreciated.

It's got 6 outlets.  I didn't know it wasn't kosher to use more than 1.  I use 3.
 
Thanks.

Thanks Bob.  I'm running no plugins.  I'm tracking the drums.  All the tracks are naked for now.  ASIO driver, 48/24 sample rate.  I don't know how to access the Sonar-reported latency values.  The buffer in my sound card is set to 256.

The owners manual provides information about how much power you can safely draw from the unit. I would imagine you are overloading the unit.
