Yes, all or most of those. I downloaded latency monitor. Dpc latency checker v1.40. The green bars are all below the 1st line
Yes to the USB controllers. Yes, WiFi is turned off.
Can I get an 'assumed' answer, please.
Should I be able to record and play back at least a few tracks WITHOUT the noise.
I completely understand a tower would be better, but I've heard/read that towers with win xp with a few gigs ram will get better results than I'm getting with
i7 core/8 thread
7200 rpm 500 g.b.HD
8 gb ddr3 ram

Nothing else on the system is running. No other progs/software... but I can't even playback imported tracks just by themselves OR record one single mic track with nothing else in play mode...just one mic...
I should be getting better performance than this, shouldn't I?

Use ASIO driver mode and increase your audio buffer size until the dropouts stop.

This thread gets confusing and I'm not sure at this point exactly what has been done or not done so I'll just give you a list of how to get started even if you've covered this it might help. 
 
Install the latest drivers for your audio interface from the web site
https://www.roland.com/uk/support/by_product/ua-101/updates_drivers/
 
disable the on board audio and HDMI audio and make sure the interface is working in Windows. 
 
Open Sonar , go to preferences, audio and select ASIO mode , make sure the interface is the playback and recording timing master. Check that all in's and outs are available and checked ( important)  
Open the interface control panel ( ASIO button) and set the buffers at a "safe level" somewhere in the middle for now. 
Insert an audio track , select the Interface input your using and arm the track for record. 
Now set the level of the mike watching both the interface meters and Sonars meters. 
 
When you said all the other tracks went dead that implies you used SOLO and not record. 
 
 
 

I do use the asio driver and have gone one notch at a time all the way to its maximum where it's completely unusable

Thank you cactus for your input. I can imagine with all the replies I'm sending back to the various help, one would not know where I'm at now.
That said, in reply to your suggestions, I've done all these exactly as you said. And no, I did NOT hit solo. That was remedied by preferences sound-on-sound instead of 'comp'. Now I don't know if that was a bandaid/quick fix or not. But I do know what the record/solo/mutes are. I have NOT turned off hdmi audio however.
A few very small things I should probably eliminate. Get a wired mouse and turn off the Bluetooth mouse, and give up the secondary monitor. But the 2nd monitor works so well, so much more room.
I'll keep you posted.
That latency monitor BTW shows an average of around 300 and tops out at 400-500. Well in the green area (if you know what I'm referring to).
I've done the ms configuration and turned off everything, shut down a few things in services.msc.

Do you have your interface plugged into a USB 2 or USB 3 (blue) port?  Some interfaces don't do well on USB 3 ports, especially on Win 7, so if you have a USB 2 port, try that.
 
Can you get audio to play through the interface from another piece of software (windows sounds, a browser, etc.)?

'Do you have your interface plugged into a USB 2 or USB 3 (blue) port?  Some interfaces don't do well on USB 3 ports, especially on Win 7, so if you have a USB 2 port, try that.'

Yes the interface is USB 2.0, going into a 2.0 connection. I have 2 of each. Black 2.0, blue 3.0

'Can you get audio to play through the interface from another piece of software (windows sounds, a browser, etc.)?'

Yes. I have hooked up my Roland vs 2480 standalone hard disc recorder hooked into it.

Question asked earlier: updated the drivers from the Roland site.:
Yes, and oddly, the win 7 drivers are NOT on the units page. I forgot how I found it. It had been suggested using the Vista drivers but it they were prevented by windows to take hold of the unit.
I've tried asio4all. No luck. Worse than the asio

Did you run DPC Latency Checker http://www.thesycon.de/eng/latency_check.shtml or LatencyMon? http://www.resplendence.com/latencymon 
 
The first one is for older OS, like XP or Vista, but supposed to work up to Windows 7, and broke in Win 8.  But LatencyMon should work for Windows 7 and newer.  
 
Sweetwater has some troubleshooting tips here: https://www.sweetwater.co...ng-dpc-latency-issues/
 
The tips for DPC Latency Checker include going through the system device manager and disabling all but the essential devices, one at a time, until the problem is isolated.

Make sure you completely remove ASIO4ALL from your system.  Even if you're not using it, it can still adversely affect performance of the other driver mode.
 
Rather than hooking up a external piece of hardware to your unit, can you get something internal to the computer to play through it, like a Youtube video?

Thank you everyone for coming to my aid. Although I have not found an answer to this issue, I still need to thank you. I have no clue what it could be.
If there were something wrong with your computer you could take it in to get it serviced. Your car~service.
There's a repair service for anything you can think of.
Except this.
Or is there?
Are there places you can go where someone can look over your system and find the bugs/tweak the system?
I'm at a loss.
I've done everything everyone has suggested, and I can't get one single take on a freshly reformatted Sony Vaio i7, 500gb 7,200 rpm hd, 8 gb ram, fresh install of sonar platinum.
I can't get 5 seconds in before snap crackle pop takes over.
Unless a miracle answer shows up, I haven't a clue.
But thanks anyway.
no need to keep at it.
Thank you, really.
