Cpu

My "system interrupts" is using 25 to 35% of my CPU. The article I read said it should only be using 1 to 3% and sometimes as much as 7%. And that it could mean a driver or hardware failing? How can I check to see where the problem is?

What program are you using, that shows that 25 - 35% CPU usage reading?


Also....
Try running the system in Safe Mode.
Then check the CPU usage.


You may have something running {unknowingly} in the back ground.

The only thing, other than the Hard Drive using a lot of CPU time, could be your Video Card, if your running a graphic intense game.
Or doing something like CAD-CAM, where rendering an object takes a lot of CPU time.

Now for some strangeness task manage performance meter is back to normal between 0-3%. procexp64 is showing CPU at 98-99% with system idle process. And now I have no sound. Everything says it's working fine but still no sound through speakers and yet if I put my head set on I can hear sound.
I haven't been able to boot up in safe mode. In fact this all started due to my inability to boot up at all not even with my window's disk. To get a better idea of whats been going on you should read my post in malware removal.

Okay kuzzz,

Get a Stand Alone Copy of Linux.
Either install it on a USB Thumb Drive, or CD\DVD Disc.

In the BIO's Settings for this machine.
Set the First Boot Device as USB or CD/DVD Drive.

Then try booting from that.
If your system boots up and everything is working...
{Audio, Video, Keyboard, mouse, Etc....}

Then I think you have an issue with Windows being corrupted,
and you need to pull off any files you need too save.
Then do a re-install of windows.

If you still have issues with the system, after trying the Stand Alone Copy of Linux.

Then you have a Mother Board problem, since audio chips are on most Mother Boards now.

If this be the case....
Break out your warranty, and see if you can get a replacement.
Otherwise, you'll be forking out the cash to replace that Mother Board.

Go look in the Linux Section here: https://www.cybertechhelp.com/forums...ad.php?t=49057

Also,
Here's a video on how to make one, using an Android OS "Remix OS", and putting on a USB Thumb Drive.

I'm not sure I can get into my BIOs. I can't even get into safe mode. I have my machine set for first boot CD. I have downloaded debian linux. It's a zip file. Do I just export the files to a cd? And then boot up on it? I'm a complete novice when it comes to linux.

Thanks kuzzz

I can restart my computer but if I power it down completely I'm not sure it will boot up.

kuzzz,


Here is a site that will help you understand how to make a DVD or USB bootable Live Linux Drive.

http://www.fascinatingcaptain.com/pr...e-linux-drive/

Watch the Video, and or read and follow the directions on the page.

Note: The captain likes to use "Ubuntu", Elementary OS, and "Linux Mint".

You don't need to power it down.
Just Do a Restart, or press the Reset Button on the system, {If it has one}.

If your computer is suffering from high CPU usage and the culprit process is called “system interrupts”, then you are dealing with a hardware or driver issue.

To quickly check whether you’re dealing with a driver issue, you can run the DPC Latency Checker. Deferred Procedure Call (DPC) is a process related to system interrupts. When the interrupt handler needs to defer a lower priority task until later, it calls on the DPC.

DPC Latency Checker was designed to analyze whether your system can properly handle real-time audio or video streaming by checking the latency of kernel-mode device drivers. It’s is a quick way to reveal issues and the tool requires no installation.

If you see red bars, i.e. drop-outs due to high latency, something is off.
