Specs: Windows 64
Computer sits over nite. . I begin using and it's fast. . .then after 10 minutes slows way down. . after maybe 20 30 minutes it goes back to fast. . .

It acts like it is loading something. . .but I can't figure what.

Could be something is working in the background, such as Windows Automatic Maintenance, as well as scheduled tasks set by you.

Also if you are on 24/7 do you restart Windows at least once daily or once every other day?

Malware is possible because leaving it on overnight gives the bad guys more time to get hacking.

Always pop back and let us know the outcome - thanks

Check the temperatures internally with HWMonitor and leave it running until it slows down, then read the high and low numbers and post these back since you could be throttling down due to heat.

You have to be a little bit crazy to keep you from going insane.

If it's slowing down because it's busy with something in the background you'd probably see increased hard drive activity. Does the HD LED seem more active?

You didn't say if it's a laptop or desktop but most laptops will slow down the cpu speed to conserve battery power when it's not doing anything. That doesn't sound like your symptoms but it's something to consider.

It's a desktop. . .e machine. . .maybe 3 years old. . . windows 7 AMD chip. .

I've had malware problems but cleaned them out. . . and computer works very acceptably for say 10 minutes after I begin using. . .whether I've closed it down the nite before. . .or just leave it on. . .

Then it seems to act like something is scanning the system. . .It will go to a new site. . .but it may take a minute for the command to execute. . .

after 20 or 30 minutes. . . all seems well. . .everthing works lickety split again. . .

I"ve checked all that I know and can't find anything that is scheduled to run 10 minutes after start up. . .????

If you haven't run these freebies on it then do so (in the order given). They almost always unearth malware that AV programs miss:

AdwCleaner:
http://www.bleepingcomputer.com/dow...
(blue Download button near top - not anything else on the page).
Download and "Save" the file somewhere. Go to the saved file then double click it to run the program. Use the "Scan" button, followed by the "Cleaning" button.

Junkware Removal Tool (JRT)
http://www.bleepingcomputer.com/dow...
(blue Download button near top - not anything else on the page).
Download and "Save" the file somewhere. Go to the saved file then double click it to run JRT. It might appear to have stopped at times or flash the screen but sit tight until it has finished.

MalwareBytes:
https://www.malwarebytes.org/downlo...
Download the free version.
Install and Run the program but before doing its Scan go to "Settings > Detection and Protection" and put a checkmark in "Scan for rootkits". Quarantine anything it finds.

Always pop back and let us know the outcome - thanks

Are these slowdowns ONLY while accessing the Internet?

Do they occur even while you are completely disconnected
from the Internet, with the modem / router shut off?

You say "it may take a minute for the command to execute".
What kinds of commands? In what software? The more
different examples, the better.

well. . . possibly I may have found the solution this morning. . . the computer would totally slow down. . . I would be on the net. . .but it didn't matter what command. . .

I went to task master because everything was at a virtual halt. . .and I noticed that Microsoft Works was running. . . .I have used. . but the software is flawed and I've not used for a very long time. . . .so I closed on task master and all of a sudden all was well. . .

I'll try again tomorrow. . .but now I suspect that it was trying to load Works . . . and maybe did so very very slowly. . .

If you never use it and have another office suite installed, uninstall it ans while you are at it, uninstall anything you never use. If you do not recognize it on the list, Google it and determine if it is something you need. Post it back here if you are still not clear on it.
What antivirus are you using? Some of them (popular ones too) are very poor on efficient use of system resources and can have occasional symptoms like yours though rarely regular like your issue (except some at start up or wake up).
Use Task manager again if you have similar symptoms.
Note that if you decide you need to keep Works, there should be an option for it to NOT load automatically at start up but only when you open it and it should then close more completely when you close it as well.

Is / was Microsoft Works default to load automatically at startup?
