Win7 works smoothly, then Suddenly slows down.

[Drewseph]

This is a screen for what I see. Sorry I am a noob at this computer stuff >_>

That clean boot link you sent me tell me a bunch of settings to change. will it be easy to revert them back to normal?

 

[richc46]

Clean boot, you untick the box. When done you tick them again

On task scheduler, in the left pane click on the various categories. You will see the schedules in each.

Zero hour came. The computer still slowed down. No abnormal processes were being done and no cpu increases were detected. I let it run until 12pm today until I restarted (had to force reboot)

I ran another maleware scan on spyware doctor, and the other maleware program. both were negative.


EDIT:

Investigating the logs....

An hour before Zero Hour:
Activation context generation failed for "C:\Program Files (x86)\Common Files\Adobe AIR\Versions\1.0\Adobe AIR.dll".Error in manifest or policy file "C:\Program Files (x86)\Common Files\Adobe AIR\Versions\1.0\Adobe AIR.dll" on line 3. The value "MAJOR_VERSION.MINOR_VERSION.BUILD_NUMBER_MAJOR.BUILD_NUMBER_MINOR" of attribute "version" in element "assemblyIdentity" is invalid.


When stuck in shut down:
A timeout (30000 milliseconds) was reached while waiting for a transaction response from the sdCoreService service.

Lets think about this for a minute, together.
Every night at the same time

Has to be something running in the computer or
Something external affecting it.

We did malwarebytes
Antivirus and both an negative
You say that no process began to run at that hour

Im at a loss
Those are the only possiblities.
A malfunction happens anytime.

Put it in clean boot state for the entire period that the problem occurs.

 

[Drewseph]

=( I'm really just worried. My computer was made by PowerSpec. Maybe they have some sort of program running at that time? but that would be detected with maleware. gah this is so frustrating.

Do the clean boot tonight

 

[Grimmjow]

Before doing clean boot, physically disconnect your PC from net. That way you'll determine is it something external causing the problem or not. And way are you sure that the trojan detected is false positive? Are you absolutely sure about that? Do google search for it, or upload it to VirusTotal - Free Online Virus, Malware and URL Scanner see the results

About this:

Activation context generation failed for "C:\Program Files (x86)\Common Files\Adobe AIR\Versions\1.0\Adobe AIR.dll".Error in manifest or policy file "C:\Program Files (x86)\Common Files\Adobe AIR\Versions\1.0\Adobe AIR.dll" on line 3. The value "MAJOR_VERSION.MINOR_VERSION.BUILD_NUMBER_MAJOR.BUILD_NUMBER_MINOR" of attribute "version" in element "assemblyIdentity" is invalid.

You may want to uninstall Adobe reader, and try one of this:

Foxit Software - Foxit Reader for Windows

Tracker Software Products :: PDF Creation Software, Free PDF Viewer
They are great, fast and FREE pdf programs, and widely recommended from members of this forum and around interwebz
cheers

 

[Drewseph]

Thanks I'll be sure to give these a try tonight

Just a thought:

If you have automatic Windows updates turned on, this is the time of day it is normally set up to take place and can be delayed by rebooting. I have noticed the same effects when "automatic updates" are being made, particularly on the first hours of the update dissemination to millions of computers. The automatic updates often make everything slow as molasses in the refrigerator. Also, the "automatic" update takes forever.

Next time you notice, do a manual update of Windows...

 

[Drewseph]

how do I turn this off?

EDIT: Zero hour came early today. 5 after midnight, and 10 min after a fresh reboot in clean boot mode..... everything came to a crawl.

 

[richc46]

Windows Update - Windows Automatic Updating - Vista Forums

Same as with 7

If you are going to try without the internet tonight and it does not work, dont forget about the clean boot.

Up dates are not every night, as suggested by your problem

 

[boohbah]

In start search ,type windows update,then in the update window on the left there is a change setting link in there ,change the settings via the dropdown that gives you the option. by important updates.

Edit: Richard lightning fingers beat me to it.

 

[Drewseph]

I decided to clean boot anyway. I restarted at 11:55. at 12:05am the slowdowns struck. Eerything came to a crawl. Yet my damn resource monitor showed NOTHING in terms of extra processes.

I could not shut down normally... yet again. I had to reboot by holding the shut down button on my case.

is there any way to log every damn thing my computer does?

 

[richc46]

This is like a soap opera.
Try the advice, tomorrow about disconnecting from the internet. Im sorry I did not think of that one. It has potential.

You can type event viewer in search to look for any errors or problems
There is a log that will give complete computer activity, but I cannot think of the name. I will post when I do, .

 

[Drewseph]

I actually pulled the plug on the net the second the slowdowns happened. They continued for 30 minutes until I shut down by force.

Since then I have restarted, updated windows .NET framework, and ATI drivers and turned off automatic checking for updates......

lets see what happens

 

[AllThumbs]

try deleting all cookies and LSO files!

 

[Drewseph]

I always empty my cookie folder. as for LSO, what is that exactly?

 

[Drewseph]

well, Sorry for the double posting. thought I'd update that there was no Witching hour last night. I am not sure if that's because I turned off updates. or updated to the most recent .NET

I'll report back the next time this occurs

 

[AllThumbs]

LSO and cookies

LSOs are files that have been acquiring as bad or worse reputation as cookies. They are usually from use of various products requiring Flash content. See the following links (hope you can take the verbosity):

So it happened again. I was able to get a screenshot of my recourse monitor window.

Left: NORMAL state, I restarted, and idled for 60 seconds and took a pic

Right: is during the system slowdown
