Fine , I think it ok , maybe the reboot time could be faster, as SSD disk is in it not that old.

 

photo's goes open with Photos app, and I will check the link you gave to see another default app , that uses lower memory.

 

Thanks a lot.

Let's see if we see anything obvious slowing you down.

 

Get Process Explorer

https://live.sysinte...com/procexp.exe

Save it to your desktop then run it (Vista or Win7+ - right click and Run As Administrator).  

View, Select Column, check Verified Signer, OK
Options, Verify Image Signatures


Click twice on the CPU column header  to sort things by CPU usage with the big hitters at the top.  

Wait a full minute then:

File, Save As, Save.  Note the file name.   Open the file  on your desktop and copy and paste the text to a reply.


Get the free version of Speccy:

http://www.filehippo...ownload_speccy/ 

(Look in the upper right for the Download
Latest Version button  - Do NOT press the large Start Download button on the upper left!)  
Download, Save and Install it.  Tell it you do not need CCLEANER.    Run Speccy.  When it finishes (the little icon in the bottom left will stop moving),
File, Save as Text File,  (to your desktop) note the name it gives. OK.  Open the file in notepad and delete the line that gives the serial number of your Operating System.  
(It will be near the top,  10-20  lines down.) Save the file.  Attach the file to your next post.  Attaching the log is the best option as it is too big for the forum.  Attaching is a multi step process.

First click on More Reply Options
Then scroll down to where you see
Choose File and click on it.  Point it at the file and hit Open.
Now click on Attach this file.

 

Also let's look at the boot log:

 

search for

msconfig

hit enter

Click on Boot tab.

Select Boot Log

OK.

 

Reboot.

 

After you reboot you can go back into MSCONFIG and uncheck the Boot Log option then OK.  No need to reboot even if it tells you need to.

 

Boot log is at:

 

C:\Windows\ntbtlog.txt

 

Please Attach.  If Windows doesn't let you see it then:

Also Right click on the clock and select Task Manager then Startup.  On some PCs the Startup Impact column will tell you if a program is causing a slow startup. (I seem to have broken that somehow on mine)  You can add two other columns ( Disk I/O At Startup and  CPU At Startup)  to help diagnose slow programs:

I noticed in msconfig that in the first tab, general,  is selected: selective boot. I'm not sure if this is due to that I enabled loging?

In the boot log we just have:

 

BOOTLOG_NOT_LOADED \SystemRoot\SysWow64\drivers\SaferVPNmmfilter.sys

 

which we can see in the FRST scan is missing. 

S1 SaferVPNmmfilter; system32\drivers\SaferVPNmmfilter.sys [X]

 

There is a second one with a 2 on the end that does load.  If this is the VPN you no longer use I would uninstall it.  We could just put

just put

 

S1 SaferVPNmmfilter; system32\drivers\SaferVPNmmfilter.sys [X]

 

in a notepad file and save it as 

fixlist

to the same folder where FRST lives then just hit Fix.  That will remove the reference to a non-existent driver.

Probably not a big deal in terms of boot time tho.

 

Speccy says it is running a bit hot.  The heatsink may be getting clogged with dust.  Very common on older laptops.  Let's get a second opinion on the temperatures.

 

http://www.filehippo...nload_speedfan/

Download, save and Install it (Win 7+ or Vista right click and Run As Admin.) then run it (Win 7+ or Vista right click and Run As Admin.).

It will tell you your temps in real time tho the default is to show the hard drive temp in the systray.  You can change it:  Hit Configure then click on the highest temp and check Show in tray.  With no other programs running what is the highest temp you see?  Run an anti-virus scan, play one of your games or watch a video for at least 5 minutes.  What is the highest temp now?
 

We don't really want it to go over about 65 under load.  If it does it usually means either the fan is defective (speedfan should tell you your fan speed so you can see if it is running) or (most likely) the interface between the fan and the heatsink is clogged with dust. The best fix for a clogged heatsink is to remove the fan (not the heatsink or heatpipe) and vacuum out the heatsink.  However on some PCs this is major surgery.  Sometimes you can blow air backwards through the exhaust vent while vacuuming at the input vent and if you are lucky it may clear the heatsink.  Don't do it too long as the fan may overrev.

 

Finally Process Explorer says you have an Interrupts problem.  Normally we like to see Interrupts under 1.4 % and yours says:

 

Interrupts    13.01    0 K    0 K    n/a    Hardware Interrupts and DPCs        

 

This will normally slow things down to a crawl.  Usually this is caused by a bad driver. 

 

You also have:

 

mshta.exe    1.66    148 424 K    144 516 K    8020    Microsoft ® HTML-toepassingshost    Microsoft Corporation    (Verified) Microsoft Windows

 

I'm not sure why this is running.  It is a Microsoft file but we normally don't see it running and it is often used by malware.  I would run MalwareBytes AntiRookit Beta just to make sure there is nothing evil on the PC.

 

https://www.malwareb...om/antirootkit/

 

hit Download and Save the file.  Right click on the downloaded file and Run As Admin then follow the prompts.

 

Back to Interrupts.  Let's try Latency Monitor:

 

Go to

http://www.resplendence.com/downloads

Scroll down to

System Monitoring Tools

and then find

LatencyMon 6.70 (or it may be a higher number if they update)

Click on Download free home edition

Save it then right click and Run As Admin.  It will install and then start the program.  
It will tell you to click on the Start button but there isn't one.  
Instead click on the green arrowhead (looks like a Play button).   Let it run for at least 20 seconds.  Then hit the red box to stop it.

Edit, Copy Report text to Clipboard then move to a REPLY and Ctrl + v to paste the text into a reply.  

Click on the Drivers Tab.  Click on the column header for "Total execution (ms)" once or twice until the biggest numbers are at the top then take a screen shot and post it.  Click on the Processes tab then click on the column header once or twice until the big numbers are at the top.  Take a screen shot and post it.  Screenshots should be saved as .jpg so the forum will accept them.

[HaraMo]

the Latencymon can it run while the malwarebyte rootkit is scanning?

[HaraMo]

Temperature: first time doing nothing: arround 51-52 °C , suddenly without reason processor was going from 30% to 70-80% so temperature went to 58-60 °C.

 

then running a scan and a you tube video with google chrome : 69-70 °C

 

only a scan without video: 61 °C

 

the second time doing nothing : 57-58 °C , could not get it back to 51-52 °C.

 

speedfan does not detect any fan , so can't see the speed. but I do hear the fan making more noise when scan or video is running.

 

malwarebyte rootkit reported: scan finished no malware found.

 

 

I remember no by reading the log from latencymon, I did update the drivers intel and nvidia using the website of intel and nvidia and not acer, as acer did not give any update. I hope this is not a issue?

 

log latencymon

CONCLUSION

_________________________________________________________________________________________________________

Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

Can you rerun Latency Monitor without MBAM, MBAR or BitDefender scans in process? Also do not listen to music or play games or use the Internet while it is running.  Try to stop it after 20 seconds.  That's the standard time I use to see how bad the pagefaults are.

 

Looks like cleaning your heatsink is not too difficult (and if you have replaced the HD with SSD then you know the drill)

 

 

18 screws on the back then another 3 where the DVD was and the whole back cover comes off  (no need to disconnect all of the cables as they do in the video) then two screws hold the fan in place.  (I would keep the 18, 3, and 2 screws in separate containers just in case they are not the same size)  Remove the fan and vacuum the heatsink and fan and reassemble.  If that doesn't help (or if the heatsink is not partially clogged with dust) then you can replace the thermal paste with Arctic Silver 5.  (I use the cleaning fluids that come in a kit with Arctic Silver 5 from Amazon for about $12).  Instructions on their website.

I only had malwarebyte rootkit on that was scanning, nothing else. but this tiem I disconnected all devices, internet:

When MBAR is doing a scan, BitDefender will watch over its shoulder and check each file that MBAR looks at so that's why it appeared that BitDefender was also doing a scan.

 

From the latest Lat Mon scan it looks like HDAudBus.sys is the culprit. That's a Windows driver so probably not at fault.  I found a similar problem where they did everything trying to solve the problem and after 5 pages they updated the BIOS and that fixed it.  https://www.sysnativ...g-noises.22016/

You have a rather old BIOS so I would go to ACER support and put in the serial number of your PC and see if they have a new BIOS for you.  I tried to find one but ACER didn't sell your model in the US so their support doesn't offer any drivers.  I did find a similar ACER model that has a new BIOS and several new Intel drivers:

https://www.acer.com...roduct/7382?b=1

so hopefully they will have something for yours.  Apparently you need at least:

one from 2018/05/25

You currently have  25/05/2017

 

Also I see fontdrvhost.exe on the list of pagefaults.  This usually means there is some corruption in the font cache.  See if you can follow the instructions here:

Will check this once I can.

 

And did you see my responds about: that I updated drivers not from acer website but from intel and nvidia, . Could this be a couase of ?

 

I also experienced sinds actually the laptop was new: that it could not turn on. black screen, even know sometimes it happens, I think especially if in sleep mode. I know disabled sleepmode , don't shut off the laptop, it did not had this issue anymore.

[RKinner]

Doubtful that intel & nvidea drivers are a problem.  That's where I send people when the PC maker's support page doesn't have anything useful.

 

Not waking from sleep is a common Win 10 problem.  Lots of possible solutions:

Checking acer online for latest bios it seems the latest bios is 2017/09/21 version 1.18 , this is the same version already installed.

[HaraMo]

I said that laptop didn't went black for a long time, and today, twice it happened. very strange. I did not checked the sleep issue that you mentioned, but the laptop is not sleeping , the leds are on. there is no sleeping enabled.

 

Ok I just discovered that the schema changed from high  to balanced  (energie). that is why it went to sleep. 

 

So wil check your link.

 

It's just strange that harddisk led is still on.

Too bad there is no BIOS update.  Was there anything for Audio?

 

Search for

device manager

hit Enter

 

Click on the arrow in front of sound video & game controllers.  Find the one that says xxx High Definition Audio  and right click on it and select properties then  on the Driver tab find the date and version number then click on the Details tab.  
Change Property to Hardware IDs.  Click on the top one then right click and copy.  Paste that into a reply.  Repeat if you have more than one. 

 

Then go back to xxx High Definition Audio right click and Disable.  (If you have more than one then disable all of them)  Reboot so we know it is disabled, wait about 5 minutes for Windows to get settled  and then do Latency Monitor as before.  Also give me another Process Explorer log.

 

Finally let's check the HDAudBus.sys file.

 

Open FRST (right click and Run as Admin) then put

hdaudbus.sys

in the FRST Search Box and then hit Search Files.  You will get one file.  Please post.
