(Solved) Desktop pc suddenly slow
« on: February 19, 2016, 02:38:17 PM »
Hi guys,

Everything was going well for a while (SO wonderful  :cheesy:) but since a few days my desktop pc (HP, W7) has become superslow. The weird thing is that it's not all the time, sometimes I have no problems, sometimes after a while, sometimes the whole time. Sometimes a reboot helps but now it seems to be getting worse. It doesn't matter what I click on, it takes like half a minute to a full minute for the pc to get the job done. I cannot play any videos anymore, they're full of hiccups. So it seems a buffering problem?? I regularly clean the pc with WiseDiskCleaner (= similar to CCleaner) and with BullGuard's optimalisation feature. I did several scans (MBAM, Eset, BullGuard) but nothing there.

Anybody any ideas?

Have you checked the BIOS when it occurs to check the temperatures ?

Alternatively, you can leave the free version of HWMonitor running to keep an eye on the temps as the case may need a clean out.

The freebie download link is lower don on the left.

Hi Boggin,

I downloaded the program (don't like entering the BIOS on reboot) and temperatures of motherboard, processors and SSD drive are perfect. Am experiencing no problems with slowness at all today. So I should check the temperatures when it does get slow? And by cleaning out the case you mean literally dusting off the inside of the desktop thing (cannot find a word, haha)? I heard about that. Would be a first for me to open the thing up....

Is ESET your AV program and what is Bullguard ?

If it was overheating then it wouldn't be as intermittent as that, but checking the temps when it does slow down is something to check.

It sounds as if something is running in the background at times and using up memory and maxing out the CPU.

When it's running okay, open Task Manager and under Performance see what the Memory and CPU usage is and under Processes see which is using the most - double click on Memory in that column and they will sort themselves to the highest first.

You can then open Task Manager and compare the results when it starts to or gets slow.

ESET is a free online scanner and is supposed to be one of the best. http://www.eset.com/int/home/products/online-scanner/

BullGuard is my (paid) antivirus & firewall program. Am very satisfied with it.

That was rather cool to see the memory usage of my programs, Boggin!  :smiley:  I made a screenshot so I can compare things. Yes, I agree, it feels like something is taking up too much space sometimes. I thought about that yesterday when I looked at 40 pages on an online webshop site, but I also had the issue in a major way right at startup last week.

Because my problem happens so randomly I don't think this is a cause but I wondered about this. Would you mind explaining this to me? When I load a lot of pages or windows it takes up a lot of cache, right? And that could also slow things down, couldn't it? So if I want to delete the cache, how do I go about that? I assumed WiseDiskCleaner does that as it mentions Mozilla Firefox Cache (see attachment). So I did that when I had major problems yesterday, but it didn't help. I ran the optimalisation feature in BullGuard and it gave a lot of Mbs in the Firefox cache to be removed which I did but that didn't help either. So what's with the cache? Is it a good idea to empty it after several hours at the pc? The Task Manager says the cache now takes up half of the memory (about 4 out of 8 RAM). I hope I'm not saying really wrong things now. I'm out of my league here. :)

Oh, light bulb moment! Yesterday before closing down I closed quite a few windows in Firefox. I now have about 70 open and I closed about 20. Could that just have been it because today everything is peachy!

Another thing: it struck me that EMET (not to be confused with ESET) takes up ranking No. 7 in memory usage. Sometimes I get this message from EMET (see attachment) when I'm working in Word and it closes Word down. Today I had it again when I wanted to open a file which I use daily. On other days I have no problems opening it. After opening Word anew I got the same shutdown on opening that file two times and the third time I opened it via the regular opening button (not via 'recently opened documents') and everything was fine again. This seems to me to be odd too. Do I really need EMET? (I have version 5.2.) I thought it was needed for the Internet Explorer browser but I don't use IE. I was told to install EMET anyway but maybe it is outdated and only interferes? Cannot find any answers online about that.

Hope you're still with me. :)

It has been found that an AV program updating in the background can slow a machine down, but I think the only way to determine if EMET is conflicting with other software on your system would be to uninstall it.

Which browser are you using if not IE ?

Flash Player has recently been found to cause slow in Firefox and changing it to ask to activate has resolved.

Other than using CCleaner to clean the temp file cache which I use, there can sometimes be a lot in the Temp folder which it hasn't cleaned and you can check that by going Start - type %temp% and press enter.

For the most part, the size of the files are listed, but if you want to remove them - click on Organize - Select all - Organize - Delete - confirm - check the box then click on Skip.

There should only be two or three small ones at most remaining.

Unnecessary start up programs in msconfig can unnecessarily take up memory and if you are used to having a lot of tabs open, then there will be competition so to speak.

You don't really need anything in the Startup menu except your AV program if it is listed in there - sometimes it's listed under the the Services tab.

Anyway, go Start - type msconfig and press enter then under the Startup tab click on Disable all, but don't do that until you have uninstalled EMET because if it is listed in the Startup menu and it is disabled when you uninstall it - it will leave orphaned files and that entry will remain after the program has been uninstalled - and this applies to any program that is in the Startup menu.

I think you are confusing EMET and ESET. ESET is an online scanner which can be used whenever necessary and updates at that moment. It is not an installed program and doesn't run in the background.
EMET is a Microsoft tool to help against vulnerabilities in the Windows software.  https://support.microsoft.com/en-us/kb/2458544

I'm still unsure whether EMET is really necessary. An IT person told me to use it. It only conflicts with Word sometimes. I think I'll make a new post just to ask about EMET.

Flash Player has recently been found to cause slow in Firefox and changing it to ask to activate has resolved.

Do I understand correctly that I have to change the Shockwave plugin into "ask to be activated"? I have it on "always activated". Do you recommend Flashplayer over Shockwave Player?

I ran through the Startup Menu a while ago with someone and I only have a few, like AV and Intel.

Today I have no problems with slowness again. Maybe it was just another temporary Windows Little Devil. We KNOW they exist.   :cheesy:

Thank you, Boggin! Much appreciated once again.

No, I wasn't confusing anything.

The AV program that I was referring to that could have been updating in the background was for your Bullguard and then went onto mention EMET and I'm well aware of ESET, having used it a number of times myself.

Shockwave Flash is what Flash Player is called in Firefox, although there is also a Shockwave for Director which I've never understood the role of - while I have both Flash Player and Shockwave in IE.

You could change it to Ask to activate to see if you still get the intermittent slow as it could be one or more of the many windows you have open that is making the demands.

Oh, now I understand! That's a good one anyway, I changed it. Didn't know that open tabs which haven't been opened to use on a new day, if you understand what I mean, are making any demands on the system.

The AV updating seems to me an unlikely cause as the slowness lasted so long while I was trying out things to solve it.

The number of open tabs I can understand. Still, it doesn't explain why on one particular day there was a huge slowness on every mouse click in every program and after a reboot everything was fine..... Really odd.

The pc is slow again, in an increasingly worse way.

How much should the percentage of processor use in Task Manager be, ideally spoken?

I have open: Outlook e-mail program, Explorer, Firefox, Word, Energy Management, Task Manager, HW Monitor.

This is what I noticed: yesterday when everything was fine the processor use varied between 0 and 5 percent. When the pc now gets non-responsive, the processor use drops to 0% (see attachment). That may be obvious to you, but I don't know, maybe that helps. Is 0 to 5 percent not very little when it functions normally?

If the machine is frozen then there won't be any CPU usage, but something is using up to 3.02GB of memory.

Out of the 8GB I have installed, with my gmail, the forum and Task Manager open - while the CPU fluctuates, mine is only using 1.72GB of memory.

In Task Manager (if you can open it), check under Processes tab to see what is using so much memory - in that section double click on Memory and it will list the processes from the highest users.

If you have Windows Repair installed, you can use the system tray icon to Clean Memory which may knock the overall usage down a bit.

I'll let you see the Task Manager of yesterday when everything was superfine and the one of right now. See attachments.

The striking thing is that yesterday the pc was asking much more of CPU memory. This was before I closed the 20 tabs in Firefox, I think.

I've noticed that you have the GWX.exe running - don't know if that is significant, although it isn't hogging any memory but go into Task Scheduler by typing that at Start then press enter.

Click on Task Schedule Library - Microsoft - Windows - Setup - GWX and then look at the Triggers etc. to see how often it's set to go looking.

I'm not sure how EMET works but an AV program can slow things when it starts checking files or the tabs.

Have you ever had the slow with say just one or two tabs open ?

I would think your Paging File is set to default but when was the last time you defragged the HDD if you are using one and not a SSD ?

Dear Boggin, I'm late in responding, sorry, I have a lot on my plate at the moment.

The GWX I don't really understand but I can give you two screenshots of (I believe to be) significant pages. It seems to me that it doesn't do a whole lot. I have no idea. Or should I open GWXTriggers?

I'm not sure how EMET works but an AV program can slow things when it starts checking files or the tabs.

Yes, but it doesn't explain why the slowness is so random. I had it again yesterday in a major way, tried to find a possible cause, but had to reboot and everything was fine again.

Have you ever had the slow with say just one or two tabs open ?
It has been a looooooooong time since I had just one or two tabs open. :cheesy: They're my modern form of yellow post-its, you know.  :smiley:

I would think your Paging File is set to default but when was the last time you defragged the HDD if you are using one and not a SSD ?

I cannot find out what a paging file is. My C: drive where the Windows files are on is an SSD.

Tell me if you want some more info on one of these things.

Another problem: to fill in a form for a certain website I have to use Internet Explorer, but I cannot get it to open. It opens but the waiting symbol (the little blue circle spinning) is there and then it shuts down. In the attachment the files that are involved from the error popup.

Maybe it's time for a Windows Repair All In One. Or would that be a problem with my Dynamic Discs?  :omg:

GWX is Get Windows 10 and I was wondering if it was triggered to go looking for the update at certain times.

You can also check to see if Bullguard is also tasked to perform certain actions at given intervals or any of MBAM.

An intermittent fault is the worst type to try to nail down.

The Paging File is your Virtual Memory and you can check to see that it is set for Windows to auto manage it but with 8GB RAM installed you probably wouldn't need it.

http://windows.microsoft.com/en-gb/windows/change-virtual-memory-size#1TC=windows-7

However, I noticed from your Task Manager/Performance that you have very little free memory left.

While I may only have up to 10 tabs open but generally a lot less, below is my Task Manager/Performance and I also have 8GB RAM installed.

I also have IObit Uninstaller and the free version of MBAM - but not Exploit, but don't have them running in the background and have disabled MBAM in services.msc

When you are talking about "slow" is this primarily browsing ?

This can occur when the SNRM drops which affects your bandwidth and could be an explanation for it being intermittent if your computer still performs normally with multiple tabs open at other times.

Would you say that the slow occurs at peak times or isn't there any pattern to it ?

At these times you could run a speed test from www.speedtest.net to see if you are getting what you normally or should be getting when all is well.

You would need to log into your router to check the SNR Margin at these times and if the Downstream is well under 1 then first have a look around your home to see if anything is coming on that could interfere with your broadband signal and checking to see if you still get the slow or not when Ethernet wired could point to fluctuating broadband.

Depending upon your answer, I'll go into more detail on improving your wireless signal.
