Win 7 Slowed WAY down

[Pete491]

Guys,

I am having a problem with my PC that maybe you can help me with.

Yesterday all of a sudden everything slowed WAY down. It would take 2-3 minutes for the system to respond to anything. Resources were at 75-100%. A problem like this is hard to work on when it takes so long for anything to happen.

I went in to msconfig which took five minutes to load and deselected all startup programs and rebooted. Everything looked good. System resourses went down to 2-5 %. I went into Explorer to check my e-mail and everything was working normally at first and then the system slowed down again.

How to solve this? It's hard to try different things since it takes so long for anything to happen.

Something is loading that is causing the problem. How to find which one? I hesitate to end programs since I am not sure which ones do what.

I have Win 7 which has been working great for over a year.

I just went through the msconfig process again and this time when the sytem came back up system recourses went immeiately to 75-100%.

What do you think?

Thanks!

Is this a desktop or laptop PC? You should fill out your system specs.

Any chance your PC is overheating? You could try running something like SpeedFan to see if your CPU is running hot.

What happends if you boot into SafeMode? You could try booting into SafeMode and running MalwareBytes AntiMalware or doing a scan with your AV software to check for viruses and Malware.

I think it's the reboot that's fixing things, and msconfig isn't doing anything but making you reboot . When you say "using 75-100% of resources", do you mean CPU percentage used? Memory usage? Both?

It would be useful for you to open resmon, go to the CPU or Memory tab (depending on which resource is being used) and sort by either CPU (CPU tab, if it's CPU that's being consumed) or Working Set (memory tab, if it's memory that's being consumed). Do this when you first boot up and leave it open and running - that way the next time it occurs, you can switch to it and see what's happening.

Welcome to SevenForums Pete.

"slow downs" are sometimes caused by autoupdate of MS or other software occurring which is why I always opt for manual updates.

If you disconnect from the Internet and any local network, then power up your computer does the same thing happen?

What software did you just install?

What anti-virus are you running? The least-interfering and most effective anti-virus is Microsoft Security Essentials. I recommend:
1. download Microsoft Security Essentials.
2. Disable your present AV software.
3. Remove your present AV software.
4. Install Microsoft Security Essentials.
5. Run Microsoft Security Essentials Full Scan this first time. Afterwards, you can use the Quick Scan.

Download, install and run MalwareBytes. Please use the supplied link.

Please download and install Speccy then copy and paste from Speccy into your system specs (User CP at top of page, then click on Edit System Specs).

svchost.exe

I think I have a problem with svchost.exe There are a bunch of these running. How to fis this?

Thanks!

 

[neo101]

Press 'control' + 'alt' TOGETHER then the 'del' key

"Start Task manager"

Have a look thru your 'processes' + other menus

It might be an 'add-on' prog (HP/Dell/Acer made etc) that got screwed with an m/soft 'update'

There are normally 10-12 'svchost.exe' running on my PC - any more I would suspect you have a trojan/virus!

Please reply giving further computer info make/model, type of Windows OS etc

Do NOT touch svchost.exe. This is used by many, many MS and other programs and services.

First perform the steps requested. Help us help you.

+1 -svchost.exe processes are *normal*. Unless your antivirus app finds a problem with one, DO NOT TOUCH IT (and if your antivirus app is McAfee and says there is a problem with an svchost, DO NOT TOUCH IT ). Do what was requested here previously, please.

1. If you have any existing antivirus product installed other than Microsoft Security Essentials, remove it.
2. Download and install Microsoft Security Essentials.
3. Update MSE, and then run a scan of your system with MSE to make sure it does not find any threats you should be dealing with.
4. Download and install Malwarebytes.
5. Scan your system with Malwarebytes to make sure it does not find any threats you should be dealing with.

If you get to this point and your system is clean according to MSE and MWB, please reboot, and then run resmon (as previously instructed) to see if you can reproduce the issue while resmon is running. If so, you should be able to get an idea of which process or processes is/are consuming your memory, CPU, or both at the time the system slows to a crawl (if you can take a screenshot of resmon while this is occurring, even better, but I understand that may not be possible).
