Hey guys, my work machine 'sometimes' gets very slow and erratic, it is not virus related and is not browser issue. When I look at the task manager's Processes, I am not seeing anything unusual in the CPU column and whenever this happens, I restart the pc and all is fine, how can I find what might be causing this intermittent problem please?

Take a look at this tutorial using Process Explorer. When the computer lags Process Explorer may give you a clue on which process is causing the problem. Check Event Viewer for any errors.

I would also check your temps during the lag.

Have you or anyone used Process explorer? I can't figure out what to look for in it when my pc is hanging? Speedfan temps looks normal when pc is hanging and the pc is cold to touch so overheating issues.

I don't have a lot of experience with Process Explorer. Did you find anything in Event Viewer? You may want to start a new thread in the Crash/Hang Forum where they can look at your logs.

It didn't hang yet because I haven't done as much as I normally do, when next it hangs I will post in the crash/hang forum, also I will look around for a forum which discusses process explorer, thanks

You may want to take a look at Process Monitor. That shows your processes in real time but I don't have any experience with it. I think your best bet is the Crash Forum. Good Luck.

It's only 2gb ram and core2duo. I usually have more than 25 tabs open and keep switching between them plus having a few word and excel files open. I am wondering if maybe this old unit just can't handle the heavier workload? Whenever it hangs and I restart it works like new again.

If those 25 tabs are for Chrome then I would have to agree. That is even high for Firefox. Start Task Manager. In the View tab under columns select Peak Working Set Memory. That is the highest memory logged for that particular process. Try to keep your tabs to a minimum.

Could be, could be.  What does Task Manager say when you have so many tabs and programs open at once?  BTW, here's an article on using Process Explorer.

I decided it's time to upgrade so i ordered a brand new pc but the curiosity in me would like to find the culprit and I have one more week to do it.

Sorry not understanding the question? Thanks for the article, I have also joined the PM forum for help.

Agouti is probably referring to How many "Processes" "CPU Usage" and Physical Memory" are being used.  You will see this at the bottom of "Task Manager" as you probably know.

 

IMO, W7 will give you troubles if you run it so hard on a low powered system as you have.  At the least you should upgrade to some good RAM if possible, and maybe some other speed or Resource Reducing cleanups.

 

Now that you bought another pc - and if you are adventurous - you could try out Linux on the old pc, maybe a Dual Boot with Windows and Linux.  Linux will run much faster with such a pc, I know because I have two  with Dual Core CPU's, one with 3GB of RAM and the other with 4GB of RAM.

 

I think you will find that you are just running to many Processes for that pc.  It's always good practice to post the specs of the pc also, because some might have experience with the same very same one.  Things like CPU Cache, brand of CPU, HDD Type etc. these all tell a helping hand what the pc is capable of.  I would never have that many Tabs open on my Dual Core while running many other apps also, it just won't handle it consistently.

 

Consider turning off "Disabling" any Extensions that you don't need in your preferred browser, google it!  They come with some Enabled that a person might not even use, so take a look.

Right now with 29 tabs open and a few word docs TM is showing  Processes 60, CPU Usage going continuously between 1 and 64% and Physical Memory 61%. I use mainly FF for browser.

Well your CPU don't seem too taxed, I would say you are having issues because of RAM, but you will need to do some testing to find out for sure.  I'm no Tech, but RAM is usually Shared, so if it is showing 60% it might be getting toward it's limits and when you aren't looking it hits the limit.  Here is another article that covers some of what has already been said here.  It is HTG and covers the basics.  I wonder if you can obtain this pc once your Employer gets you the new one?  The Event Viewer or the Reliability Monitor should show you what you need to know.
