Hi!

Not sure where to post this problem since identifying its cause should be a part of the solution I’m looking for. Long story short, something on my computer is keeping CPU usage at over 50% with 40+ processes going on at all times. Here’s the long story BTW:
http://www.malwareremoval.com/forum/viewto...cc31d794b9bf9a3

As you can see, malware is probably not to blame. Could it be related to graphics card drivers or mother board BIOS version? Or something else? Any help will be appreciated!

My specs:
OS: Windows XP Home SP3
CPU: Athlon 64 3200+ (winchester)
Motherboard: Gigabyte nForce 3 Ultra (K8NSNXP-939), BIOS version F6
Graphics card: Asus AH4650 (AGP), driver version 9.6
Memory: 2*1 GB of DDR400 (PC3200)
Hard drive: 160 GB (105 GB free)

do you have alot of programs in your processes? get rid of some programs you dont need and it might lower the CPU usage?

The amount of processes is not overly excessive. However your CPU should not be running that high. What are you using to monitor the % usage of the CPU?

Sysinternals Process Explorer. Today I also checked out the Task Manager, and it's telling me the same thing. System Idle Process is currently responsible for 80-100% of CPU usage AFAIK. CPU usage itself is always above 50%.

RS8,

Have you clean your temporary files?

If you have CCleaner or REVO Uninstaller run the file cleaner on either of them, I think CCleaner might be slightly better.

System Idle Process...represents INactivity of the CPU. Higher numbers are preferred when the system is doing nothing.

RS8,

I took 2*1 to mean 2 times 1 for a total of 2gig of ram, which should be plenty. Do you get any messages about virtual memory low?

Thanks for the info! I "sort of" knew what it meant, but it's nice to get clarification. Poor choice of words on my part.

But I'm afraid that doesn't explain why CPU usage remains at 50% or more even when the system's doing nothing.

2GB of RAM in total, yeah. No messages about low virtual memory or about anything else for that matter, but the computer does feel slow.

Thanks a lot for the CCleaner recommendation, I had only removed the temporary Internet files up to that point. I'll see what CCleaner can do later today, but right now I gotta study. In the meantime, any new idea will be worthy of consideration.

You need to identify which process (besides the system idle process) is using high CPU. Something must be responsible for your cpu usage being above 50%.

Maybe you can post a screenshot of your Task Manager.

Maybe DrWatson is running, if that's the case, look up "how to remove drwatson" on a google search. It's pretty easy instructions.

I found this:


1. Click Start, click Run, type regedit.exe in the Open box, and then click OK.
2. Locate and click the following registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AeDebug
NOTE: Steps three and four are optional, but they necessary if you want to restore the default use of Dr. Watson.
3. Click the AeDebug key, and then click Export Registry File on the Registry menu.
4. Enter a name and location for the saved registry file, and then click Save.
5. Delete the AeDebug key.

Hope that helps.

Post a screen shot of your Task Manager and there will be no guessing.

Right click the Taskbar, choose Task Manager.

Click View, Select Columns, check the box that says: Virtual Memory Size. Expand the
width of the Task Manager box so you can see all the columns and processes.

Double click a column heading in TM to sort by the column. For example,
sort Task Manager by the CPU column.

Take a screenshot of what you see and upload the screenshot to one of several
free picture hosting WWW sites.

When you are done, we will be able to see what you are seeing.

To create and post a screenshot:

Press the Print Scrn button to copy your entire screen to the Windows clipboard.

Press Alt Print Scrn to copy just the active window to the Windows clipboard.

Open MS Paint:

Start, Program Accessories, Paint

When Paint opens, press CTRL-V to paste the clipboard, save the new Paint file
to your desktop or someplace you can remember. JPG files take up less hard
disk space than BMP files and just as readable.

Make as many screenshots as you need. Practice makes perfect. Be careful your
screenshot does not contain any personal information. Practice viewing your images
before you upload them to be sure they are okay.

Some sites (like bleepingcomputer) will let you attach a file directly to your post.
If the site has some kind of attachment/upload function it is usually easiest just to
use it.

If there is no such function then use a free third party image hosting WWW site.

Create a free account on some free picture hosting web site. You can always remove
your account later if you want. Here are some free image hosting sites:

http://www.imageshack.us/
http://photobucket.com/

Using your free account, upload your screenshot(s) (the JPG or BMP files) to the
site and it will return to you a URL web address (a link) for your new image(s)
that you can paste in a message post, email, etc.

When you are done, what you post for others to use should look something like this:

http://img163.imageshack.us/img163/6428/taskmanagerr.jpg

Post that URL web address back here in your response and we can click on the
address and see your screenshot. Post as many as you need - the sites are free.

Below is a screenshot I attached directly to this thread without using a third party site:

You can use performance monitor to see what is eating up the CPU cycles. Go to control panel - administrative tools - performance. Click the - to delete all of the active default instances. Click the + and in the pop up window select process-then in select counters choose %processor time- and make sure the all instances is checked. It will show you graphically what is using the most CPU time as well as a list below the graph.

NM-koko = Virtual Memory Size
Järjestelmän vap... = System Idle Process

I'll try CCleaner now.

Ran the file cleaner and got rid of about 0.5 GB worth of files. No improvement according to Task Manager.

I also removed DrWatson as jwmghf suggested (I have the key saved on my desktop though), but the problem persists.
