High CPU Usage Windows XP Pro (Urgent)

by masrar / February 16, 2004 4:52 AM PST

I am using an AMD Athlon 2000+ Processor and 256MB Ram along with an Onboard ASUS Motherboard.The operating system is Windows XP Professional. The problem is that my computer's system consumes up 80-95 percent of the computer's performance. Eventhough there is no program running, this problem still persists. It is as if there is a secret program running in the background which consumes all of the system's performance. But how is this possible? I found out that there could be spywares, adwares or a possible trojan virus in my computer. I cleaned up my computer from all spy and adwares. I also scaned my computer a dozen times with various up to date antivirus programs. The only thing I came up was a possible trojan virus called pornovideo.exe within my system32 folder. I deleted the file. I tried everything but there is no imrovement on this issue. The CPU usage still boosts up to 95 percent without much decrease. One additional point is that I can use all my programs without them being functioning slowly. This seems absurd. With such high CPU percentage this shouldn't have been possible. What could be the cause of this high CPU usage? What are the possible solutions without losing much? Is there anyone out there who can help me out on this urgently? I need somenones help. Thanking you in advance.

Re:High CPU Usage Windows XP Pro (Urgent) = The item is a "gimme."
by R. Proffitt Forum moderator / February 16, 2004 5:06 AM PST

You have a few issues to work, but imagine the poster that claimed the CPU was always at high CPU usage because the process titled "Sytem Idle Process" was always nearly 99 to 100% of the CPU cycles. They revealed their new to this OS status very quickly.

As to the .EXE you noted, I would do two things.

1. Get all the OS updates installed. This is non-negotiable since a new install can quickly be infected with the Blaster or any of the varients that your Antivirus will not stop. You can skip all the application updates like Windows Media Player and always second guess Microsoft if a driver is offered!

2. Perform ALL five scans with the tools noted at http://reviews.cnet.com/5208-6132-0.html?forumID=32&threadID=1313&start=0 and hunt up the new link to CWSHREDDER. If you decode to do less than the five scans, reveal this in your next post why you didn't so that discussion can start.

Best of luck in your bug hunt.

I wonder could ya help me? I am very new to this OS and have the above mentioned - "system idle process" @ between 85 to 100%. This is not problematic? Computer is much slower since uprade. 128 meg RAM enough? I'm suspecting not?

Dear Bob,

Thanks a lot for your reply. I always download the critical and recommended downloads for OS. I had already tried out all the programs you have mentioned earlier today. Nothing came up. The problem still persists. The winlogon.exe file condumes all the On a certain website I found out that there is a trojan named backdoor.trodal that uses winlogon.exe. I suspect that this could be the one. But I couldn't find it in my computer via all the scans (ad-aware, spybot, norton, AVG6, Panda, PC Cillin, Stinger, CWShredder). Is formating my C:drive an option? I actually don't want to format because I can't find my driver CDs. I could install XP Pro over this one? But would the problem still persist? I am really desperate on this. An other suggestions you could give me? Thanks again for your support.
Regards

Mansur

After the five tools, the next stop is... Hijackthis.
by R. Proffitt Forum moderator / February 16, 2004 10:21 AM PST

In the thread I noted, HIJACKTHIS is the next stop in finding what else is plaguing the machine. Be sure and not to run anything else to get a reduced LOG FILE for the HIJACKTHIS FORUM to peek at.

I actually have two anti-virus programs installed but they are not running at the same time. I did various up-to-date online anti-virus scans from the major anti-virus websites. The problem existed before as well. As I have mentioned, there are no programs running. And I mean nothing. And still the winlogon.exe file boosts up to 99 percent most of the time.

Hello Bob,

I did the Hijack This scan and saved the log file. But unfortunately I was unable to find anything different on the report. I am hopeless about this case. Any Ideas?
Thanks and Regards

While you looked at the Hijackthis log, did others?
by R. Proffitt Forum moderator / February 16, 2004 9:44 PM PST

You may be missing the best help out there.

I must ask this: Was I unclear about posting the log in the Hijackthis Forum?

The sad part of your story is that its a FACT that your machine has suffered virus/trojan/other damage. You need some help with the HIJACKTHIS log plus you'll get to run SFC /SCANNOW later to try to clean it up.

For now, just seek readings of that log.

'CPU usage
by Cursorcowboy / February 16, 2004 9:55 PM PST

1. The article [Q310419] describes issues concerning computer speed and decreased performance caused by programs loaded at startup, programs that create memory leaks, and the situation when a computer has a small or minimal amount of random access memory (RAM) or a slower central processing unit (CPU).

2. The article [Q314056] describes Svchost.exe (%SystemRoot%\System32 folder) the generic host process name for services that run from dynamic-link libraries (DLLs), can run in multiple instances at the same time, and each session can contain a grouping of services so they can run depending on how and where it is started. Please note, the built-in Task Scheduler -- a huge word that (Schedsvc.dll) component, is made up of the MSTask.exe service file and a user interface (UI) component in MSTask.dll that you can use through Windows Explorer or through Control Panel and is hosted by the file Svchost.exe in the Netsvcs group.

Note: If you feel a service stared and running is to blamed for the excessive CPU usage, use the procedure in [Q811267] to stop services one at a time simply for the purpose of determining which one could be causing the anomaly.

Have you checked your 'Services' with the Black Viper site...
by John Robie / February 17, 2004 12:12 AM PST
http://www.blackviper.com/WinXP/servicecfg.htm

"....of 89 services, 36 are set to Automatic as DEFAULT, but, we MAY only need 8 running.."

http://www.blackviper.com/WinXP/service411.htm


Just one of the Services that may cause high CPU usage:

"Indexing Service
This service always has been a major resource hog. I NEVER recommend having this service enabled. Remove the function via the "Add / Remove Programs" icon in the control panel (Windows Setup Programs). It uses about 500 K to 2 MB in an idle state, not to mention the amount of memory and CPU resources it takes to INDEX the drives. I have had people (and witnessed it on other people's computers) report to me that the Indexing Service sometimes starts up EVEN while the system is NOT idle... as in the middle of a game. You may feel, as I do, that this is unacceptable. If your computer suddenly seems "sluggish," Indexing Service is usually the cause of it.
Default XP Home: Manual
Default XP Pro: Manual
Safe Setting: Disabled"
