For some reason, trivial programs are hogging up 99 to 100 percent of my CPU usage. I'm talking about things like AIM, Internet Explorer, or even trying to run Disk Cleanup. I have no idea what's wrong, but it's really irking me! Not sure if this is the right board to post this in so.. any help you guys have would be greatly appreciated! thanks!

How big is the drive, how much free space, is the virtual memory set correctly, how much installed ram memory is there

Download, install and run Tune Up 2006 Trial

Click start then run, type prefetch then press enter, click edit then select all, right click any file then click delete, confirm delete.

Run Tune Up disc clean up

Run Tune Up registry clean up

Click optimize and improve to run Reg Defrag, the screen will lose colour during the process which can take a few minutes and then needs a reboot

Those will have cleared the drive of obsolete software errors

These are suggestions for making the most of the free trial

After the reboot, click optimize then system optimizer to optimize the computer, select computer with an internet connection from the drop down menu, this also requires a reboot

After the reboot, click optimize then system optimizer to accelerate downloads, select the speed just above your actual connection speed, this requires a reboot.

After the reboot, click optimize then system optimizer to run system advisor

107GB hard drive, 64% free space, 1GB RAM, I set my Virtual Memory to 'System managed size,' but with no improvements.

I ran all of the scans you listed. It cleaned a bunch of crap from my computer which is good, but the CPU issue still exists. I really don't know what the problem is, and the 2 other GeeksToGo staffers I have talked to seem to be stumped.

With what you say, there's no reason why it should be lagging like this. Do you know if the CPU is overheating?
Can you verify the motherboard temperature sensors for us?

Don't know that it's overheating. Don't know how to check the sensors.. I wouldn't know what is 'too hot' anyway. I thought about just reinstalling Windows XP but I don't want to lose all my files I've acquired over the years. :tazz:

It really doesn't make any sense - one day I attempted to remove the Winfixer virus. Then the next morning, when I turn on my computer, everything has gone to [bleep].

Motherboard temp: 53 degrees C (127 degrees F)

CPU temp: 67 degrees C (153 degrees F)


These were measured with my CPU pegged at 100%

Wow, those temps are very high. I'd guess your CPU is "throttling" due to the high temps, and that's why it appears to be running at 100%. There seems to be a heatsink issue. Have you confirmed the fan is working? Did you build this system?

I think you guys might have it backwards...the temp is up because the CPU is running 100%, not the CPU is running 100% because the temp is up.

I'm going to take a flyer here:

O20 - AppInit_DLLs: C:\WINDOWS\system32\wmfhotfix.dll

There was a wmf metafile fix floating around the Internet recently, that creates this setting above.

Somewhere around Jan 10, MS released it's own patch....have you visited MS Windows update since then, or do you have automated updates installed?

If so, you should have removed the hotfix that was floating around the internet (called HExblog's wmf patch, or something)

Not removing the patch, and installing the MS fix on top of it, could have ugly consequences.

Check add remove in control panel and see if both


kb912919
Windows WMF Metafile Vulnerability HotFix"

are installed (check the SHOW UPDATES BOX at the top in SP2)

If so, uninstall them both, then revisit MS Update and reinstall

I had installed both the hotfix and windows update (it's set to automatically update). I removed the hotfix. Unfortunately there is a problem with my IE to where I cannot access anything past the homepage (this problem happened simultaneously with the outrageous CPU usage), so I cannot get to Windows Update. Tried to access it via FireFox (which works), but the site says I need to use IE since it's a Microsoft site and all.

did you uninstall both? After uninstalling both, reboot.

Does the problem recur

(will worry about update in a moment)
