AMD 1100 PhenomII
Asus Sabertooth 990 MB
Intel 120gb ssd

Task manager says use is system idle, and seems to be kernal (red). I've disabled system indexing. and search, no change. Can't find any hardware issues in hardware manager. I'm going to see if I can update the MS anti malware protection mow.

Sure does not look like malware.

Please download ComboFix from any of the links below, and save it to your desktop. For information regarding this download, please visit this web page: http://www.bleepingcomputer.com/combofix/how-to-use-combofix

Link 2


* IMPORTANT !!! Save ComboFix.exe to your Desktop

IMPORTANT....

1. Close any open browsers.

2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

3. Do not install any other programs until this if fixed.

Double click on ComboFix.exe & follow the prompts.

The log is clean.

What do you suggest do you wish to continue searching for Malware or check with an other forum.

If you go to the Main page you will find a number of forums. Select the one which is appropriate to your probem.

Well, it certainly is interesting! I think I shall try another avenue, I'll inquire of AMD if this could be be the CPU itself. I will refer to this forum for evidence we have looked for malicious software. Thanks for your excellent support! I will keep you posted.

nasdaq, here is another wrinkle, while combofix was running, the usage on core #6 went down to 75%. Does this suggest anything? I tend to see this as an indication of a problem other than hardware.

I think I might try scrubbing the ssd, pulling the battery on the mb, flashing the bios with new firmware, and loading ubuntu to see if the problem persists. What do you think of this plan?

ComboFix is CPU intensive. Why would this go down? I do not know.

That is your call.

Would it not be easier to find out from the other forum what could cause this.
I know I would before flashing the bios. Mind you just flashing the BIOS may do the trick.

This is not my forte.

Hi nasdaq, I found the problem. It was a bad comm port card I had installed when I built the thing, but not used. Seems it went south. I was looking around and noticed that device manager reported only 1 comm port, and there should have been 5. Also resource manager reported the usage was... well just look at my post in the internal hardware forum. Thanks for your help, and advice to visit another forum. I was about to call a witch doctor!
