System CPU usage spike

Recommended Posts

Hi, i have been experiencing a 25% spike in system. every 2-5 seconds. I am on windows 7 64bit. I have been trying to isolate the problem but have not been able to find any solutions. Using Process explorer by Sysinternals its telling me the spike is coming from specifically : ntoskml.exe!WheaAttemptPhysicalPageOffline+0x350 Im seeking advice how to further isolate what the cause of this random spike is. Cheers guys Just let me know what information you need from me and i can get that to you ASAP.

Just curious - can you get a Task Manager "Show Processes All Users" and "sort" by CPU (highest first) and maybe see Services.exe "jumping"?

Ok submix8c I'm past that point mate but thanks for your input.

Now I'm looking at Process Explorer and noticing the spiking happening. Now I can't create a dump or a mini dump(it simply wont let me). It says error opening process access is denied.

In saying that, if you re-read what I posted in OP I suggested the spike from System(taken from the system properties window by double clicking on it in Process Explorer and checking the threads tab) was coming from : ntoskml.exe!WheaAttemptPhysicalPageOffline+0x350 after this thread spikes the system.exe usage up to 25%(As in in the system properties\thread tab its the thread that spikes system.exe to 25% usage ish and happens every 3-5 seconds) dxgmms1.sys!VidMnInterface+0x26500 spikes its CSwitch Delta to 500-800.(I dont understand what that means but it may help with the diagnosis.)

When this happens it also Stutters and freezes streaming video my pc for a short amount of time.(We are talking 50-200 milliseconds here.) But from my understanding its not coming from Hardware Interrupts.(Followed the guide on the website here to see if it was hardware interrupts.)

Any Help on this matter would be appreciated. I am a fairly experienced computer user and digging this far into this problem is kind of exciting for me and i would love if someone else with more knowledge would help me further diagnose where this problem is coming from. :) Cheers guys and hope to hear from you soon.

I had an idea you'd see that .sys file. If you haven't determined already, that is a DirectX (dxgmms1.sys) file, which means you now have a direction to look at for your issues: The graphics card. There was a video card testing program I once used (and posted about here) but I can't find it now. :blushing:

So until I can remember that one, let's get back to your question. You say you have this problem, but have revealed little about what you are doing at the time. Then you do mention watching a video online. So here are some ideas and questions.

- Update your video drivers (use manufacturer not Windows Update)

- What browser are you using?

- Does it only do this when the video card is being used? (videos, flash, games, etc)

First, you did NOT say "SYSTEM.EXE", rather you said "system". You're not being very clear.

The REASON I asked about that SPECIFIC program is because a NASTY virus/trojan is going around that in just the last tweo weeks have had to "clean" from several PC's, apparently from either "drive-bys" OR Keygens"", OR a "fake AV Pop-up" that is stupidly clicked on. Google "SERVICES.EXE" and "TROJAN" to see what I mean - there's also ROOTKIT/KEYLOGGER - McAfee has a rather detailed write-up on it in a PDF file. It's a bugger to get rid of. AND it "eats" the CPU usage sometimes WAY up there to where you can't even click on anything.

In one case, I had to lower the SYSTEM.EXE Priority and do a "Repair Reinstall" (Win7 Premium x64), and manually delete (via a LiveXP/LiveLinux) the offender (VERY hidden in the User's folder). AFAICR, I had to (in safe mode) make another Admin UserID to get back to Normal Boot. BTW, the UAC was turned OFF (a side effect of the nasty?). Next, I had to go into the Registry and isolate the entries and either correct some OR delete some. WOOHOO! 2 days work for $30! Not happy!

In the other case, I didn't want to go through the same thing - Daughter purchased used laptop that DID have OEM Vista but some moron (previous owner) had installed a BOGUS Win7x86Ultimate (Grub BootLoader stunt). Managed to delete a couple of offenders BUT it deactivated. ENOUGH, says I, and used EasyBCD to add the Restore Boot Image in the (luckily still there) Recovery Partition and did a Factory Restore (that was 3 hrs by itself). THREE days and $0! WOOHOO!

Now, back to your info that you just gave - are you the same guy posting on some other forums? I ask because I see only a couple exactly related to your post with the exact same PE results (now that you've given that last "tidbit"). IF you do a search on what I said, you WILL find what I'm talking about. Have you been bitten?
