CPU usage high after upgrade.

Problem: My CPU usage is waaayyyyyy higher than it use to be.

Here's the history, I got a new video card and heatsink/fan, and upgraded my RAM with the exact same kind I've already had.
I had to take off my mobo to put on the brackets for the new heatsink/fan for my CPU. I was careful cleaning off the old thermal paste, etc etc. I changed my 4870x2 ATI card for a new Nvidia 680. and my ram from 6gb to 12.

I forgot to uninstall the old drivers when I put in the new card, and when I turned it back on, my cpu was stuggling so hard at 100% when I first started up, but my temps aren't even going above 50. I've checked to make sure it was reading all my stuff right, I uninstalled the ATI drivers and used drive fusion to remove the left overs, and installed the new Nvidia drivers.

But still my CPU usage is running so much higher. All my start up programs use to be nothing to my CPU. Now I have to turn pretty much everything and I will still idle around 50%. I will try to play WoW and I might get like 5fps, but my CPU doesn't even max out then, everything seems to be using a lot more CPU or something. I really don't know. I've tried so many things.
I've tried taking the RAM back out, I've double checked to make sure I put my heatsink/fan on correctly, I've tried unplugging my usbs, and my new monitor's HDMI, but nothing, I've scanned to make sure it wasn't a virus, I've checked to make sure there are no extra processes for the most part. I've double checked to make sure the ATI drivers are gone, I've reinstalled my video drivers a few times, I've made sure my bios and chipset drivers are up to date, I've even tried clearing my CMOS and still nothing.

The only progress I've made in solving this is that my DPC latency is very high.
I really really need to fix this. Please help me. :\

  1. One think that will help quite a bit, what is your CPU!?
  2. Haha sorry. I forgot to include my specs.

    I also used sfc /scannow
    It said Windows Resource Protection found corrupt files but was unable to fix some of them.

    Would the CBS.log help?
  3. Yes.
  4. You should be able to see exactly what is using your CPU from the CPU column in the Processes Tab in Task Manager
  5. Hi :)

    Run a hard drive test in DOS...HIRENS CD etc, it sounds like a failing hard drive...

    All the best Brett :)

    You can see in my picture what's eating my CPU. But I don't think that's a problem. I've pretty much killed everything accept windows tasks and some resource monitors. But still those things should have been cake for this processor before.

    Nope. Nothing seems to be bad there, I just replaced my hard drive maybe a little less than a year ago atleast. Why would you think that would be what's wrong if I may ask. But it still never hurts to check;)

    Hi :)

    I didn't say run scannow... it checks windows files NOT hard drive sectors...

    All the best Brett :)
  8. Hi :)

    Oh and we have seen 1 day old hard drives which failed in my shops...run Hirens FULL test...

    All the best Brett :)
  9. Haha, I did a chkdsk further down.
    But I'll try Hirens.

    Hi :)

    Hehe, chkdsk is chocolate tea pot time :)

    Use Hirens in DOS...

    Haha ok. I thought so.
    I'm downloading the latest version right now. I'll let you know how it goes. :)
  12. Ok so the test came back fine, no errors or anything.
    I'm still questioning how that would cause my CPU's load to be so high, maybe it would affect my DPC latency but I'm no expert. Anything else? :\ This issue is very annoying.

    Also the sound seems to stutter sometimes when I play videos on youtube.
    Another thing I've noticed is that if I don't type or move my mouse, my usage will be around <10% but my DPC latency is still high. But once I do anything it will shoot back up to 50-70%.
    Could it be my CPU dying?


    Edit:

    So after some searching. I found this.
