Dual Monitor Issue

Ok so here is what this is about.

I stream and it's easier to have a dual monitor to do so. So I've got a dual monitor.
However I can no longer do anything due to crazy cpu usage. ALL the time.

I go to 100% when I open a game which I never have done before.

I was wondering if anyone had an idea why? (Its the game I am running that ends up using 100%) but it never did before? So I'm confused.

Im running
i5 2500k @ 3.3ghz
Gtx 670
8GB Corsair 1600Mhz RAM
ASUS P8Z77 Motherboard
Any help would be appreciated.

  1. Do some virus and malware scans to scan for infections that can slow down your computer, use disk clean up to remove temporary and unnecessary files, defrag your hard drive and download this to check for any harmful processes/services that might be running - http://technet.microsoft.com/en-gb/sysinternals/bb896653.aspx
  2. That shouldn't be happening - your CPU has nothing to do with that, I would do with jay said, look for malware, and if that doesn't help, experiment and figure out what's going on.
  3. I have read that it should not affect my CPU however it just seemed largely coincidental that I plug in a new monitor and my cpu goes haywire.
    I have the process monitor open and SVChost.exe and Trustedinstaller.exe are using 374000 KB each
    That isn't normal right?
  4. End 'Trustedinstaller.exe', that MIGHT be the problem.
  5. Its gone

    I have just tried to run my pc with the HDMI alone and then the VGA alone
    both still give me the same results

    I am unable to do a system restore as the point is to where I installed an update. AFTER dual monitors. All previous restores have been wiped...

    Trustedinstaller.exe is gone and still I am receiving the same issue.
    Somethings on my computer. It has to be but Im not sure what.
  6. Did you download anything when you connected the second monitor?
  7. Nope I haven't installed anything for ages as I play on a select few games.

    The only thing I downloaded was After I realised the 100% cpu usage and that was the drivers for the monitor. Although its a PnP monitor that should be automatically recognized
  8. Does the problem go if you disconnect the second monitor now?

    If it doesn't go then the problem isn't the monitor.
  9. No the problem has not left.

    I have tried both monitors singular. (HDMI and VGA) and the problem persists.
    Although from in a game I don't seem to notice any decrease in performance.

    I'm having a feeling the effect is purely a placebo from actually being able to see the cpu monitor in a game, as my virus scan has come back clean. No files have been installed so I can't foresee how I would of have gotten anything
  10. Well the problem isn't the monitors so we can cross them out.

    Have you tried using older GPU drivers?
  11. Everything seems to be running smoothly without changing anything

    Im not entirely sure what the issue was
    thank you for the help though :)
