    Operating System
    ==================
    Windows 10

    Computer Specs (PSU, GPU, CPU, RAM, Motherboard)
    ==================
    PSU - 1000w

    GPU - MSI 980TI not overclocked.

    CPU - i7 4771 built in turbo but not overclocked

    RAM - 16gig DDR3

    Motherboard - MSI MS-7818

    DXDIAG
    ==================

    Description of problem

    ==================
    FPS drops from 60-25ish as soon as games finish loading(tested with GTA5 and BlackDesertOnline so far), Nvidia Inspector shows P-state changing from 0 to 2 or 5 and MSI Afterburner shows GPU clock ranging from ~1300 to ~600.

    Once the game has finished loading it stays mostly on P2 with ~600mhz but will occasionally jump to P5 with ~1200mhz.
    There are also power-dips shown in MSI Afterburner (screenshots below) that don't seem to happen as often or drastic on our other PC. Not exactly sure how long this has been going on, definitely a few days at least.

    Recurring issue
    ==================
    Yes


    Cause/Steps to recreate the issue
    ==================
    Launch a game.

    What I've tried so far to resolve the issue
    ==================
    * Confirmed windows power settings were correctly set to Gaming/High Performance including:
    * PCI Express - Link State Power Management - Setting: Off

    * Confirmed Nvidia Control Panel 3D settings were correct including:
    * Manage 3D settings - Power Management Mode - Setting: Prefer Maximum Performance

    * Use DDU to uninstall/re-install nvidia drivers.

    * Use DDU to uninstall/install older 37xx nvidia drivers.

    * Switched GPU to different PCI-E slot.

    * Exchanged PSU with a known working one(we have 2 almost identical PCs).

    * Exchanged this GPU to our other computer and had no problems with it. It ran constant ~1300mhz on p-state 0 while gaming resulting in constant 60fps. Switch it back to the problem PC, problem starts again.

    * Added -forcepstate:0,0 command to Nvidia Inspector shortcut which was a fix I read somewhere to lock the performance state to 0, it didn't work.

    * Reformatted windows 10 with fresh installation.

    * Reset and updated BIOS.

    * GPU and CPU temps all under 70C while gaming

    Screen Shots
    ==================
    All screenshots taken while running BDO


    p2 state - 28fps - http://imgur.com/Tq2owXg


    p5 state(rarely switches to this and doesn't hold for long) - 42fps - http://imgur.com/VRYuNs9



    So it seems the Nvidia performance state is not assigning correctly. It is assigning P2 when it should assign P0. I'm almost positive it's not the hardware on the video card or PSU which seem the most likely. Also have tried a different PCI-E slot but other than that not sure if motherboard is the culprit or not. Does anyone have a good suggestion to test the MB?

    MSI Afterburner shows temps under 80C and core temp shows CPU temps under 65C so I don't believe heating is an issue. It seems to be software related but I have completely reformatted and reset/updated BIOS. Also tried to run a game before letting windows 10 update to see if a recent windows update was a problem but still have the same issue on a fresh, older windows 10. At a loss here =/

    I am considering trying Nvidia PowerMizer even though it's for notebooks or overclocking the P2 state in Nvidia Inspector so it is more align with the p5/p0 states. Both suggestions I found here http://forums.guru3d.com/showthread.php?t=397347

    If you have completely wiped and reinstalled Windows and the issues still persist, then it is definitely a hardware issue.

    What is the make and model of your power supply, please?

    The PSU is a Rosewill - Bronze Series - 1000-watt 80 Plus RBR1000-MS. As much I expected it to be the GPU or PSU, I have exchanged both from my wife's identical PC and the problem is still happening. Her PC with the now exchanged parts, is working fine.

    I would say try a fresh windows install and then install drivers from the MSI website.

    I have already reformatted and installed fresh windows 10. I tried troubleshooting the problem before letting windows update, with older Nvidia drivers, with current Nvidia drivers and with current updated windows.

    Is it possible the problem is BIOS or motherboard related?

    Well, it could be a bad card, in all honesty it DOES happen on occasion. Have you thought about contacting MSI and attempting any TS'ing from them or simply submitting an RMA?
