Hey All, I have an old ASRock Z87M Extreme4 that I have just installed into a new case after having it sit in its original box for a few months while I sorted out some other parts. I am getting some stutters when moving the mouse in Windows and LatencyMon was indicating high DPC. Thought it was my new NVidia 2060, but I physically removed it from the system and reinstalled Windows using onboard VGA, with no change to performance. During Windows boot from USB I noticed that the mouse was still stuttering a bit, so I'm guessing this is a low-level issue with the mobo or BIOS directly. Mobo, CPU, GPU temps are low and I neither CPU, SSD or GPU are fully utilised. Updated the BIOS to the latest version - no change. Can anyone suggest anything else I could check? Are there any BIOS settings that could possibly cause this? Thanks for any help. PS. Mobo & CPU temperatures in 30s (celsius), so unlikely heat related. |

What devices do you have plugged in? Sometimes this kind of thing can be caused by a USB device causing a conflict or just being faulty. -------------

The only peripherals are my wireless mouse and a wired keyboard. I have tried a different wireleess mouse, with the same results. Unfortunately I don't have wired mouse to try. I've tried unplugging the keyboard and testing - no change. Inside the case the PC is quite simple: Mobo: ASRock Z87M Extreme4 CPU: Intel Core i5 4670K. No overclocking. RAM: 8GB of DDR3. No overclocking. PSU: EVGA 650W GPU: GeForce RTX 2060 (I did try physically removing this card and re-installing Windows again using on-board VGA, with no change) No overclocking. All temps are on the cool side - case is roomy and ventilated. |

Is it only the mouse that is stuttering? It could be the wireless receiver causing DPC issues, its unlikely but worth a shot if you can find/borrow a cheap wired mouse. If you have not already, try a different USB port for the mouse, maybe one of the USB 2.0 ones. You can also try removing the GPU and booting into the OS with the integrated graphics and test your DPC without it installed. If it's still high then it is either not the GPU or the (nvidia) drivers are not cooperating. -------------
