Hello everyone, I am currently narrowing down the error... I assembled a new PC in autumn 2023. The following components were installed: - ASUS ROG STRIX X670E-A GAMING WIFI - AMD 7900X3D - Kingston FURY Beast (2 x 32GB, 6000 MHz, DDR5-RAM, DIMM) - SAPPHIRE 7900XTX Nitro - I have 2x NVME SSD and 1 SATA SSD and 3x HDD Runs on Win 11 Now the problem I have at the moment is that the mouse lags sporadically, about 1 sec 3x freeze and this occurs somehow every 10 to 30 minutes. Sometimes more often. Strangely enough, however, as soon as I play Starfield, for example, or other games that I play in full screen, the freeze never occurs! With games that run in windowed mode, the freeze appears from time to time. On the task manager, I can see that the CPU is not really under load every 24 logical CPUs, but only at a brief peak that somehow lasts less than 1 second. I would like to discuss this with you and find the error. What I have already done or checked, but which unfortunately did not lead to success: - fTPM deactivated under UEFI - UEFI or BIOS updated to the latest version 7 Feb 2024 - Windows 11 completely reinstalled These are the points I researched on the Internet. My guess is fTPM... But since I had deactivated it once, but no success, I think the problem lies elsewhere :( Thanks for your help :)
