Hello everyone. I recently encountered a problem I couldn't find a solution for. I have a Lenovo Legion 5 with an RTX 4060 and a Ryzen 7 7735H. I bought it in 2024 and it worked great until I decided to add a new Samsung 990 Pro SSD. After adding the new SSD, I also reinstalled Windows and installed the latest drivers for everything. As a result, my laptop now works fine after booting, but there's a catch. Whenever I play CS2 (or any other game that uses the dGPU), then exit the game and switch back to the iGPU, I start experiencing micro-freezes every 10-15 seconds. Basically, as you can see, the problem occurs when switching from the dGPU to the iGPU, after which the freezes occur. The problem is likely somewhere in the processor. Only a reboot of the laptop completely solves the problem.
I tried disabling MPO, uninstalling new drivers via DDU and reinstalling old ones, messing with the power supply, and more, but I couldn't find a complete solution. One working option was to permanently install the dGPU, but then I started seeing a strange blinking bar on my desktop when I wasn't doing anything. I couldn't find anyone on the forums who knew a solution to this problem. Maybe someone here can help.
