I recently had my laptop's keyboard replaced after the WASD keys failed from normal wear. Since getting it back, the entire system has become unstable. Programs gradually begin stuttering, freezing, and lagging, while any playing audio becomes slowed down and extremely distorted. The issue sometimes improves temporarily, but it can also worsen until the laptop suddenly powers off without displaying an error. Even outside the worst episodes, performance is noticeably worse than before the repair.
Device Manager occasionally shows a warning icon on the laptop's Nvidia RTX 4050, with the message: "Windows has stopped this device because it has reported problems (Code 43)." I have also briefly seen a shutdown entry named something like "RxDiag.32.2024," although I cannot locate that program afterward.
So far I have updated Windows 11, cleaned the vents with compressed air, tried updating both graphics drivers through Device Manager, run a Windows Security scan, checked Task Manager during the freezes, and looked for unfamiliar installed programs. Nothing has helped, and Task Manager freezes along with everything else. The problems began immediately after the keyboard replacement, so I suspect something may have been damaged or left improperly connected during the repair. Unfortunately, the repair shop's building was badly damaged by a tornado and is currently unavailable.
Would a clean Windows installation be useful for ruling out software, or does this sound more like a hardware or repair-related problem? I have backups and could reset the laptop if necessary, but I do not want to make the situation worse.

The timing strongly suggests the repair shop may have caused or failed to reconnect something properly. Code 43 can be caused by a driver issue, but with severe system-wide stuttering, distorted audio, crashes, and a GPU warning appearing immediately after the repair, a hardware or connection problem is very plausible. A different qualified repair technician should inspect the laptop before you spend too much time troubleshooting Windows.
A clean Windows installation can help rule out corrupted drivers or software, but it should be treated as a diagnostic step rather than a likely fix. Back up anything important first, then install Windows from a USB installer and remove the existing system partitions during setup. Afterward, install the laptop manufacturer’s chipset, graphics, and device drivers. If the RTX still reports Code 43 or the stuttering continues on a clean installation, that would point much more strongly to hardware damage or an internal connection problem.
That is what I am worried about. Unfortunately, the original shop cannot currently be reached because its building was badly damaged and has no power.
