Razer Blade 15 Advanced (2019) CPU/GPU overheating

Hey guys, looking for advice. I have had my 2019 Blade 15 Advanced (rtx2070 max q, Intel i7 9750h) for just 2 years. I don’t game often and mostly use the laptop for school, work and web browsing. I recently noticed my laptop has started to overheat even under no significant load (monitoring with HWMonitor after it started freezing and requiring hard shutdown). The CPU/GPU both go up to 90c+ shortly after booting with nothing running, monitoring task manager and both CPU and GPU utilization is under 10%. I took the laptop open and the battery was also swollen. so far I have: 1. Replaced swollen battery 2. Cleaned out all dust / fans / cooling and repasted CPU/GPU 3. Updated bios / firmware and clean windows install. 4. Edit* I’ve also gone through all drivers to ensure they’re up to date. 5. Edit* I also used a voltometer on the laptop power supply and it is outputting 19.5v as it says it should. 6. Edit* I’ve also ran scans with Malwarebytes and nothing to report. Issue still persists.. I’m extremely disappointed as I thought this would be a reliable laptop for how expensive it was, and it’s only really seen light use. I’m just out of warranty now.. any other ideas? The last thing I can think to try is to undervolt the CPU just to make it usable for a short time and see if that helps.. also I do have the laptop sitting on a hard surface and on a cooling pad. I’ve also gone into the BIOS to check settings and noticed the overheating / freezing occurs after being in the bios for a few minutes. So it’s happening even pre OS boot. The fans appear to be working fine and the inside of laptop is clean. I’m stumped.
