Startup Error 90D, Laptop thinks its hotter than it is and GPU undetected

[DonZa95]

Hello,

I'm pretty upset. When turning on my laptop  today I was greeted with the message below along with my fans being maxed out which they never even do when gaming.

"The system bios has detected your notebook PC was placed in hibernation to avoid overheating .

The system is now operating normally and your data should remain intact.

Overheating may occur if the cooling vents are blocked or the operating temperature exceed the specification. The notebook PC should return to normal operation once the situation is resolved.

System Temperature (90D)"  

I find this strange as my laptop was operating normally the last time I turned it off and I always monitor my temperatues in games using afterburner, never seeing higher than 70 degrees celius and its rarely that high, on average its 50-60 degree celcius when gaming. Same with the CPU. I also noticed that my GPU was also no longer being detected and instead an 'unknow device' and Nvidia drivers fail to install too.

I decided to open the laptop (doesn't void warranty on this model) and blow some compressed air through the fans but that has made zero difference and they weren't particually dirty any way.

Upon further inspection I've noticed that the laptop thinks its overall temperature is 75 degree celius (in HWMonitor by  CPUID) the entire time and will not change, even after being shutfown for an hour, however the CPU and HDD are 30 degrees celcius and 23 degrees celcius and do change. For example I can leave it off for 'x' amount of time but the second I turn it on it thinks it 75 degrees C.

Things I have tried are,

- Cleaning fans (wasn't that dirty)

- Resetting laptop to factory settings

- Updating Bios

- Disconnecting battery and holding power button for 30 plus seconds

and nothing changes, still I have no GPU detected, still I have the Error 90D on startup and still my fans are maxed out.

I'm really stuck as to what it wrong. I hadn't changed anything on my laptop in a long time. Its mainly for games and its only just over a year old. I should also add that my laptop never moves from my desk.

Any help would be appreciated,

Thank you.

From bios setup turn on fans always enabled and update latest gpu driver from Official site amd or Nvidia you have not from your manufacturer and try to update latest integrated graphics driver same way,  also install latest visual c++ from Microsoft 2019 includes all previous redistribution.
