How to detect a miner/virus (perhaps in the BIOS)?

Question

Windows

I’ll immediately notice that I’m working on a laptop from Asus ROG GL753VD with i5 7300HQ, 12GB RAM, GTX 1050 and official Windows 10 (maybe someone will need it)

For more than a week, the laptop has been behaving very strangely. What it is expressed in: without any load on the system, the cooling plows like I'm working simultaneously in Photoshop and After Effects with Chrome in which 100 tabs are open. I tried to understand what the problem was and first of all opened the task manager. The first moment it is clear that the load on the processor is going to capacity, but already at this moment the load drops sharply to 7-10%. I started looking for this malware, which loads the system in such a way, but I did not find it. The thought came to my mind that the miner picked up the virus and now he is sitting somewhere in the depths and eating my resources. I tried to find it - I did not find it and decided to reset the system through the "Recovery" item in the Windows settings. But nothing happened, a window with a choice of reset option opens and immediately closes. The program from Microsoft to create a bootable USB flash drive did not start ... As a result, I made a bootable USB flash drive from friends and reset the system like this. Winda is completely clean, but the coolers are again plowed at maximum speeds, and the processor is loaded at 100. I rolled the MX Linux distribution onto another flash drive and did a complete cleaning of the SSD disk on which the system and HDD with all the data stood. You never know, maybe this creature is sitting somewhere on another disk. Cleaned, rolled Windows and all the same. I started looking for other information and found nothing particularly. I remembered that there is such a thing as a virus in the BIOS. Is there such a possibility that some kind of nastiness has penetrated the BIOS and is now sitting there devouring my resources? If yes, how to neutralize it? I would be very grateful to all those who can help in any way!

Answer 1

disassemble the laptop, clean the dust, change the thermal paste to the CPU and GPU,
set the Windows standards, like ltsc, disable updates, disable sysmain
everything
if you think that the virus is supposedly in the BIOS - update the bios, from the flash drive, from the off site
now everything is for sure
