Your PC ran into a problem…. Error no Wi-Fi showing as well heating and switch off
Often, rebooting will fix the problem. If not start with the HDD. Remove it and set it up as an external USB drive on another computer. Run CHKDSK on all the partitions. That may fix it. If not and it shows errors, you may need to offload all your stuff, reformat the drive and reinstall windows. There are other possibilities that might be fixed without a reinstall, but troubleshooting them and the fixes are complicated.
@nmk Not sure what you mean by “It heated up in very short time…….”. If the laptop is overheating, temperature wise then there is a cooling problem, either due to a fan problem, thermal past needs refreshing on the CPU or a motherboard problem and usually the laptop is shutdown to protect the CPU not continuing on and starting and then encountering problems, unless it is a borderline temperature problem I suppose. Try starting the laptop in safe mode with networking and check what happens
