it's a common problem happens with everyone once in a while.
What happened with your PC is your RAM got dusty and its functions are not working properly.
Follow these steps.
1. Turn off the power supply.
2. disconnect every single cable from your CPU.
3. open up the CPU case.
4. look for where is RAM placed.
Do everything Slowly and patiently. Relax and do as i say.
5. take out the RAM. (there will be side locks on ram which you will unlock and then take out the RAM)
6. Clean the gold looking blocks with Tissue slowly.
7. put it back. Lock it properly. (be careful when you put it back, bc sometimes you didn't putted it back correctly, so check it thrice).
8. Put all the cables back and there you go. Turn on your PC and see the Holy magic.
