Can't fix computer

[theirish]

I have had an Asus computer for a year now and recently started having issues with it. The computer will work for a while but about 30 to 40 minutes in it says that the computer memory is low and will not load anything. I also can not update anything for some reason. I have tried just about everything from Dism scans (which result in errors) to sfcscannow (which says that there are errors but it can't fix. I have even tried updating and hard reseting windows 10 but it always says "something went wrong" and will not update. It also will not let me update the bios. Any ideas as to what the problem may be and how I can fix it?

Hard to tell without further information. Can you open the taskmanager and tell us the name of the process that is using up all your RAM?
