I Recommend Replacing Your RAM Because It Can Cause All Sorts of Issues,For Instance,Youtuber By The Name Thiojoe Mentioned In One Of His Vids That Was Getting A Weird Graphics Glitch But It Turned Out To Be a Bad RAM Stick,To Test Your RAM,You Can Use The Windows Memory Diagnostics Tool,Just Find An Online Tutorial To Use That Tool,And If You Get Errrors,Replace The Faulty RAM Stick,If You Have 2 RAM Sticks For Example,Remove One And Re Run The Test If You Don't Get Errors,This is Your Good Ram,And Do The Same For 4 Rams Keep Adding One By One Until You Get An Error The Last Ram you added is faulty,and so on and so forth until you find your bad ram stick
Note:if you have 1 ram stick and you get an error,just replace that ram stick and in case your wondering,no, you cant fix a ram stick
