Last couple days my computer is not loading. It gets to a certain point and then stops. I have to either reset or shut off and try starting again. Then a message comes on telling me the computer shut down because of some problem and will start again in 30 seconds and starts count down. It trys to start but again stalls. Finally 4 or 5 times I get it to load. Am I looking at the final days and be prepared for a burial or is there a common fix???
