I don't know much about computers, but i got mine used about 5 years ago. It worked great up until about last year. It started having issues and for the last 6 months it's become a regular thing to restore it to a restore point because it 'blue screens' it's coming to the point where i can't even use it long enough to restore it or repair it because it blue screens before i can do anything. Then after a while it works again for a few weeks until it decides to start blue screening again. I've scanned it for viruses and it says that it's clean. Should I just buy a new computer? Should I take it to a repair shop and see what they can do?
