|karanDAprogrammer, that is horrible advice! You have absolutely no idea if the problem is virus related or not, especially based on the minimal info provided.|
bhushan069, you do NOT have to reinstall the OS. Tell us why you were testing the memory in the 1st place. Was it new memory that you wanted to confirm was good? or were you having problems & were testing the memory to see if it's the possible cause? Are you saying your system will no longer boot up since the testing?
