I noticed lately that my desktop computer is too slow and frequently frozen for minutes. I don't know why because I haven't made any changes since I bough this last year. I just have uploaded new videos of my son which I play from time to time. I didn't not install new softwares or hardwares. I religiously scan my files for possible virus infection and I'm 100% sure that my computer is protected. Maybe it's time for pc tune up, I need those tools that will help me to run tests in order to ensure that my pc is okay if not be given recommended fixes for problems found. I'm not sure if hubby did something, I will ask him if he downloaded anything or installed new software because they might be the culprit.
