Hello friend, this is the most unexpected problem they have faced in the operating system Microsoft Windows XP Service Pack 3. Every time I try to upload some photos or pictures below, the system automatically locks. I do not know the rationale behind that, but I have to solve that problem. I am running Win XP Pro SP3, 1GB RAM, video card and HD and 180 GB hard drive. I hope someone has also faced this problem and solved the error. So please help me solve this problem.
