Hi, This is a serious problem am facing through. I have a desktop system that is powered by Intel pentium 4 processor installed with windows xp service pack 2. Now I have installed a program or a software you can say, called Registry Mechanic. It actually performs system cleanup and maintaining the registries in a proper way also removing threats. But after when I did install this application my system is getting crashed every now and then. Please help me out. Thank you.
