.Did you try the usual cleanup noted at http://forums.cnet.com/7723-6122_102-569818/getting-ready-to/?tag=contentBody;threadListing
I have a Dell Inspiron 1720 running the Vista operating system. I purchased and downloaded system mechanic which I run about once a week. Recently during the optimization process the computer froze and will not move forward/re-boot. When I cut it off and than back on it will come up to the sign in page, freeze again, and will not move any further. I have contacted systems mechanic and received no assistance at all. Can anyone help me with this problem. Thank you!
