Hello, I am working with a Lenovo V570. It has Windows 7 Service Pack 1 (64-bit). Has an Intel Core i5-2410M CPU @ 2.30 GHz and 6 GB of ram. I left my computer running when I went to work yesterday only running "Team Viewer 7" program so I'd be able to remote control my pc from my phone if needed be. When i returned, my computer wasnt completely frozen, however not allowing me to run any programs (example: Click the firefox icon, and my cursor would turn into a circle temporarily, then stop loading completely), control panel just freezes, and ctr+alt+del does nothing. Therefore, I restarted my machine and after the startup process, the same problem occurred. I then went into "safemode with networking" and everything works fine. So I went into my startup setting and did a clean boot. Restarted my computer with the clean boot and the problem STILL occurred. Since then I've ran Norton Antivirus and it found and fixed 2 viruses and 55 odd cookie trackers, however my problem still occurs. I cant re-install windows ONE: because bestbuy didnt include a windows 7 disc with my pc, and i have a very small budget to purchase a new windows 7 disc. TWO: because I have my school documents and many programs that i would NOT like to re-install. Any advice would be very helpful. I swear im about 30 more minutes from throwing this laptop out the window. (Im definitely a linux fan). Been working on this problem since i got home from work yesterday. Thank you in advance for any suggestions given.
