Thanks a ton Kory, however I have already done that.
Why I sought your views on re-installation of Windows is on 21st evening while I was downloaeding a few files, my Laptop first hanged and then displayed the Crash message and re-booted in Safe Mode. Post that I rebooted and started facing the following problems:
1. Skype stopped working on Video calls with the message that there is NO webcam found
2. The MS Word displayed error message for Normal.dotm, which is not a big thing and since taken care
3. Every time I open MS Excel it prompts me to click OK on the message box "stdole32.tlb"
4. Every time I boot the machine I get the message to run the Net.Exe file
5. Last but not the least the Laptop has become slower and booting time gone up by 50% to 110 seconds
Look forward to your advise/guidance
God Bless!
