Regarding the above i would like inform you that i have over-come to that particular issue.
The story was that during the internet using i download a software after using i found that it it useless so i un-installed that software,while i was un-installing a message receive(a list of my installed software will also be delete)I just ignored after restart I could not find my DVD.Ram is My computer and contated to Microsoft.
Mean while I pray to Allah being a muslim and request for soulution.
Mean while I re-store Winmdows and fouind that the reason is some where else.
I checked my BIOS and found that all Biose setting was disturb.
I adjust the BIOS and restart and foun each any every hardware of My computer.
This was the true story and end too.
Thanks and regard for taking time.
