Hello awesome MDL members, I had a virus attack after which I performed a clean install of the windows 8.1 Ever after that, when I boot-up my PC I can't see any Bios hotkeys but on the contrary they do show up when I'm re-starting. Also the Time gets manipulated every time I do a shut-down. I Initially thought it might be because of the battery but then I noticed it getting out of sync every 1/2 hours even when my PC is running. All my apps have gone rouge because of this, my email grouping is destroyed and other strange things happening because of the time getting out of order. How can I resolve this ? Any help will be greatly appreciated. Thank you.
