I have an HP Pavilion dv6-2157sb running Windows 7 Ultimate SP1, 64-bit OS. I bought it in the summer of 2010 for law school. The laptop has served me faithfully through law school. After almost three years, however, it began booting up with the time being incorrect. Commonly, the time stamp would be 1/1/2009. At other times, 12/31/2008. Still at other times, 5/1/2013, and finally random dates between 2022 and 2023. I did some preliminary research and decided that the BIOS battery must have an issue, and with the help of my uncle who does IT work for JP Morgan Chase, replaced the battery. Upon doing so, we also went into the BIOS settings and changed the date & time accordingly. This did not help. My "temporary fix" for this has been to connect to the internet, click the date & time, click Change date & time settings, click the Internet Time tab, click Change Settings, click Update now, and the date & time would adjust according to the internet time. There have been instances where closing the monitor lid and putting it to sleep would not cause the time to change when opening the lid and waking the computer up. Upon shut down and start up / rebooting in general, the time & date invariably changes. Once in a while, putting it to sleep and waking it will nevertheless cause the time and date to change, albeit less frequently. Finally, every so often, I'd say once every two weeks, the date & time will change sporadically while the computer is on. At the same time that this issue cropped up, several other things began going haywire; namely, (a) The icons on the bottom right in the task bar next to the date & time would load very awkwardly, with lots of gaps & spaces in between them, and if one of the blank spaces were the wifi/ethernet settings, the internet would not work. My "temporary" fix for this has been to go to Task Manager, end the explorer.exe process, hit file > new task (run...) > type in explorer.exe > hit enter and upon restarting explorer, all the system tray icons look fine and operate normally. (b) more importantly, Windows Update has suffered as a result of this. I noticed on my Windows 7 PC (DELL Optiplex 745) that my Internet Explorer version is v9.0.15. Here, it's 9.0.14. There's a 57.8 MB update titled Windows Internet Explorer 9 for Windows 7 for x64-based Systems. No KB number for it, but always fails with error code 9C48. Even where it somehow is "successful," when I just shut down and it attempts to install during shut down, the update comes back up. I've done extensive research on this problem and found a great thread in the w7 forums here with lots of proposed solutions; absolutely none worked. When I tried installing Internet Explorer 9 as a standalone exe without using Windows Update, Windows informed me via a dialog box that the version of IE I have is newer than the one I am trying to install. After giving up and hiding that update, I yesterday attempted to install Internet Explorer 10. The installation took a long time, but after about an hour, it said it was complete, and asked me to Restart. Upon restarting, Windows gave me an error claiming that it failed to configure windows update and is reverting changes now. This is what happened before with other windows updates related to internet explorer. Please help. Are the two issues related somehow? What should I do? Kindly let me know whether you need any more information; I would be glad to provide it for you. Best regards, Emanuel.
