Booting up problem

Not sure if this is the right forum.

However, occasionally when I boot up this system (Windows 7 home edition, desktop PC), in the middle of booting up, it "asks" me to press (on a black screen) the option "Starting Windows Normally." There are other options, but I have to be quick. It only gives me 10 seconds to decide. It I am away from the PC when this happens, it automatically chooses that default.

But, if I am away and if I don't press the enter button on that option, when I come to the desktop screen, after it's booted up, my mouse does not work. I can press the mouse's left or right buttons and it has no effect on the browser, email or anything else on the screen program-wise.

I then have to switch the PC off at the plug (the Start and Shut Down buttons don't work either).

If I press the enter button (because I happen to be in front of the screen for that 10 seconds window) on the Starting Windows Normally option, all is then well. I can use my PC again. But I need to be here to press that enter button, which is the problem. And why this screen comes up at all is a mystery.

There is clearly an error. It only occurs occasionally when I switch the system on. Someone suggested an issue at the BIOS level but he's only guessing and I have no idea what do do.

I guess doing a start up repair should help you on this..

Next time reboot the computer and tap the F8 key repeatedly, on the Advanced Boot Options
menu choose Repair My Computer, accept any offered Repair, if not click through to Recovery Tools list to run Startup Repair a few times.

Check optional Windows Updates to make sure you have the latest mouse driver and all important updates.

If this fails, enter Device Manager to Uninstall the mouse driver, reboot computer to let it reinstall. Driver Install - Device Manager

Thank you. Can I go to Safe Mode for this? I am not technically sophisticated, but I do know that fiddling with BIOS if you aren't sure can lead to bad things happening to a PC, including system shutdown if I press the wrong button, etc. Would Safe Mode enable this procedure to be conducted safely?

In addition, if it does go for repair, what's your thoughts on the possible cause of this problem?

Nothing was said about entering BIOS or the need for Safe Mode. Please follow the steps I gave and if you have any questions about those specific steps and not imaginary ones, please ask back.

Thank you again. I know that with the BIOS system, you have to be cautious and careful.

I've gone to:

If this fails, enter Device Manager to Uninstall the mouse driver, reboot computer to let it reinstall. Driver Install - Device Manager

But all it mentions up there is XP, or updating to 7 from XP.

On updates, I have the Windows updates (checked today) and would that include the mouse update? When this fault occurs I can move the mouse on the screen, but it just won't open anything up.

I provided the link to show you how to access the Device manager. Open the mouse driver, click on Driver tab, and choose Uninstall, then use the computer Power Button to shut down and restart to reinstall mouse driver.

Okay thanks, and I will try it when I have a bit of time. As a matter of interest though, there doesn't seem to be a Power Button here. Unlike my earlier PC, this is a different setup. Tried to find an on/off button on the PC tower but no luck.

Are you serious that you cannot find a Power button on your PC? Check the plastic molding to see if it is recessed into it so that it isn't visible. Check the top and front carefully inch-by-inch. I've never heard of a PC not having a power button at all. And it isn't good to use the power cord or even the PSU switch.
