Does it give you the error before or after entering Windows? If after, go to "Start" and then in the search field type in CMD to load the "Command Prompt" window. Make sure, if you are doing this not logged in as Admin, that you right click on Command Prompt and choose load as Admin to start it. Once it is loaded type in "chkdsk" (without the quotes) and let it run. See if it mentions any errors.
If no, or you can't get enough time in Windows to actually run it, then try starting the computer in "Safe Mode" to see if the problem occurs then. If the errors don't occur in "Safe Mode", then you probably have something running on the computer that is causing the issues, which is something that can't auto run/start in "Safe Mode". If this is the case, you need to figure out what it is, and uninstall it. That also applies to viruses, malware, etc. If the problem still occurs in "Safe Mode" I would start to wonder if your hard drive is failing.
How to enter "Safe Mode" when booting the computer.
In Windows 8 and 10...
As your computer restarts, press F8 (possibly a few times) to enter "Safe Mode"
a. Press the "F4" key to Enable "Safe Mode".
(The computer will then start in "Safe Mode" with a minimal set of drivers and services.)
b. Press the "F5" key to Enable "Safe Mode" with Networking.
( Once "Safe Mode" with Networking starts, Windows is in Safe Mode, with additional network and services for accessing the Internet and other computers on your network.)
c. Press the "F6" key to Enable "Safe Mode" with Command Prompt.
(In "Safe Mode" with "Command Prompt" starts Windows in Safe Mode, with a Command Prompt window instead of the Windows interface. This option is mostly only used by IT professionals.)
Now sign in to the computer with your account name and password. (If you have one set.) When you are finished troubleshooting, you can exit "Safe Mode" restarting your computer.
In Windows 7/Vista/XP...
1. Immediately after turning on the computer, or restarting it (usually after you hear your computer beep), tap the F8 key, repeatedly, in 1 second intervals.
2. The computer will then display hardware information and run a memory test.
3. Next the "Advanced Boot Options" menu will appear.
4. In the "Advanced Boot Options" menu use the arrow keys to select "Safe Mode" or "Safe Mode with Networking" and press ENTER.
