Startup Repair cannot repair this computer automatically


Try booting into the Safe Mode and check if the issue persists.
Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. The words Safe Mode appear in the corners of your monitor to identify which Windows mode you're using.
1. Restart your computer. Click the Start button, click the arrow next to the Shut Down button, and then click Restart.
2. Do one of the following:
· If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you'll need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
· If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to start in safe mode, and then press F8.
3. On the Advanced Boot Options screen, use the arrow keys to highlight the safe mode option you want, and then press Enter.
4. Log on to your computer with a user account that has administrator rights.
When your computer is in safe mode, you'll see the words Safe Mode in the corners of your monitor. To exit safe mode, restart your computer and let Windows start normally.

won't boot in safe mode


Starting an IBM Thinkpad T43 in safe mode allows you to troubleshoot technical issues that you otherwise couldn't. Often when a system has a virus or other type of malicious program, safe mode is the only way to locate and delete the problem. In safe mode, only the computer's essential programs are enabled, and only the files necessary to running the system are in use. Learn how to start an IBM Thinkpad T43 in safe mode using a few fairly easy steps.

1.Close all programs and restart the IBM Thinkpad T43.

2.Press "F8" repeatedly after the IBM logo appears, but before the operating system logo appears. If the "F8" key doesn't work, restart the computer and try pressing the "F11" key repeatedly.

3.Press the "down arrow" key to select "Safe Mode."

4.Press the "Enter" key. The computer will boot up in safe mode.

Once you enter safe mode

Right click on c:\ and go to properties and then go to tools -> error checking -> check both the dialogue box and then click ok. You get an option which says do you wann schedule the checkdisk the next time the system starts -> click ok

Restart the computer and allow the checkdisk to execute in 5 stages your system restarts on its own which is normal. Your all application problems are solved.
