Troubleshooting Errors:
No operating system found? -
- the harddrive is physically damaged or has a disconnected/damaged cable
- the system or the boot files have been corrupted or missing
- the master boot record is damaged/changed
-computer virus
Try to boot to a startup disk and type sys c: and /or run windows setup to replace the system and boot files. -
Troubleshooting Errors:
Error in CONFIG.sys line xx? -
Command.com file was deleted or renamed, is the wrong version, or has a damaged header.
Solution - use a startup floppy (must be the same version or later as the system you are trying to boot to). Type sys c: at the a:\>prompt and press enter. Reboot -
Troubleshooting Errors:
HIMEM.sys not loaded? - The HIMEM.sys command line in your config.sys file must appear before any commands that start programs or device drivers that user extended memory. If any of these other programs or devices try to load before HIMEM.sys is loaded you could receive the error message
-
Troubleshooting Errors:
Missing or corrupt HIMEM.sys? - The file may have been deleted from the c:\windows\command directory, or there is a line in config.sys calling on a different version of HIMEM.sys
-
If you do not have much free hard disk space your __ file will not be able to expand which can cause your computer to run slow.
What is this file? -
Swap file
Not enough free space also causes your swap file to swap between physical memory ad the hard disk more frequently, which increases the chances of general protection faults -
NT Boot issues
The boot menu disappears? - If you want to set up a dual-boot system, you must install the alternate operating system before you install Windows NT. If you install windows NT first and then install another OS, it will overwrite the boot sector, and then the PC will no longer look for the NTLDR file. To correct the problem install a new copy of Windows NT to a different directory. Doing so will make NT bootable. You can then edit your BOOT.ini file and remove any references to the new copy
-
NT Boot Issues
BOOT: Couldn't find NTLDR Please insert another disk? - Your boot sector is okay b/c it still points to the NTLDR file. However, your NTLDR file is either missing or damaged. To correct this problem, replace the NTLDR file with a backup file or installa new copy of Windows NT to a different directory
-
NT Boot Issues
Windows NT could not start b/c the following file is missing or corrupt:
\system32\ntoskrnl.exe Please reinstall a copy of the above file? - This problem usually occurs b/c the BOOT.ini file points to the wrong location for the Windows NT operating system of NTOSKRNL.exe is missing or damaged. Copy the file from a backup or install a new copy of Windows NT to a different directory and copy file
-
NT Boot Issues
I/O Error accessing boot sector file ulti(0)disk(0)rdisk(0)partition(1):\bootsect.dos? - This error indicates that the BOOT.ini file either points to the wrong location for the BOOTSECT.dos file or that the BOOTSECT.dos file is corrupt
- In windows 98 how do you get to Dr. Watson?

1. You can go start menu, click run, type drwatson
2. Go to start menu, programs, accessories, and system tools, then click system information. Select tools menu and click Dr. Watson - What collects detailed information about the state of your system at the time of and slightly before and application fault?
- Dr. Watson - intercepts the software faults, identifying the software that faulted and offering a detailed description of the cause
- How do you get to Dr. Watson in Windows 2000?
- Start, run, type drwtsn32. To start from a command prompt, change to the root directory and then type drwtsn32
- What is it called when a program tries to access a portion of memory that has not been allocated by Windows or is already being used by another program or TSR?
-
General Protection Fault
Solutions
-Run scandisk/defrag
-Remove any TSRs or programs which were running before the GPF
-Remove and reinstall the program that caused the GPF
-Disable power management and screen savers - This is caused when windows or a program attempts to store or call a segment or block of memory that does not exist?
-
Invalid page fault
This could happen b/c of bad memory or the program is incompatible or corrupt
Are generally caused by program incompatibility, overheating such as the cpu cooling fan not operating or other hardware/software issues - What is an operation requested, which is not understood by Windows or the CPU?
-
