Other SUWIN errors

SUWIN issues can occur because of any of the following reasons.

  • Computer is set improperly.
  • Incorrectly configured Windows.
  • Memory management software is incorrectly configured.
  • Computer has a GSI BIOS.
  • Double-buffering is required for your hard drive, but is not enabled.
  • Cirrus Logic video card driver installed that is incompatible with Windows setup program.
  • There is an antivirus enabled in your computer’s CMOS settings.
  • More than 1200 TrueType fonts installed on the computer.
  • Computer using mismatched memory.
  • Faulty hardware or motherboard.

Incorrect BIOS settings, or system is overclocked

Ensure that all the correct settings are set in CMOS setup. SUWIN errors can occur if the CPU, RAM, cache, hard drive (bus mastering) or other hardware devices are configured improperly.

  • How to enter and exit the BIOS or CMOS setup.

Consider trying the following recommendations.

  • If you have overclocked the computer, set the overclocked device to its proper setting.
  • Disable cache.
  • Disable UltraDMA.
  • If available, you may want to consider restoring the default values if an available option.

Computer date is set improperly

Ensure that the date is properly set on the computer.

Incorrectly configured Windows setting

If you are running the Windows setup from within Windows, exit from Windows or use a bootable floppy diskette and run setup for Windows from an MS-DOS prompt.

For additional information about creating a bootable diskette, see our boot disk guide.

Memory management software is incorrectly configured

If memory management software is installed on the computer verify that it is configured properly by temporarily disabling the software.

Computer has a GSI BIOS

If the computer has a GSI BIOS, contact the computer or motherboard manufacturer for additional support on resolving this issue.

Double-buffering is required for your hard drive, but is not enabled

If the hard drive requires double buffering, make sure it is enabled.

Cirrus Logic video card driver installed that is incompatible with Windows setup program

Run setup from MS-DOS instead of through Windows.

There is an antivirus enabled in your computer’s CMOS settings

Some computers may have a feature in the CMOS setup, which allows the computer to scan and help prevent computer viruses from infecting the computer. Make sure this option is disabled in CMOS if found. If this allows setup to complete, this feature can be enabled after the installation of Windows.

More than 1200 TrueType fonts installed on the computer

If you are upgrading Windows from a previous operating system and more than 1200 True type fonts are installed on the computer, you may experience a SUWIN error. If more than 1200 True type fonts are present on the computer, try deleting or moving the fonts and then run setup again.

Computer using mismatched RAM

If the computer uses mismatched memory, for example, EDO, non-EDO, or different memory speeds it may be causing your issue. Consider removing the added memory from the computer if the system has enough memory for the operating system being installed.

Faulty hardware or motherboard

If the above recommendations do not resolve the issue, contact the computer manufacturer for support, service, or replacement.

If the computer is a custom built computer, consider replacing or removing peripherals in the computer that may not be required as they may be defective. For example, remove any PCI or ISA cards, including any network cards, sound cards, and modems. If the computer has an onboard video or sound card, disable that device in CMOS setup, if the option is available.
