Hi MandarGovind,
Did you get any error message when you ran the diagnostics? You can also run the diagnostics from F12 menu:
- Restart your system and keep tapping 'F12' as soon as the Dell logo appears.
- Highlight 'Diagnostics' using up/down arrow keys and press enter.
Please let me know if you get an error code/message.
For 'Diskette 0 seak failures' error, I will recommend you to load BIOS defaults and also disable floppy drive in BIOS:
- Restart your system and keep tapping 'F2' as soon as the Dell logo appears.
- Press 'F9' for BIOS defaults.
- Press 'F10' to save the changes.
- Also, go to 'Integrated Peripherals' and disable 'Onboard FDC Controller'.
- Press 'F10' again to save the changes.
Keep me posted. Please reply for any further questions.
