Hi miecias,
You may download the drivers and BIOS through a different system and transfer them on a CD or USB flash drive. Connect that flash drive to this system and update the drivers and BIOS.
Also, you may try booting through Last Good Known Configuration. Here are the steps:
- Restart the system and immediately start tapping the 'F8' key to enter the 'Windows Advanced Options' menu.
- Use the Arrow keys to select Last Known Good Configuration (your most recent settings that worked), and then press ENTER.
Note: After you start your computer by using the Last Known Good Configuration feature, changes that were made since the last successful startup are lost.
If the above steps doesn't work, you may try restoring the system back to factory defaults. Please back all the data before you restore the system back to factory settings as this process may lead data loss. You may refer to the link http://dell.to/12VESsX for steps.
Hope this helps. Please reply with the findings.
