Urgent matter forgot password

Hi Junaid

Can you please supply a little more info so that we can try assist you.

With the little info we have to work on maybe I can suggest you need to make a bootable operating system to use in your device connected to your USB port to boot the machine.

Hope this helps

Kind regards

Reset the BIOS or put recover from last state to OFF

you will need to get to your bios setup and do a comprehensive check

can you get into the bios at all

You cant.. Unless the nvidia card you added has two video OUTs. Plugging in a aftermarket card causes the motherboard to disable the onboard video..
If your nvidia card has two "outs" then you can use two monitors... most newer nvidia cards support this. sometimes it requires an adaptor, but usually it was included in the box

go to dell.com
put in your model number and download the instruction manual and any driver you are looking for.

Possible failures are:

1. Powersupply failure
2. Motherboard failure (Check the capacitors for popped ones)
3. Front I/O Panel
   

open your cpu remove the battery on the motherboard restart the pc without battery and refresh the bios by the jumper or a switch present near to the battery.

Change the resolution right click over your desktop blank area click properties and under setting you can adjust screen resolution

Your cd Rom is also not working properly

Hi

OptiPlex GX260 can be Small Form-Factor, Small Desktop or Small Mini-Tower. Compatibility with PCline 5.1 PCI depends on the profile of the PCI Card and the Profile of your OptiPlex.

GX260 Small Form-Factor is compatible with Low-Profile PCI Cards only. GX260 Small Desktop and Small Mini-Tower are compatible with standard PCI Cards. (Small Mini-Tower however uses a PCI Cage).

Check OptiPlex GX260 Systems User's Guide - http://support.euro.dell.com/support/edocs/systems/opgx260/en/ug/index.htm
From here you visualize the 3 form factors. Also there is info and steps to install PCI cards.

NB:
1. Generally, upmarket PCI cards are standard height. Some manufactures supply a metal piece to allow it to be used in Low-Profile or Standard Profile.
2. Driver software needs to be installed after the hardware is installed.
