Hi sergsco, Check out Page 14 of the service manual for Jumper settings and how to reset passwords or clear NVRAM. ftp://ftp.dell.com/Manuals/all-products/esuprt_desktop/esuprt_optiplex_desktop/optiplex-745c_User's%20Guide_en-us.pdf

Clearing Forgotten Passwords

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.

NOTICE: This process erases both the system and administrator passwords.

Follow the procedures in Before You Begin.
Locate the 2-pin password jumper (PSWD) on the system board, and remove the jumper to clear the password.
Replace the computer cover.
Connect your computer and monitor to electrical outlets, and turn them on.
After the Microsoft® Windows® desktop appears on your computer, shut down your computer.
Turn off the monitor and disconnect it from the electrical outlet.
Disconnect the computer power cable from the electrical outlet, and press the power button to ground the system board.
Open the computer cover.
Locate the 2-pin password jumper on the system board and attach the jumper to reenable the password feature.
10. Replace the computer cover

NOTICE: To connect a network cable, first plug the cable into the network wall jack and then plug it into the computer.

11. Connect your computer and devices to electrical outlets, and turn them on.

NOTE: This procedure enables the password feature. When you enter system setup , both system and administrator password options appear as Not Set—meaning that the password feature is enabled but no password is assigned.

12. Assign a new system and/or administrator password.

Clearing CMOS Settings

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.

Follow the procedures in Before You Begin.
Reset the current CMOS settings:
Locate the password (PSWD) and CMOS (RTC_RST) jumpers on the system board
Remove the password jumper plug from its pins.
Place the password jumper plug on the RTC_RST pins and wait approximately 5 seconds.
Remove the jumper plug from the RTC_RST pins and place it back on the password pins.
Replace the computer cover
NOTICE: To connect a network cable, first plug the cable into the network wall jack and then plug it into the computer.

Connect your computer and devices to electrical outlets, and turn them on.
