What are you seeing other than this? Are there other problems you see? When do you see this? I have worked on older optiplexes and the lights are yellow at different times.

A steady or Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

If the power light is b linking green that usually means the pc is in standby mode. Press a key on the keyboard or move the mouse to resume normal operation.

parental control is usually at browser level settings open that up and make adjustments might be under security


other parental controls are usually on user level on pc's but if you are the only one using it and not a child, then that's most likely NOT what you are asking

If it shuts off randomly it could be to things it could be power suply or virus. i would first off make sure that there is no viruses. make sure u run a virus scan and there is no viruses. if it turns up none i would look into a power suply. if it still shuts off i would look into making sure the heat sink on your cpu is seated correctly and has good heat sink and fan as it could be over heating

95% sure the computer did not overheat, if it did overheat it will shut down by itself to prevent itself from overheat damage. Crashes or computer freeze could result in lagging due to unpowered computer component. When multitrask as you said, some newer software such as games, burners, media players use alot of memory and cpu power and for that sake the cpu will take more time to process these instruction from the software, Most likely with a optiplex 740 you are dealing with dual core, and the promblem can be associated with your memories. Multitasking is memorie hungry. So you may want to upgrade your memories, if not considering purchasing a more powerful computer to handle those task you are using. Also as a advice you may want to defrag your harddrive to make seeking speed faster.

A solid amber power LED indicates a problem with the motherboard, or something attached to it. (I've seen a bad mouse cause a no post before) Disconnect all cables except power, turn on system see if any LED change. If using a UPS, connect power direct to the wall. If still no change, open case, remove any expansion cards, try again. If still no go, disconnect power cables to all drives, try again.
If still no change, then replace the motherboard
