A.Bad Power On switch. (Behind the Power On button)

B.Bad power supply

C.Power supply cables have come loose inside the computer.
1.Power supply to motherboard. (20-pin connector on motherboard)
This connector has two pins in it for Soft Power On. The power supply does not connect directly to the Power On switch. The power supply connects to the motherboard, and turns on via Soft Power On.

ADVISEMENT!!
ALWAYS have the computer unplugged from power before reaching inside!

ALWAYS work on a table. DO NOT work on a bed, or directly on a carpet floor. These are high areas for Static electricity! Static electricity will silently burn out computer hardware components. You may not see it or feel it.
Touch the metal frame of the computer case, to relieve your body of static, BEFORE you reach inside.

Dell dimension 3000 doesnt recognize cdrw drive


Drive might have gone bad possibly? Or power the PC down completely push the power button for about 1-2 seconds to discharge the PC then plug it back in and restart the computer. If this does not work and you still cannot see the device. Check the cables and make sure they have not come out or are loose. If this is not the problem then you may try downloading the driver file for it at Dell.com replace drive if necessary. John

Dell Dimension 3000 flashing yellow light


Replace the power supply with a known working one. If it goes away then you know that the original power supply is bad.

If it doesn't go away with the new power supply then you know the motherboard is bad and would need to be replaced.

Dell dimension 3000 desk top, does not turn on ?


It's one of two problems: bad power supply, or bad motherboard. If you are electro-mech inclined, remove the power supply. Take it to your local computer repair shop, and ask for one just like that one.
Reinstall, power up should (most of the time) fix this problem. If still no power, you need a new mb. Return to the shop, ask them to replace mb. This repair should be right around $250.0 - tops. Any more than that - replace computer.
Hope this helps. Either way, if you wouldn't mind taking the time to rate my response, it would be much appreciated!
Thanx and good luck.
