Default dell desktop contstantly shutting down

My dell dimension 2400 keeps shuttin off and orange light on front comes on solid. The diagnostic lights on back all remain green. Someone suggested the motherboard They said you could tell by the capacitors would look like they come out of the freezer. Well the capacitors look fine. What would the next step be for checking out problem a little further. Thanks and any help will be greatly apreciated

Generally the F1 F2 option you see is because the cmos has reset to the defaults meaning it goes to the date/time of manufacture instead of today's date/time. If you go into the bios and check the date/time and it's to the original date/time the you should replace the cmos battery, usually a #2032 coin size battery on the mother board, you can pick up the 2032 battery's almost anywhere they sell batteries. You'll need to reset the date/time after you replace the battery, always disconnect power and ground yourself before you go inside your pc


The probable reason your cmos battery died is because the power was off for an extended time. Replacing this battery will keep the right date/time but it most likely will not solve the original problem

I have a Dell 2400 on my bench and it does have a 4 pin power connector on the left side between the cpu and i/o connectors on the back. you'll need to remove the fan hood on the inside to see it

enter means that you tap the enter key on your keyboard to make adjustments

here's a list of the fault codes for the LED lights on the back and it also has a listing of beep codes too

One more quick question. Can you go into setup and set date back a month or so when it was working. Thanks

It could be over heating problem, take off the heat sink clean all dust apply new thermal paste, make sure fan is in proper working order. this should sort the problem.
