Yes you can, look for the time and date settings and follow the directions to change the time and date correctly.
I think its page up and down keys to change, havent touched a dell 2400 for awhile.
Save your settings and be sure to reboot.
if the changes were not saved and storing correctly, follow through with joes comment about the cmos battery problem.
Go back to best buy, take your cmos battery with you, tell them you need a replacement.
They should be able to get one if they have it in stock.
Also if your computer persists to shut down after 2 or 3 minutes of booting up.
Do what wilson suggested and get your cpu grease reapplied or risk over heating damages.

Hmm I don't know what may going wrong with your dell.
The only thing I would check now is the cpu and put on some new grease.
Also check inside the case and make sure the mobo is seated and grounded right.
If any of the wires are loose and dangling around, that maybe the real problem and stopping it from booting.
Don't know why most dell desktops have that in some weird issue. >_>

I personally suggest you look into gutting out the old mobo/cpu/ram and go for something more up to date.
If your interested set a price budget and I'll see what I can get you.

you can also try another power supply except this time connect the 4 pin behind the fan shroud to the motherboard

That's because newer boards have a 24 pin connector. They make the main board rail from the power supply universal for 20 and 24 pin boards
