How can i go to bios setup


Straight from the Dell website:
  1. Turn on (or restart) your computer.

  2. When "F2 = Setup, F12 = Boot Menu" appears in the upper-right corner of the screen, press .

If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft Windows desktop. Then shut down your computer and try again.


I hope this answers your question!

My dell 2400 wil run for sometimes 10 sometimes 45 minutes and the the monitor loses signal and the power light is amber and the hard drive light is green, the diag. lights in the rear are either off or...


The power supply may be going out. Go to the Dell website, select support, enter your service tag number and find your symptom to determine the problem. The lights in the back will help you isolate the issue by cross referencing it to the lights that are lit and not lit.

Unexpected restart


Hello rjblittle

I've seen this problem with dell's before, A/B diagnostic lights appear as as yellow lights is a memory error. Most techs and I have found it to be bad memory. I would suggest replacing the memory or before doing that take the memory out and try it in different memory bank slots to see if that helps.

hope this helps

Dell 2400 dimension desktop


When you said "I think its a memory problem" your right, you need more of it. Try adding more RAM. It's really cheap now a days, especially for the 2400. Memory is available everywhere. While this is not an endorsement of their site, Computer Memory Outlet.com has about the cheapest RAM available and they are reputable and reliable and orders usually ship next day. I personally get all my memory from them.

p.s. They have an on site utility that will scan your computer and tell you the exact RAM you need and the maximum RAM you can add

Can't get pass the background screen when pc load


The sequence is:
a) The Dell bios splash screen is displayed,
b) the screen will go black,
c) the disk activity light will flash for about 5 - 7 seconds, then will remain off.
d) you force a power off,
e) wait a few seconds,
f) then turn the machine back on.
g) The bios splash screen is displayed,
h) then a black screen with white text is displayed, reporting that Windows was not shut down nicely and would I like to boot into safe mode or safe mode with networking, or others.
g1) If you choose Safe Mode, Windows will boot up successfully. If I restart, the computer will usually (probably) boot into Windows fine.
g2) If you choose Boot Normally, the computer will usually (probably) enter the black and hung state.
see if that helps and the if possible do a do a system restore to when the system was working correctly.
