My dell dimension 2300 powers on,but nothing shows on the screen and i just got a brand new power supply for it.Also when i turn it on the power light isn't lit and it sometimes works.

It Sounds Like Your PC Is Defective Because First Of All There Shuld Not Be A Power Button Connector To
Remove In The First Place And Second The Power Button is What You Turn On The PC With So It Is
Best To Replace The PC With One That Uses An Intel Pentium 4 Prosser!

if you are using xp, boot from xp cd and
copy from i386. this file "lsass.exe" to the follewing location and restart

c:/windows/system32
C:\WINDOWS\system32\dllcache (this is hidden file also protected os file)


hope this is usefull

try to reformat your harddisk

Check all connections, to the motherboard, and also to the wall Verify that the power supply is actually switched into the ON position at the rear of the computer.

The motherboard chipset of the Dell Dimension 2300 Desktop PC, will not support a processor with an 800MHz Front Side Bus frequency rate.

Only Intel Pentium 4's that use a Socket 478, 1.75 Volts, and a maximum of a 400MHz FSB.

The Intel Pentium 4 HT 3.0GHz processor has an 800MHz FSB, (As you have already stated), and uses 1.475 to 1.55 Volts.

The motherboard chipset for that Dell Dimension 2300, is an Intel 845GL.

This list on Wikipedia, shows you parameters the Intel 845GL chipset supports,

Not a good outcome, sorry. Just stating the facts.

I've run into the problem several times and it can be both.Your best bet would be to try the power supply first, being the cheaper and easier of the two. If you have another desktop you could try swapping the power supplies to test (make note of which plug goes where, it's fairly simple as long as you pay attention).

If you don't have a spare then it's possible a local tech store would have one you can purchase or pay them a small fee to test for you.

If swapping them doesn't work then it points at the motherboard.

Hope this helps :)

go to this link for help on th codes. You might have the wrong type of memory or the memory could be bad or maybe it's not seated properly.

I don't know what TRIPS out sounds like, but there are number of different things that could make sounds when powered up. Let me know what and where the sounds are coming from. I am including a link for delll support for your system. Let me know if I can be of any more help. Larry

thats really low. are you sure you don't mean under. my computer doesn't go under 800x600. Max resolutin is 1280. Are you sure you're downloading the right monitor driver, because that hapened to me before, but it was because i had the wrong driver.Nothing is wrong with the monitor!!!!

Please Rate!!!

Make sure all the drivers for the new processor are installed.

Also, does the BIOS show the new CPU?
