Hello! I got onto my computer a few weeks back and a few things have gone wrong. It is unable to get onto the internet (connection failed though my internet does work because i can get on xbox live), when shutting down it will say "Shutting Down" but it will never power off unless the power button is held, and the monitor will go dim at random times.

System restore did not solve any of these problems. I use a Linksys wireless card if that helps.

Any help would be greatly appreciated! Thank you

The Dell XPS400 is I think a desktop. It may be a power supply problem.
Have you done anything at all by way of altering registry settings or any files that yoiu would not normally use.
The original DellXPS400 had only 512mb ram with a 3.2gHz processor.
I do not think the small amount of ram is the problem even if it has not been upgraded.
Pls come back with any details of ANYTHING you have done, other then normal use.

I have altered some things that i'm not positive i can remember, only for trying to fix the problem though, not prior to the problem

[justthereb]

I have heard of power supply problems though.

How many USB devices do you have plugged in

[justthereb]

3- Mouse, printer, keyboard

[Macboatmaster]

Is the wireless card a Pci card or a USB wireless adaptor

[justthereb]

Not positive (computer novice) its a linksys wireless card. so i'm guessing a Pci card

What anti-virus, spyware, etc programs do you have on.

[justthereb]

McAfee but i dont often utilize it.

The Dell has an ethernet port. It is integrated on the motherboard, at the back of the computer is a
port to plug in an ethernet cable from your router. Can you do that, rather than trying wireless.

[justthereb]

I have done this but all what happens is a get a limited or no connectivity, i still cant get online after having tried this

[Macboatmaster]

That is because YOU are still using your wireless. With ethernet cable plugged in.
Go to Start
Control Panel
Network Connections
Do you have two connections shown. If so
Disable the wireless connection. DO NOT REMOVE that connection, just disable it.

[justthereb]

my wireless was already disabled because i cannot enable it. same thing- limited access- no internet

Do you have another computer on which you can get on the net to download a file to a USB pen and then put it your computer.
