Question about Dell Dimension 8400 PC Desktop

1 Answer

Start up will not retain memory for fire wall setting.

Most often (not always) when I turn on my Dell Dimention 8400 computer, I have to go to the control panel and click the box for my microsoft fire wall to be activated. Why will it not hold the memory to keep the fire wall active?

Make sure you haven't installed a third-party internet security suite that includes a firewall. You should only use one firewall on your system and some third party firewalls automatically turn the windows firewall off. But your security center should show that you are protected by a firewall, nevertheless.
This behavior can be an indication of malware installed on your computer...
I recommend you go to windows update and make sure you are current with all critical security updates for your system, then go to www.malwarebytes.com and install their AntiMalware software. Scan your system and fix any problems it detects.
Then see if your system retains the firewall settings.
I thought there was a MS knowledge base article on this that had something to do with sp3 and a bug fix but I can;t seem to find it right now...
If I locate it I'll post back with a comment...
In the meantime, if those first two suggestions don't turn anything up, I'd run chkdsk on your system and see if it finds some file corruption.
See this article and this one

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!

How do I replace low battery in dell dimention 8400


The Dell Dimension 8400 has a CR2032 battery inside the case. If your computer is saying that it is dead when you turn it on, this is a quick fix. A new CR2032 battery can be purchased from any general store (Best Buy, Walmart, Radio Shack) for about $4. Open your Computers case. There are buttons at the top and bottom that let it open like a book. You will see the battery somewhere on the main board. It looks like this. Use your finger nail or a pen to push the clip holding it in place out of the way. Replace with you new battery and close everything up.

Dell pc dimensio 5150 wont boot up


If the power light is blinking amber - The computer is receiving electrical power, but an internal power problem might exist.
Ensure that the voltage selection switch is set to match the AC power at your location (where power cord goes into unit).
Also try simply unplugging the unit from the wall outlet for a minute then plug it back in and boot it up.
