My computer turns on in the middle of the night

Question: I noticed recently that my computer runs in the middle of the night. I turn it off before I go to bed, but it starts up at around 3 in the morning. What is it doing and how do I turn it off? Do I have a virus?

Answer: Viruses don't typically work that way - they tend to inflict damage right away, or in response to certain actions (such as clicking a link in an email message).

The most likely reason your computer is turning on in the middle of the night is to check for Windows updates, especially since the default time for doing this is - wait for it... 3:00 a.m.

By default, Windows Update runs at 3 in the morning every day to check for new updates, and will turn on your computer even if you've turned it off. You can check your Windows Update settings by opening the "Windows Update" application in your Control Panel.

To get to your control panel, click your Windows Start button and you should see it on the popup menu. You can also type "Windows Update" in the search bar after clicking the Windows Start button.

You'll see the default setting which is "Install updates automatically" and the default frequency of "every day" at "3:00 AM". Click the dropdown and choose any of the other options, such as "Download updates but let me choose when to install them".

That will keep Windows Updates from turning on your computer in the middle of the night, which should also extend the life of your computer and save on your electrical bill over time.

Connecting a Linksys Wireless Router to a Comcast Modem

I upgraded my wireless home network this weekend from an old Netgear 802.11b router to a shiny new Linksys WRT120N router sporting the latest 802.11n technology, and a much sleeker design.

The network speed difference is very noticeable and significantly faster on the newer router, and the units were on sale for only $39 at Fry's so it seemed like a steal of a deal... until I tried to install it.

I have Comcast internet at home with a standard-issue Motorola cable modem, and it turns out that Linksys routers don't naturally connect directly with these modems.

The Network Magic software that comes with Linksys routers failed on the first setup screen with an "Error 321", claiming it could not detect my ethernet network adapter. Apparently the Linksys routers require you to connect through a separate router that sits between the Comcast modem and the Linksys router (or at least that's what I found hidden somewhere in the documentation) - and in fact, it worked fine if I connected through my old Netgear router to the Comcast modem.

I was also able to connect directly from my computer to the Linksys router, which I was able to verify by running ipconfig and seeing the IP address assigned by the router. I was also able to log into the router's admin console screens by opening a web browser and entering the IP address of the router - http://192.168.1.1 using admin/admin for the username/password.

Copy data files from an old hard drive to a new system

Question: My dell 8400 tower went down, replaced power supply and ..nothing. How can I get everything off the hard drive, install into another tower, or take it somewhere to download to external drive?

Answer: From what you've described, it sounds like your motherboard is probably fried. Since the Dell 8400 series run an old Pentium 4 processor, it's probably not worth bothering with trying to replace the motherboard and you're better off trying to get the data off the hard drive and replace the system altogether.

You have a couple options for doing this. You can hook up the hard drive as a slave drive in your new system, or you can use an IDE adapter that plugs into a USB port and treats your hard drive like an external USB drive.

Either way you'll need to remove the hard drive from your old system, which is easy to do. Remove the screws from the outer casing (some cases let you slide the side off without removing screws) and locate the hard drive. There will be a flat thin cable about 2 inches wide connecting it to the motherboard. Remove the screws holding the hard drive to your case (usually 2 on each side) and then remove all cables and power cords going into the hard drive.

IDE Adapter

The easiest way to get data from your old hard drive onto another desktop system or laptop is to connect it using an IDE adapter. The adapter will connect your hard drive with your other system's USB port, and will let you copy files over just like it was a USB flash drive.

How do you change the desktop wallpaper for multiple computers on a network?

Question: Suppose we have a networking in a LAB and i have total rights over all other systems on the LAN. Now how to change the wallpaper of the system which is there on the LAN???

How to copy the contents of one hard drive to another

Question: I have a computer with a 20GB drive and would like to install a 80GB drive that I have, as the 20GB drive has under 1GB remaining. Can I use imagining software to copy all Programs, files, and folders (including system files) from the old drive to this bigger drive, and make it be the startup drive? What would be the best software for me to use?

Answer: Yes, you can copy the contents of one hard drive to another, as long as the drive you're copying to is as large or larger than the old drive, and as long as you have the right software. You can even copy installed programs and the operating system over to the new drive, so you don't need to spend money on another Windows license or worry about re-installing programs.

Both hard drives will need to be connected to your motherboard using a standard IDE cable. Two hard drives can be connected with the same IDE cable - just make sure that the old drive (master) is connected to the first available connector slot, and the new drive (slave) is connected to the middle slot on the cable.

You'll need a software program to copy over the old hard drive's contents to the new hard drive, also known as "ghosting" or "disk imaging".

I'll discuss 2 disk imaging programs in this article - one that's both a ghosting program and a backup program, and another lighter-weight solution that only handles disk copying (and is more affordable too).

Norton Ghost

Norton Ghost is a well known and trusted program that will duplicate your old drive directly to another drive.

Norton's step-by-step wizards make it easy to copy the contents of your old drive to your new hard drive, even if you're not super technical or very good with computers.
