In a modern Windows OS, when you click Start/Accessories/System Tools/Disk Cleanup you will note a dialog which will eventually present you with choices of files to remove from your computer. These are left over files from various activities and will look something like this:

Disk Cleanup can assist you in removing no longer needed files

Now you are able to select the categories you want to remove, for example, Temporary Internet Files, Microsoft Error Reporting Temporary Files, Recycle Bin, Temporary Files, WebClient/Publisher Temporary Files, etc. Note these are all temporary files. There are also other categories you should normally never select. These include Office Setup Files, Log Files, Compress Old Files and Catalog files for the Content Indexer. Please note Windows Vista and Windows 7 users will have more options available.

If this is the first time you have ran CleanMgr (Disk Cleanup), the initial scan process could take quite some time. These scan’s may take in excess of an hour. Microsoft had provided a way to streamline this process through preferences, but you have to use the Command Prompt to take advantage of it.

To get started we’ll need to use the CMD prompt. Alternatly, you can “Run” a command from the “Start Button” this will work too.

Let’s start with the CMD prompt:

For Windows XP click Start/Run/CMD

For Windows 7 click Start/All Programs/Accessories/Command Prompt

This will open a Command Console allowing you to type in the following command:

cleanmgr.exe /sageset:99

Running CleanMgr from the Command Prompt

This will bring up a new Disk Cleanup Settings window

On Windows XP computers, you should usually select the following categories: Temporary Setup Files, Downloaded Program FIles, Temporary Internet Files, Microsoft Error Reporting Temporary Files, Old Chkdsk files, Recycle Bin, Temporary Remote Desktop files, Temporary Files, WebClient/Publisher Temporary Files, Catalog files for the Content Indexer. Optionally you could select Debug Dump Files and Offline Webpages as well. You should almost NEVER select Office Setup Files.

On Windows 7 computers, you should usually select the following categories: Temporary Setup Files, Downloaded Program Files, Temporary Internet Files, Debug Dump Files, Old Chkdsk files, Recycle Bin, Service Pack Backup Files, System error memory dump files, System error minidump files, Temporary Files, Temporary Windows installation files, Thumbnails, Files discarded by Windows upgrade, Per user archived Windows Error Reporting Files, System archived Windows Error Reporting Files

Once you have made your selections, Click OK.

Now that you have saved your settings, run the following command:

cleanmgr.exe /sagerun:99

This process could take some time to complete and will run on all attached drives. So if you have network drives or external drives you do not want included, be sure to disconnect or remove these drives.

Interestingly enough the laptops were connected to the internet with Verizon 4G modems. They were able to download files, surf the internet, and do pretty much everything else as normal. No settings on the laptop, Outlook 2010, or the Exchange server had changed from one day to the next.

We ruled out the Exchange server by sending from Outlook Web Access as the user. We ruled out the user SMTP account by sending from a stand-alone desktop machine as the user. We then ruled out the laptops themselves by connecting them to a hard wired LAN connection and sending from Outlook 2010 without any problem. The only time we experienced the 550 5.7.1 error was when connected using Verizon 3G or 4G.

Could these recent problems with the Verizon network have something to do with it? We updated the VZAccess Manager software to the absolute latest version (Help / Check for Updates). During that process the firmware of the device was updated as well.

Surprisingly, after the Verizon software and modem updates it was possible to send email again. Hopefully this helps anyone else who is having trouble sending email through SMTP while connected to a Verizon 3G or 4G modem. Upgrade your modem!

Here are a few pictures of the inside of a case that recently came into our workshop.

Over time, dust accumulates inside your computer case

Over time, dust can cause internals components to overheat, due to lack of air circulation

Dust is a slow computer killer. Dust prevents normal air circulation through the computer case. The case draws cooler air from outside the case through the various airflow openings of the case. The lack of circulation caused by dust will often result in internal component overheating and failure. These include video cards, hard drives, computer processor and other internal hardware.

Common intake openings of the case include the front and the sides of the case, while exit openings include fans usually mounted in the rear of the case and the power supply.

Keeping these openings clear of debris can help to maintain the proper airflow around the case. A good practice is to also maintain four to six inches of clearance from the computer to any object which could block airflow.

In conclusion, dusting out your case every month can help to extend the life of your computer – instead of it suffering the fate of death by dust.

There are many options available if you are looking to dispose of an old hard drive. Some professional destruction methods include:

• Shredding it using a local shredding company
• Taking it to a computer recycling company
• Mailing it to a hard drive destruction specialist
• Bringing it in to a local computer shop that will dispose of it

These methods are ideal, but they usually cost money. Professional destruction of a hard drive could cost $70 or more in some areas! So what is a low cost method to dispose of the hard drive and keep your personal data safe if you are low on funds? Considering you have all the right tools, this method won’t cost you a dime and is a very secure way to get rid of a hard drive while keeping your data secure.

Step 1: Wipe it! Wiping a hard drive in essence destroys the data by writing over it with random characters. There are many free utilities to help, a good one is Active@ KillDisk. You can download the free utility from their website, click: Active@ KillDisk. This free software overwrites all of the data on your old hard drive with random characters and WILL DESTROY ALL OF YOUR DATA! Be sure you have performed a complete backup and have transferred the data from your old hard drive to your new system before wiping it.

Step 2: Remove it! Physically remove the hard drive from the system. This is usually the easy part, you’ll just need a screwdriver and a little patience. Keep in mind that you will still be able to sell or donate the old computer without a hard drive missing, just be sure to let the new owners know in advance that they will need a new hard drive and operating system.

Step 3: Drill it! If you plan on using the old hard drive again, skip this step. Otherwise it’s best to physically destroy the old hard drive just to be 100% certain that the old data is completely destroyed. This step is not only fun, depending on how much personal data you had on the old drive it can also help you sleep better at night.

Wearing protective goggles, gloves, and a dust mask for your mouth and nose take a drill and a metal drill bit to the drive. You’ll want to drill through the drive completely from one side to the other, and you’ll want to do this multiple times. Two important areas for you to drill through are the platters and the controller board. See examples in the below images.

All done!

Here’s the system in question, innocent enough looking right?

This is the battery compartment. It’s hard to see in the picture, but there is only a small, thin strip of plastic between the top of the battery compartment and the internal workings of the buttons on the other side (see next image).

This is the other side of that compartment. Notice the volume up/down buttons and other system buttons in this area?

Long story short, if there is any debris in the battery compartment area or the battery is situated evenly slightly incorrect the volume up/down buttons can get locked into a state of constant pressing. This system, upon boot, was stuck in an audio up/down keystroke event that made it hard to type and produced a horrible buzzing noise in the operating system. We fixed this issue in our computer repair office here in Phoenix.

> There is no available CAT5 cable leading to a modem or router
> The only internet connection nearby is on an established router that you can’t change settings on
> Wireless access is available in the building

One option is a cradelpoint 4G router, using a Verizon 4G modem to setup internet access for multiple computers. However, in this case, we need a solution that is not limited by the amount of data you can download before overages set in. We settled on using a spare Linksys WRT54G router. When flashing this to DD-WRT, it’s possible to set the WAN on the wireless router to client mode and connect to an existing Wi-Fi network. We could then create a LAN on the device and plug-in computers to create our own network that would use the connected Wi-Fi network signal to pull internet!

Take a look at this article “Building a Wireless Bridge” that is helpful for this type of configuration. How can our Phoenix computer repair office help you solve your office networking challenges?

It’s always fun working on these tiny systems! With the small size heat is definitely a big problem – make sure you get your computers checked out on a regular basis. Dusting out the inside of your computer systems is a big help to preventing fan (and possible motherboard or cpu) failure.
