Dell Dimension 5000 black screen with blinking cursor

I have an old Dell Dimension 5000 PC and I hadn't used it for a while. I'd had the Windows 8 preview (yes Windows 8 can run on a really old Pentium 4!!!) on it but now I was thinking to install something else. When I switched it on all I saw on the screen was a black screen and a white cursor blinking in the top left. No BIOS messages at all.

I opened it up and looked at the four memory slots. They are in pairs, two black and two cream. I had both filled, two original 512MB cards and two 1GB cards. I had a gut feeling the original 512MB cards were unhappy so I removed them. I switched on and hey presto my old Dell came to life!!!

Now my old PC is running with just 2GB of RAM and not 3GB but it doesn't matter. I'll be installing Crunchbang Linux or similar anyway.

Word 2010 printing is very slow

When printing from Word 2010 I found that it would say "connecting to printer" for ages... I was only printing one page of text!

Solution 1 (maybe)
On one website it said to turn off the background printing, I tried this but it didn't help me. Maybe it'll work for you, here's what to do:
Click File | Options | Advanced
Scroll down to the Print section
Turn off Print in Background (see the screen shot opposite)
Click OK


Solution 2
I downloaded the latest driver for my printer and installed it. I restarted my computer and now Word is printing normally again. Sometimes the simplest solutions are the best!

Crunchbang Linux

Crunchbang Linux is an operating system you can download for free from http://crunchbang.org/. It can run on low specification computers. I found it recently and I've been trying it out on a couple of computers I have. In this article I'll go through installation and what is included, with my first impressions.

Crunchbang is based on Debian which is the same base as Ubuntu uses, this means there are lots of software apps ready to be installed on Crunchbang. It uses the Openbox user interface which is minimalistic. If you like clutter, Crunchbang is not for you. The sleek Openbox interface means Crunchbang is simple and easy to use. Also, it's good for small screens because it doesn't take up much screen space with fancy graphics.


Asus Eee PC
Back in 2008 I bought an Asus Eee PC 700 4G with 1GB RAM (upgraded!). This was the original Eee PC, one of the first NetBooks. It was relatively cheap and excellent for casual web surfing. It was from the days before tablets were widespread!

The Eee PC came with a simple Linux operating system that was fine to start with. Later I moved on to EasyPeasy. An operating system based on Ubuntu. Here's an article I wrote about it:
http://mgxp.blogspot.com/2010/07/easypeasy-netbook-os.html
However, it was big and heavy, it kept updating and then would no longer update because my 4GB SDD main storage was almost full.

Some time ago I looked at a number of Linux operating systems but I didn't find anything that worked well on my Eee PC with its meagre disk space (4GB). Even some systems that say they work with Eee PCs actually only work with the later 900 model. I have the 700...


Installing Crunchbang on the Eee PC
Go to http://crunchbang.org/download/ 
Download the 32-bit ISO, it is less than 800MB in size.
Use Win32diskimager to write the ISO to a USB flash drive - I used a 1GB flash drive.

Plug the USB flash drive into the Eee PC.

To boot the Eee PC from the USB flash drive, press Esc as soon as you switch on the Eee PC.

At the Crunchbang menu, select the Text based installation, the Graphical option didn't work on my Eee Pc. I found the text based installation straightforward, it is menu driven so it's still easy. You have to select the language, location, keyboard layout, it'll ask you to partition the hard disk, select the default and it'll set up everything for you.

WARNING! Anything you already have on the computer will be deleted forever.

Once it had finished installing you will be prompted to run a 'post installation script'. Before you do that, connect to the internet. Click the wireless icon in the top right and select your WiFi hotspot. Now start the post installation script. It will install updates and additional software apps that you may need such as LibreOffice (a free office suite). In my case because I wanted to keep the Eee PC's little 4GB disk as free as possible, I didn't install much (just press S to skip each time).

Once it has finished everything is working! Yes everything. The network drivers, graphics drivers, everything is installed. A completely painless installation.


Using Crunchbang on the Eee PC
It is excellent, fast and slick - yes even on the little Atom processor of the Eee PC. The best news is that it fits on the small screen. Here's what Crunchbang looks like:



Crunchbang on the Eee PC


On the top you have two virtual desktops and you see your loaded programs listed. 

On the right you can see System Info and Shortcut Keys. The Shortcut Keys are useful but what does it mean by "Super"? The Super key means the Windows key on a Windows PC. 

You can right click on the desktop to bring up a menu, this is shown in the following screen shot:


Crunchbang and Dropbox on the Eee PC


In the above you can see I'm about to start Dropbox. This Dropbox app is included as standard with Crunchbang and it works perfectly.


Crunchbang on the Eee PC


In the above I've opened the web browser and I'm on the BBC News website. As you can see it doesn't quite fit on the small Eee PC screen. But it's usable, it's possible to press Ctrl- to reduce the size of the web page. You can also scroll of course. I can also press F11 to go full screen of course, that gives me a little extra space.

The browser that is included is called Iceweasel. It's a Mozilla based browser so it works like Firefox. If you wish you can install Chrome or Opera - there are menu options to do this. Right click the desktop, click Network | WWW Browsers.


Install Crunchbang on the IBM Thinkpad T42
The T42 is a classic. It's rugged and I have one that still works after many years of use. The battery is dead though, so it's tethered. Still it could be useful for a PC to surf on. The RAM is just 512MB and the processor is an Intel Centrino. There's a 40GB hard disk drive, at least a little more space to play with than with my Eee PC.

I used the same USB flash drive that I'd prepared for the Eee PC.

Plug the USB flash drive into the T42.

Switch it on and press the blue Access IBM button

Press F1 for the Setup

Select Config | Floppy Drives

Legacy Floppy Drives [Enabled]
Press Enter and select [Disabled], you should see the following:
Legacy Floppy Drives [Disabled]
(this is important, if you don't do this then the installation will stop part way through)

Press F10 to save and exit the Setup program

The T42 will boot to the Crashbang menu. You can select the graphical or text installations, both work fine. The rest is just as it was with the Eee PC described above. The installation was smooth, not too many questions. Once it's finished connect to your WiFi hotspot before running the post-installation script. On my T42 I installed LibreOffice and other software because there's plenty of space free.


Using Crunchbang on the T42
It's a pleasure to use! The screen is nice and big, the old 4:3 ratio too. Even though the T42 only has 512MB RAM I've not felt it. It runs very nicely.



Conclusion
I've not been using Crunchbang for long but my first impressions are that it is excellent. It's a perfectly small, neat, tidy and slick operating system. It can breath life back into those old computers you have lying around the house. Certainly if you have an Eee PC I would highly recommend Crunchbang because it fits the screen and doesn't have many dialogue boxes that are too big for it.

Also I found the forum on the Crunchbang site to be useful. People are posting real solutions there.

Reset your Windows password

Introduction
Are you suffering from amnesia? Or maybe someone you know? They can't remember their Windows password and therefore cannot access their computer. What to do? You could reinstall Windows but I'm sure you'd prefer a less painful alternative.

There are several free solutions, search for "Windows Password Reset" or similar and you'll find many.  Most are Linux boot disks with utilities specifically for resetting a Windows password. The first I tried was PC Login Now. It was easy to use but unfortunately it didn't work on the Windows XP computer I was using for my test. I tried several of its options including 'Empty password' but it did nothing.

The next I tried worked very well, it's called: 'Offline Windows Password & Registry Editor, Bootdisk / CD' and this worked very well.

Offline Windows Password & Registry Editor
It is very small, just a 4MB download. According to the blurb it supports Windows NT, 2000, XP,Vista, 7 and server editions. There's no mention of Windows 8 yet.

It has a text based interface. This might turn some of you off and it might turn a few of you on! Personally I like this text based approach because it doesn't require anything fancy (graphics drivers) to run it and it's fast to start up. I decided to download it and try it on a Windows XP computer.



Download
Browse to: http://pogostick.net/~pnh/ntpasswd/bootdisk.html

There is an ISO version to burn to a CD or you install it to a USB flash drive - this is an easy option as the software required to do this is included in the download zip file.

Download 'Files for USB install', at the time of writing this (March 2013) there was a file called usb110511.zip


Install to a USB Flash Drive
Of course there are instructions on the Offline Windows Password & Registry Editor website:
http://pogostick.net/~pnh/ntpasswd/bootdisk.html
...but in any case I've written the steps I took here:

You'll need a USB flash drive, any capacity will work, even an old 512MB one for example.

Plug in the USB flash drive.

Make a note of what drive letter the USB flash drive has, perhaps, E:, F:, G:, etc.

In Windows Explorer check that you can access and use the USB flash drive. If there are any files on it you want to keep, copy them somewhere else.

Format the USB flash drive (FAT16 is fine). You can format the USB flash drive by right clicking on it and selecting Format.

Extract the files from the usbXXXXXX.zip file to the USB flash drive.

Open a command window (CMD) - in Windows XP click Start | Run, type CMD [Enter], in Windows 7 click Start and type CMD [Enter] in the search box.

At the C:\> prompt type X: [Enter]
(where X: is the drive letter of your USB flash drive)

Type   SYSLINUX -ma X:  [Enter]

The above command is important, it writes the Linux boot sector to the USB flash drive. Once you've done that, the USB flash drive is ready to be used.


Reset a Windows Password
Take the USB flash drive and plug it into the computer with the Windows password you want to reset.

Restart the computer

On the startup screen you must boot from the USB flash drive. Different computers have different ways of doing this, for example, press F12 if it is a Lenovo computer.

There is a series of on screen menus. You should stop and read each one carefully but in most cases the default option (press Enter) is fine.

I was going to detail the steps I took but there's no need, there is a very good 'walkthrough' already here:
http://pogostick.net/~pnh/ntpasswd/walkthrough.html


Conclusion
'Offline Windows Password & Registry Editor' worked well for me. It was fast to download, install to a USB flash drive and to actually reset the password. It isn't pretty though, the black and white text interface with old fashioned text menus might put some off. Above everything the fact is that this utility works. It should be a part of every IT professional's toolkit.

ASCII Text to Hex Converter

I found a very good/simple online ASCII text to Hex converter. It will also do the reverse and turn Hex into ASCII text. Here it is:
http://www.dolcevie.com/js/converter.html

If you don't know what hex is, here's the Wikipedia page to explain all :-)
http://en.wikipedia.org/wiki/Hexadecimal



Update July 2014
The above link doesn't work any longer :-(
Here's another web page that does the same and more:
