Windows XP black screen on bootup with only mouse working

Problems:
– Can’t load Windows XP GUI, all I get is my mouse on a black screen.
– Can’t load “Safe mode with command prompt”
– Can’t do a repair install or use the repair console to fix the problem.

What happened:
It wasn’t my computer and I wasn’t there when it broke down, but apparently someone was playing World of Warcraft and they got a message box (probably outside of the game) asking them a question, to which they responded “yes” (or whatever positive answer there was) which led to a blue screen and wouldn’t allow the PC to boot into windows. There was an error message that said something roughly like “cannot load windows”. I got an explanation of what went wrong from people who don’t know much about computers so it’s hard to explain in detail. They did a repair install without me and that led to the problem this post is based on.

Solution:
– Backup data using another PC and format.

Important Tip:
– When you have a catastrophic failure, don’t do a repair install of windows until you’ve tried the recovery console via “Safe Mode with Command Prompt”. Repair installs sometimes won’t work! When you do a repair install, it immediately deletes all restore points so you have no hope but to reformat if the repair install doesn’t work.

Windows XP Resuming Setup Loop

The problem: I have a computer that died from what I think is a virus, but after doing a repair install, it just starts up the XP setup every time it boots instead of windows. It crashes somewhere during the “installing devices” part.

The solution: I booted from the CD and started the repair install again from scratch and it stopped the loop.

The reason: The repair install was started at someone else’s house, with different equipment connected

Shorter nested IF statements in Excel

This code checks to see if A1 equals the letters K, H or L.

Instead of using:
[code lang=”html”]=IF(A1=”K”,TRUE,IF(A1=”H”,TRUE,IF(A1=”L”,TRUE,FALSE)))[/code]

You can use:
[code lang=”html”]=IF(OR(A1=”K”,A1=”H”,A1=”L”),TRUE,FALSE)[/code]

As you can see, it’s a lot shorter and makes a lot more sense. Especially if you need to add more to it in the future.

Easy stylesheets with basic PHP

Create a file called stylesheet.php and link to it in you’re page. Then play with this code:

[code lang=”php”] < ?php header('Content-type: text/css'); // Colour scheme $primary = "#44749d"; $secondary = "#c6d4e1"; $tertiary = "#ffffff"; $quaternary = "#ebe7e0"; $quinary = "#bdb8ad"; ?>

BODY {
background: < ?php echo $tertiary ?>;
color: #000000;
margin: 0px;
}
[/code]
