1. First, run a scandisk or checkdisk. Let Windows fix any errors.

2. Run a disk cleanup utility…this will flush your temporary internet folder, trash can, temp system files, etc.

3. Delete any garbage files or data…if possible, run a Duplicate File Finder program.

4. Run Defrag on all partitions (NOTE: run this after you have deleted all trash and excess files!)

5. Run a registry cleaner utility and delete or get rid of any orphaned entries in that registry.

6. Check your exisiting swap file for it’s size and location (*will explain location later in the post). If you have alot of ram (i.e. 1 gig and over) set this swap file to something small, like 250 mb. The reason is that this will force Windows to load more into memory, resulting in faster performance (note: some games and applications actually require a certain sized swap file so check your applications performance after making a size adjustment for any error messages.)

Ever wondered just what that enigmatic name means?

Gaming and multimedia applications are some of the most satisfying programs you can get for your PC, but getting them to run properly isn’t always as easy as it could be. First, the PC architecture was never designed as a gaming platform. Second, the wide-ranging nature of the PC means that one person’s machine can be different from another. While games consoles all contain the same hardware, PCs don’t: the massive range of difference can make gaming a headache.

To alleviate as much of the pain as possible, Microsoft needed to introduce a common standard which all games and multimedia applications could follow – a common interface between the OS and whatever hardware is installed in the PC, if you like. This common interface is DirectX, something which can be the source of much confusion.

DirectX is an interface designed to make certain programming tasks much easier, for both the game developer and the rest of us who just want to sit down and play the latest blockbuster. Before we can explain what DirectX is and how it works though, we need a little history lesson. (more…)

Since defragging the disk won’t do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance the performance and reliability of your customers’ PCs. Best of all, most of them will cost you nothing.

1. To decrease a system’s boot time and increase system performance, use the money you save by not buying defragmentation software — the built-in Windows defragmenter works just fine — and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.
2. If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.
3. Ensure that Windows XP is utilizing the NTFS file system. If you’re not sure, here’s how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it’s important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives. (more…)

Fatal error: the system has become unstable or is busy,” it says. “Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications.”

You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?

1. Hardware conflict

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.

For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.

If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow ‘!’ appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.

Sometimes a device might share an IRQ with something described as ‘IRQ holder for PCI steering’. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it. (more…)

Microsoft offers $250,000 reward for Conficker arrest and conviction.

REDMOND, Wash. – Feb. 12, 2009 - Today, Microsoft Corp. announced a partnership with technology industry leaders and academia to implement a coordinated, global response to the Conficker (aka Downadup) worm. Together with security researchers, Internet Corporation for Assigned Names and Numbers (ICANN) and operators within the Domain Name System, Microsoft coordinated a response designed to disable domains targeted by Conficker. Microsoft also announced a $250,000 reward for information that results in the arrest and conviction of those responsible for illegally launching the Conficker malicious code on the Internet.

“As part of Microsoft’s ongoing security efforts, we constantly look for ways to use a diverse set of tools and develop methodologies to protect our customers,” said George Stathakopoulos, general manager of the Trustworthy Computing Group at Microsoft. “By combining our expertise with that of the broader community we can expand the boundaries of defense to better protect people worldwide.”

As cyberthreats have rapidly evolved, a greater level of industry coordination and new tactics for communication and threat mitigation are required. To optimize the multiple initiatives being employed across the security industry and within academia, Microsoft helped unify these broad efforts to implement a community-based defense to disrupt the spread of Conficker.

The Conficker worm is back with a vengeance, infecting over one million systems in the past 24 hours. The refined version of this malware scans networks for weakly protected machines and actively attempts to spread itself via USB thumb drives. Neither feature was present in the original version, and so far, the attack is working.

It has been over a month since we heard much about Conficker, but the worm has reappeared with a vengeance over the past seven days. According to Finnish security company F-Secure, more than one million PCs have been infected with the worm (also known as Kido or Downadup) in the past 24 hours, with a total of 3.52 million machines infected worldwide. According to F-Secure, that 3.52 million is a conservative estimate.

The problem isn’t so much with the older version of Conficker (now known as Conficker.A) but with a new flavor, dubbed Conficker.B. Ars spoke with Roger Halbheer, Chief Security Advisor of Microsoft’s EMEA (Europe, Middle East, and Africa); he’s been monitoring (and writing) about the current spread of infections. The skyrocketing infection rate is actually being caused by several factors; Roger describes Conficker.B as a “beast,” and Microsoft has built the following diagram to demonstrate how the worm functions.
