Prepare hardware for a Windows reinstall

Sometimes the only way to rid your PC of rogue software and other maladies is to revamp your Windows installation. Follow these four tips to keep your hardware on good terms with your reinvigorated Windows setup.

Get your discs in a row: Before you begin, gather the CDs containing the device drivers Windows will require to run your computer, printer, and other hardware. Almost every component in or connected to your PC needs to have its own device-driver program installed in Windows. This includes printers, graphics cards, network adapters, and even individual chips on your system's motherboard.

All of the drivers your PC needs may or may not be included on the Windows CD (or on the restoration disc) that came with your system. After recently reinstalling Windows XP on my Dell Dimension, I found that the machine's OS CD failed to install my network drivers and other key hardware drivers, which meant that initially I had no Internet access. Since I had lost the disc holding my network card's driver, I had to use another PC to connect to the Web and download the necessary program from the maker's site. Many drivers--such as those for equipment you bought separately--may have to be installed from their own discs, so keep all of your software CDs handy.

If you're reinstalling Windows from a standard Microsoft Windows CD rather than from the disc that shipped with your PC, don't assume that the generic Windows CD will have all of your system's current drivers. Visit the support sections at the Web sites of your PC and peripheral manufacturers, download up-to-date drivers, and save them on removable media (the reinstallation will likely wipe these updates off your hard drive).

Avoid hardware activation: Every time you reinstall Windows XP, you have to phone home to Microsoft to reactivate the OS. Avoid this annoyance by copying the existing hardware signature file that Windows creates from your computer's configuration and pasting it back into the freshly installed version of Windows XP.

Open the C:\Windows\System32 folder in Explorer and copy the files 'wpa.dbl' and 'wpa.bak' to a floppy disk, CD, or other removable medium. At the end of the XP reinstallation, choose not to reactivate Windows. When the reinstallation finishes, reboot your PC in Safe Mode by pressing F8 before Windows launches. Once Windows has opened in Safe Mode, copy the two files over the new versions in the C:\Windows\System32 folder.

Note: This works only on the PC where the 'wpa.dbl' file was originally created; it won't bypass Windows XP activation on other computers. And if you made significant hardware changes to your PC before reinstalling Windows XP, you'll probably have to reactivate the OS anyway.

Do a driver check: Finally, check Device Manager to confirm that all of your drivers were installed. In XP and 2000, right-click My Computer, click Manage, and select Device Manager on the left of the screen. In 98 and Me, right-click My Computer, select Properties, and click Device Manager. Any entry marked with an exclamation point (!) in a yellow circle (or a white question mark in a green circle in Windows Me) has a problem; if you're lucky, a new driver will fix it.

It really doesn’t get more “gaming laptop” than this.

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
