There are many cheap video cards on the market but the cost you often pay is that you will have a darker or duller display with less detail. It's not worth the small saving.   myxlfidian (150)

Improve the speed of virtual machines:
  • Increase the amount of RAM you have on your computer. If you are able to make a lot of RAM available to the virtual machine, you can turn off its disk cache, providing even further speed improvements.
  • Multiple CPU cores will help.
  • Storing your virtual machine files on a separate hard drive to your main hard drive will help.
  • Keep your drives defragmented.
  • Hardware Assisted Virtualization helps. You may have to enable it in BIOS as well as turn it on in software.
  • The faster the hard drive the better

If your video is still too dark, it's due to the age of your monitor. Older monitors get darker.   myxlfidian (150)

Sound cards: Onboard sound is definitely inferior to a PCI Sound Card. It also means more processing work is done off the motherboard.   myxlfidian (150)

Uninterruptible power supply (UPS) is a battery backup unit which can supply power to your computer for a period of time when your mains power is unavailable. The battery power kicks-in the instant the mains power fails, and gives you a chance to save your work or finish-up whatever it is you are doing. These units are now cheap enough for the home computer user.   Kevin Solway (173)

Making a bootable DVDROM:

  • Choose an ISO file suitable for your computer. This file contains the operating system. It is either for: PowerPC (Mac), or 32bit (x86, pre-2004), or for 62bit (x86_64, new computers).

  • Choose a burning program that can burn ISO images. Follow steps like these:

    - Erase the DVDROM disk you wish to burn the file to, or see that it is empty.

    - In Nero 8, choose: Burning ROM, DVDROM(boot). Settings: Image file, no emulation, loaded sectors: 4, no relaxation of restrictions. Select 'New (compilation)'. In the main menu, select: Disc / Set ISO labels (e.g. 'OPENSUSE11X86_64'). Then: Recorder/Burn image.

    - In CDBurnerXP v4, choose: Burn ISO image. Settings: Select ISO image, Disk at Once, Write speed: 4x (5540KBps).

  • Test the DVD works. First enter the BIOS/setup to change the boot sequence to begin with CD/DVD. To enter BIOS, press your computer's BIOS key before the POST (e.g. F2).   kellyjones00 (593)

    Headphones: Some brands like Sennheiser make a range of models with detachable cables. Each ear has a cable with a 3.5mm jack that plugs right into the ear. If the headphone fails in one ear, its almost always the cable, which costs less than a third of the price of a new set of headphones. Cables are the most common failure point of headphones but over 95% of headphones do not make them as detachable, replaceable genuine accessories.   myxlfidian (150)
