Install At Least 2GB Computer RAM

With Windows 7 and Hoster 4.xx with 10,000+ songs in your Songs Database, your computer needs at least 2GB RAM to run safely and reliably. With insufficient RAM, you may be importing disc 670 and weird bad things start happening... for no apparent reason... out of RAM!

Processor Speed Should Be At Least 1.3GHz

Hoster 4.x requires at least 1.3GHz to safely run all the new features. If you have a tightly designed Laptop or Shuttle computer, you may not be able to buy and install a faster processor as the Power Supply may be insufficient for an upgrade. However... adding a faster processor MAY or MAY NOT require more power. If you don't know, you need to find technical help to do this for you. >With parts and labor, it may be cheaper to replace the computer.

Hard Drive Free Space

Most users don't know that Windows REQUIRES free hard drive space to perform "housekeeping" tasks to run reliably. Some experts say you need 25% free hard drive space, but at least 10% would be a minimum. If you have a 100GB drive, you need at least 10-25GB free. With a 250GB drive, you need 25-60GB free. If you see your hard drive light flashing a lot after 5 seconds when a new song starts playing, your drive may be "thrashing" due to not having enough free space. If you see this, add another USB external 1 Terabyte hard drive and copy your karaoke, audio, and videos files to it so your C: drive has more free space.
