Another problem that seems to come up quite often is installing more than 512Mb of ram on Windows 95, 98, or ME.  Basically, if you want to install more than 512Mb of ram in your computer, for example 1Gb of memory, then you really should be using Windows XP.  This is due to the fact that Windows 95 and 98 don't officially support more than 512Mb of ram and you may get errors happening when you use large amounts of ram.  For example, I noticed that with 1Gb of ram in Windows ME, you cannot install certain graphics card drivers.

However, if you really do want to use more than 512Mb of ram in earlier versions of windows, then it is possible to do so, by editing your system.ini file.  To do this, please do the following;

1. Click "start", then click "run".
2. In the box, type in the following without the quotation marks, "C:\windows\system.ini notepad"
3. Scroll down until you get to the [VCache] section.
4. If the line "MaxFileCache = " already exists, then change it to read "MaxFileCache=524288" (without the quotation marks).

If however the line doesn't already exist, then simply add it directly underneath the [VCache] section.
