Video displays only 640x480 resolution in 16 or 256 colors

Please help!

My Compaq Presario 4814 will only display a monitor resolution of 640x480 at 16 or 256 colors.

History:
I purchased the computer used from a friend. Little did I know that all the documentation and software had been lost (thrown out by a disgruntled room mate). Because a peripheral device that I wanted to connect needed Windows 98, I upgraded from Windows 95 to 98. The system would run fine for a time (less than an hour) and then would slow to a crawl and finally lock up. Re-booting was the only way to get back running, but then it would slow down again. After various efforts at fixing the problem, something got corrupted and the computer would only come up in safe mode. I had no rescue CD from Compaq and could not get the system working. I called Compaq for help. For a $30 fee for the technical support, they sold me a $10 rescue CD that would "bring my computer back to the factory setup". When I run the rescue CD, the system comes up, but only at a screen resolution of 640x480 and 16 or 256 colors. Compaq wants another $30 to fix this problem, or get me on to the next problem that needs fixing.

Any ideas??????

System info:
Pentium 233 MHz processor
S3 video chipset (haven't seen this, but Compaq insists this is what I have)
Permedia 2D board (monitor connects through this, what does this do??)
Windows 95

Compaq info indicates a 2 MByte display adapter... Right Click a blank part of your Windows desktop, Properties, Settings, Advanced button, Adapter. What does it say is installed? Notice the Change button? Larry

Bah! Right Click a blank part of your Windows desktop, Properties, Settings, Advanced button, Adapter, Change, Specify Location…, and try detect. If that doesn’t work, try Display a List of all drivers…, S3, Trio64V or whatever will work with the adapter. The idea is to use the stock Windows driver. Larry

Had tried various drivers, and the sservice pack that S3 has (SP6525), but nothing worked until last night. Removed the Permedia board. Then the computer accepted the S3 drivers and all is happy. Since then, I finally found the Permedia drivers online and will try reinstalling the card and software.
