Okay...I have had this problem for awhile now and finally figured it out. First off my system
P3 450
Tyan 1854 MB
128 RAM
V770 Ultra
The Solution for me was to down load the AGP drivers for the VIA chip system on the mother board. Fixed everything. Hopes this helps
Socket 7 Motherboard AGP Video Card Installation Guide:
1. Windows95 OSR2.1, Windows98, NT4 w/ Service Pack 3 (or SP3 +SP4)
2. All motherboard patches installed:

There are also some motherboard bios options that you need to change to keep the AGP socket running at 66mhz. Please keep in mind that all AGP 1x,2x,4x AGP cards run a 66mhz bus speed, it is the texture transfer rate that the 1x,2x,4x refers to. The first thing to look for an option of AGP 2x or AGP Turbo and DISABLE it. After that, if you have a VIA MVP3 chipset, reinstall the AGP driver in NORMAL mode. If you have a ALI chipset motherboard, you also need to DISABLE the following bios options: Primary Frame Buffer, VGA Frame Buffer.
Lastly in the bios, make sure the option "assign IRQ to VGA" is enabled for the Viper cards. For the Stealth or Monster Fusion cards you can leave this option on Disabled.
3. Microsoft(r) Windows(r) 95 Update for AMD-K6(r)-2/350 and Above--http://www.amd.com/products/cpg/k623d/win95_update_k6.html
4. Latest motherboard bios update
5. Latest Video card driver--http://www.diamondmm.com/products/drivers/driver-index.html
For AGP to work with Windows95, here is some basics for any AGP card (socket7 and PentiumII):
1. Windows 95 version OSR2 (950b or 950c)
2. USB update to upgrade to OSR2.1 (on the windows95 cdrom that says "With USB support" on the front in the X:\Updates\Other\USB\USBSUPP.EXE or from this Diamond site--ftp://ftp.diamondmm.de/hotline/files/usbsup.exe) To check for the OSR2.1, START>RUN>"qfecheck". The windows version should be 4.10.01.1212b or 4.10.01.1212c
3. Chipset patch for the motherboard installed-ie LX, BX, VIA MVP3, ALI V (if not loaded, in Device Manager will show up under Other Devices as PCI BRIDGE)
