I found a fix from someone who had a similar problem but you need to load windows to apply it.
In Dev Man > System Devices > VIA CPU to AGP2.0/AGP3.0 controller and one of the two drivers would be something like UAGP1.sys
Aparently gagp30kx.sys is a Windows driver and it's better besides, anyway it's what windows wanted in the first place! (ie. causing the crashs)
Anyway, click on update driver and in the window that appears, if you are asked to connect to Windows Update to search for new drivers, choose "No, not this time".
When asked to install the software automatically or from a specific location, choose "Install from a list or specific location (Advanced)". You will then be asked where you would like to search (CD-ROM, Floppy Disk, etc.), choose "Don't search. I will choose the driver to install" and then click Next.
You should now see a window asking you which driver to install, show compatible hardware should NOT be checked. Scroll down in the right pane to "VIA CPU to AGP Controller", you should find that there are two copies of it with (Windows) next to it, you want to choose the first one you find (the top one, not the second). Make sure that it wasn't "VIA CPU to AGP2.0/AGP3.0 Controller" you chose, as this is the normal Hyperion driver (btw, it'll dissapear from Dev Man later).
Windows then will give you a message about the possibility of the driver not being compatible with your hardware, and asks you whether you would like to install it anyway or abort, choose install.
The original VIA CPU to AGP2.0/AGP3.0 Controller has dissapeard!
In Dev Man > system devices> VIA CPU to AGP Controller > Driver Details should have 2 files:
pci.sys and gagp30kx.sys
