How can I detect my graphics card with no driver installed? [duplicate]

Solution 1:

For Windows I would see if Slimdrivers can autodetect it first otherwise try this.

Device Manger->Display Adapter
Right click on the device and click properties.
Click on the details tab.
Use the drop down to select:"Hardware Ids"
Ven is short for vendor so ATI/AMD, nvidia, Intel are the most common.
Dev is the device ID.

google Dev #### and Ven ####
You should be able to find it.
