You are 1000% sure you have an Intel HD 3000 OR 2000 right? If you get me your hardware ID's I'll add them to a customized graphics driver.
You can find them by going to the device manager, right clicking your graphics card, then properties, then details, then on the dropbox choose Hardware Ids. Just copy and paste them here.
It's Intel X3100, but I'm not actually 100% sure it's part of the HD 3000 series. I just assumess this because of the numbers so maybe I am wrong.
If it is part of the series, here is the Hardware ID's:
PCI\VEN_8086&DEV_2A03&SUBSYS_3C1817AA&REV_03
PCI\VEN_8086&DEV_2A03&SUBSYS_3C1817AA
PCI\VEN_8086&DEV_2A03&CC_038000
PCI\VEN_8086&DEV_2A03&CC_0380
If it is not part of the series then what can I do, if anything, to get a proper driver?
EDIT:
I tried your Series 4 driver (including the certificates of course) and this one I could install after right-clicking a .inf file but it still didn't work after a reboot.
Also couldn't run Setup.exe because of the same message I gave earlier..
