R232275 are motherboard chipset drivers. R293649 is a BIOS update. R248560 are your onboard sound drivers. What did you do - download the top few items in the list? None of these are graphics (video) drivers.
The drivers should be harmless. The BIOS update has a very small, but not zero, chance that it will render the laptop unbootable.

I see 9 "video" drivers for Win7 X64. There are NVidia and AMD drivers, so you'd have to know which graphics adapter (aka video card) is in your system. If you look up the device hardware ID for the adapter in Device Manager, you can try plugging that into a web search engine. For example: if I search on:
PCI\VEN_10DE&DEV_0638&CC_0300
I find that I have a Quadro FX 1800, which is correct.
Best of luck.
