Driver Updates

Hey there..

I scanned my drivers with the free-scan-utility that is provided in driveragend.com and found out that some of them where out-of-date.
Instead of becoming a member I decided to try and install the out-of-date drivers manually. I copy-pasted the names of the "bad" drivers and the outcome was some kind of a list..

for example "Intel(R) 82801EB Ultra ATA Storage Controllers"

results: infinst_autol_8_0_1_1002.exe
intel_infinst_enu_6_3_0_1007.exe
nb_drivern211intelchipset.zip
infinst_autol_7_2_2_1006.exe
.....etc (up to 2 pages)

My question is: How do I know which one is the right one for me?

Thnx in advance..
