Acer 5100 x86 only basic drivers available

I recently reformatted this little 5100 I had because it was totally bogged down. I had upgraded it previously to Windows 7. This time I did a clean Windows 7 install, so I got none of the Acer bloat that usually comes with the laptop. That saidthe install went well, but I have always been baffled about reinstalling drivers properly. I had used Double Driver to back up the previous drivers and most of them reinstalled without issue. A couple of them were digitally un-signed so they didn't install. Now I went to the Acer site for drivers and the 5100 x32 is about Vista which I assume they are also for Windows 7 upgrades, however there are no chipset drivers or motherboard. All I can see are the very basic. How do I re-install drivers after a re-format? Some say put them on a disk, but what do you do just copy and paste them to a disk? Nobody explains. I can't seem to find the chipset driver for this install and I have been getting mmc.exe driver errors. Help please.
Some of the errors are about explorer.exe but there is no explanation. Just explorer.exe is causing slowdown or boot degradation. I have tested the Hard drive and the RAM and everything checks out.
