Lately, I've bought a sony vaio yb with E350 apu. It came preinstalled with a lot of crapware and win 7 32 bit home basic/starter. I installed my own win 7 64 bit pro. Now I can't find many drivers for it. Where can I find chipset, sata, card reader, and other drivers? I can get wifi, ethernet, blutooth, cpu,gpu drivers with a little googling but the missing drivers seem to lower the performance a bit.

It would be really grateful if someone can solve this problem. My computer sometimes fails to wake from sleep, or from hibernate. And it runs hotter that it did on 32 bit.

You need to make a list of hardware ids of the drivers you are missing, everest, aida64 or hwinfo can do this

BTW a good site for finding OEM drivers by the HWID is this one
