LAPTOP: DELL INSPIRON 1545 ___ OS: WINDOWS 7 HOME PREMIUM

Hey, a couple months ago my mouse stopped working. I thought it was a driver problem, but windows said my drivers were up to date. Today, I got two driver updater programs, both saying I had 21 out-of-date drivers. I found most of them, but I still have 16 out-of-date drivers.

I need to update:

(5)Intel(R) ICH9 Family PCI Express Root Port 1 - 2940

Intel(R) ICH9 Family SMBus Controller- 2930

Mobile Intel(R) 4 Series Chipset Processor to DRAM Controller - 2A40

(8)Intel(R) ICH9 Family USB Universal Host Controller - 2934

Marvell Yukon 88E8040 PCI-E Fast Ethernet Controller

I'd REALLY appreciate help with this!

Also, here is something that Windows itself says may need to be updated: AWW4RH7U IDE Controller under the storage controller section. Where would I download this? Some person said it was a part of the motherboard. My motherboard is made my Dell and Model # 0G848F
