PC has been slower since last format

Ahh so I do not use my CDs, I just have to download them manually from the vendor's webpage, I can use Win7 without drivers, I can access the internet but I'll see everything in 800x600, but If I can access the web, then there's no need to install the motherboard drivers right? Just the ATi from the vendors webpage and then (when every driver is installed) I use Win7 update to update them?




PS: What if formatting does not fix the issue? Because the last time I formatted this happened too (I will format anyways, probably tomorrow!)

Wait! If I don't install Motherboard drivers actually I won't hear some things in games, should I install them or just the video drivers? What if Windows 7 update asks me to download/update motherboard drivers? Should I deactivate automatic updates?

Use the drivers which Win7 installer gives during install, then whatever optional Windows Updates delivers after install.

You can import any drivers from the manufacturer's Support Downloads webpage which are missing after install, but I would not change drivers given by the installer or Windows Updates unless performance problems point directly to those drivers.

Heeelp!!! I've formatted and I installed ATi drivers first (without CCC) but in device manager Intel(R) 82801GB/GR (ICH7 Family) LPC Interface Controller - 27B8 is missing so I installed an old chipset driver version I've found accidentaly, then I installed the newer version, then I've installed audio drivers and lan drivers but it still happens what should I do???

Why are you installing drivers which were not missing in Device Manager?

Did you read what I wrote above?

Sorry xD I've formatted again because I messed up everything LOL , I'm about to do the Boot Trace as cluberti told me

Wait to see if optional Windows Updates delivers that missing chipset driver, then supply only it and any other missing drivers from the manufacturer's Downloads webpage for your model.

Okay, I've done both tests but the problem persists (Could it be that this problem goes beyond software? )

Here's what I did: I installed Win7, I ONLY used the drivers from Windows Update, all of them, when there were no more updates I did defrag C: /u /v and then defrag c: /b (both in an elevated command prompt) in this last one when It finished it said "Could not find files in the registry for boot optimization" or something like that and an error number. So I've restarted my PC as you told me and run a boot trace without any programs other than drivers , said trace is here: Boot_Trace before install.rar

Everything felt just normal, like when I didn't have the problem. So I went on and installed all the programs as I would do normally and when I restarted my PC the start Up took a LOT of time, like 70 seconds (just as before formatting) and then I did defrag again and did another boot trace with all the programs which is here: Boot_Trace after install.rar

Some programs didn't ever appear in the bar next to the time and date but It was a display error because I opened them and still the icon did not appear. Could it be that this is beyond software? I hope I can fix this soon I don't know what could cause this
