Major OS Slow-down Upon Chipset Install

Yesterday I purchased an Asus P8Z77-V LX motherboard to replace an older Asus mobo, which had begun to break down. Hardware installation went smoothly, and the OS reinstall had no hiccups that I could see.

However, there appears to be a serious problem with the chipsets supplied with the support DVD. While the ethernet, USB 3.0/etc drivers install and run just fine, the chipset behaves abnormally as soon as I click to install.

Upon doing so, Windows takes anywhere between 5-10 minutes to load. Other programs and processes take a variable length of time to start working, and oftentimes hang or crash before I can do anything.

I have had to reformat my hard drive twice in an attempt to sort out the problem, and so far it seems isolated to the Intel Chipsets provided on the DVD, though I have no idea why. Without them installed everything else on my PC is very responsive, and programs are not hanging or crashing. Chkdsk reported no problems or bad sectors.

Installing the chipset drivers from Asus' support page may work, as I have not tried that yet, but I am afraid of running in to the same problem and having to reformat again -- the slowdown is really hard to work through.

The PC consists of:

ASUS P8Z77-V LX mobo
Intel Core i5-3570K@3.40Ghz
ATA Hard Drive, not sure what the rest of the name in its Device Manager listing means
Windows 7 64bit
PNY GeForce 450 graphics card (currently undetected; have yet to install drivers)
Corsair Vengeance DDR3, 2x4 GB

I haven't made any changes to the BIOS, except for changing the boot order to disk-first.

Is there anything shown in device manager that has a yellow ? mark beside it without asus's drivers installed? If windows is running the chipset fully functional without the drvers installed, and they run worse WITH them installed, they are of no benefit. I ran an asus board last pc, and there was no performance gain with the drivers on the supplid disk,I benched both ways. Afew settings wer different but nothing of worth. If the pc runs fine on Windows found drivers dont worry about it. Updates will change a few of them as time goes on.

What does reflashing it do? Windows Update is running presently, so it will be a while before I can do that.

I also think I have this thread set up wrong, since it's listing all of my responses as solutions on my end.

And yes, you might want to flash the bios.
More and more and more cases of new asus boards with duff bios instals.
I would only buy asus from a pc expert place, where they could flash faulty boards free of charge. Mail order? forget it.

If everything works ok, throw the drivers disc in the bin. !

PCI Simple Communications Controller, SM Bus Controller, and the USB Controller have yellow exclamation points next to them, but I haven't installed the drivers for those yet (assuming they're connected to the USB 3.0 driver on the disc). They are listed as "Other devices."

Nothing else has any indicators next to them. The only thing I've installed from the disk currently is the LAN Controller as Windows was not automatically detecting my connection.

If everything will run just fine without them, what is their purpose? Or is it just because Windows has started to check for things on its own?

Windows comes with default drivers that will work on almost all chipsets. They are just good enough to get your computer up and running so you can update it. Most vendors then have optimized drivers that work better than the default windows drivers on their install discs...you are the exception. Those exclamation points are there to tell you that you are still using the default drivers.

I guess leaving well enough alone is the solution for now. If things become unstable down the road, I'll try installing the chipset from Asus' website instead of from the DVD and if that doesn't work, I'll look in to the BIOS. Thank you very much, you two; this is quite the relief.
