Hi All,

I recently new Corsair 400 R Cabinet, Corsair H100i CPU Cooler and Corsair VS 650 Watts PSU.

So I had to reassemble my Motherboard (ASUS M5A97 R2.0), CPU (AMD FX 8350) and Graphics Card (Zotak Geforce 8400 GS) and 3 SATA HDD (500 GB + 500 GB + 250 GB) and a DVD-RW Drive.

In total I have 5 Fans installed (Including the ones which comes along with the CPU Cooler and the Cabinet)

Post reassembling the system, my wireless keyboard and mouse does work, It works fine until the Windows (Windows 7 Ultimate SP 1 x64) gets started once I get to the desktop, it tries to install the driver and fails.

Even my onboard LAN card is not getting detected at all.

This is the troubleshooting I have done so far.

I tried disconnecting all the USB devices except the keyboard and mouse, also removed 2 HDD to check whether its a PSU issue - But of no help.

I tried connecting a simple wired USB keyboard and mouse, it works fine until Windows get booted up once I get "Starting Windows" message the keyboard stops working but the mouse continues to work and again it tries to install the USB keyboard drivers and fails.

I tried Fedora Live CD to check whether the issue is persistent over there, here both my keyboard and mouse works fine, also my wireless USB 2.4 Ghz keyboard and mouse works fine but still the LAN card is not detected.

I got into the BIOS to make sure whether the onBoard LAN card is enabled or not, and it was enabled.

I also tried doing a fresh install of Windows 7 Ultimate removing all my other HDD's and using the 250 GB SATA HDD, but the mouse works fine but the keyboard stops working during the installation process itself.

I did check what is the wattage required using the ASUS Power Supply Calculator but it showed my as 500 Watts as recommended.

Since my LAN card is not get detected I'm unable to update the drivers as well.

I also tried to update the USB Keyboard drivers using the Windows 7 install disk but it doesn't find's any drivers.

As far as LAN card is concerned since the LAN card isn't getting detected it is not letting me to install the drivers.

I'm not sure why my LAN card is not getting detected, whether it is the motherboard issue or PSU issue.

I'm totally pissed off, looks like I screwed my system which was working fine with my own hands.

Since I don't have any higher range PSU I'm unable to proceed with further troubleshooting.

Any suggestions would be really appreciated.

Thanks in Advance.

Solution
Can you download the drivers for your motherboard on another computer, put them on a flash drive, and boot into safe mode to install them?
Hello... Did you make or have "REcovery Disk" when everything was running good? that would be the fastest Driver/system restore for you...
Yes, Go to another Computer and DL MB chipset drivers, Lan... Remove the OLD drivers while in safemode too... and reboot before installing them... MAKE SURE you have the "Correct MB revision" drivers that can make a difference too!!! it is painted on Your MB.

No I didn't make a Recovery Disk, I did try to uninstall the chipset drivers, but it is not letting me to unistall it and for LAN it doesn't shows up at all.

Don't know what to do. :(

Really appreciate your help.

Thanks.
