Even though you haven't installed any drivers, Windows 7 will install many if not all drivers. Depends upon the drivers. I would definitely install the Intel Chipset Info drivers and Intel TPM driver. MSI has all the drivers you need at their website. Click
here.
Also it would help for you to install the latest Realtek audio drivers available from the MSI link above.
The MS default drivers for your ATI Radeon card should work okay. IF you want the latest driver; click
here.
Updating your mobo drivers should help with the issues you're having with CPU-Z.
Store the drivers on another hard drive or CD-RW or Thumb Drive for future installs.
I hope this helps you out. Good Luck!
