PC Freezing and BSOD-ing daily

I've just upgraded my motherboard to and Asus M4A785-M. My old motherboard is still functional and runs Windows 7 just fine but when I put my CPU/GPU/RAM and HDD on the new one the system became unstable and began crashing. I've reinstalled Windows 7 a couple of times, each time formatting the C: partition but that didn't fix anything.
I keep getting blue screens and crashes, some of the messages were about irql not less than equal, a problem with tcpip.sys, memory error.
I really want to know if the new MB is the problem and if there's anything I can do about it.

Ok where to start


1-ASACPI.sys. the 2005 rev. usually causes BSOD's

ASACPI.sys Sun Mar 27 22:30:36 2005

The 2005 version of this driver is a known BSOD cause.
Please visit this link: ASUSTeK Computer Inc.-Support- download_item_mkt
Scroll down to the Utilities category, then scroll down to the "ATK0110 driver for WindowsXP/Vista/Windows 7 32&64-bit " (it's about the 8th item down).
Download and install it.
Go to C:\Windows\System32\drivers to check and make sure that the ASACPI.sys file is date stamped from 2009 or 2010 (NOT 2005).

2-SPTD.SYS also a huge cause of BSOD's
Please remove any CD virtualization programs such as Daemon Tools and Alcohol 120%. They use a driver, found in your dmp, sptd.sys, that is notorious for causing BSODs. Use this SPTD uninstaller when you're done: DuplexSecure - Downloads

You can use MagicDisc as an alternative.
