I assume that this is a Desktop computer (but you know the saying about "ass-u-me") - so, if I'm mistaken, please let me know.
Please update this driver as it's known to cause issues in Windows 7:
ASACPI.sys Thu Aug 12 22:52:52 2004
This is a driver available at the Asus website under the Utilities or Other heading for your motherboard. Please get the Windows 7 version of:
AINap (or something similar with "nap" in the name)
Then, after installing it, check the date stamp on ASACPI.SYS in the C:\Windows\System32\Drivers directory.
Then please monitor for BSOD's, and post the next one that you get.
