A problem has been detected and windows has been shut down to prevent damage to your computer.
If this is the first time youve seen this stop error screen, restart your computer. If this screen appears again, follow these steps:
The BIOS in this system is not fully ACPI compliant. Please contact your system vendor or visit http://www.hardware-update.com for an updated BIOS. If you are unable to obtain an updated BIOS or the latest BIOS supplied by your vendor is not ACPI compliant, you can turn off ACPI mode during text mode setup. To do this, simply press the F7 key when you are prompted to install storage drivers. The system will not notify you that the F7 key was pressed - it will silently disable the ACPI and allow you to continue your installation.

This occurred after a power failure. Now it happens maybe 50% of the time, and the computer reboots. I've eliminated the hard drive and os as causes, flashed the bios to the newest available version, and the ram passes memtest with no errors. The only thing I can think of is replacing the ram, but I don't want to buy memory if it won't help the problem. Any suggestions? Thanks much!
