Some users are experiencing crashes or blue screens of death (BSODs) under Windows 7 RC1 when attempting to wake systems from sleep (hibernation). The first response to this issue is generally to disable sleep mode, but there is another fix.
Enter your system’s BIOS mode. This is accomplished by pressing a specific key repeatedly as soon as your computer is turned on (or right after it is restarted). For many computers, the key is F8, but it may be F1, F2, F10, the Delete (del) key or the Escape (ESC) key. Consult your computer or motherboard’s manual or try different keys until you find the right one.
Next check your HDD or storage settings. Turn off SATA and reboot normally.
