Windows 7: Windows wont start in any way. BSOD 0x0000007E and acpi.sys

19 Feb 2012   #1

Windows 7 Ultimate x64
Windows wont start in any way. BSOD 0x0000007E and acpi.sys

As the title says, I cant start windows because it just blue screens for everything.

-startup repair
-reinstalling windows 7

The main errors I've gotten are the ones in the title.
There are some others but the computer restarts before I can read them.

This all started when I woke up yesterday morning and my laptop was off when I turned it on I got the BSOD error SYSTEM_SERVICE_EXCEPTION and since then its just been crashing.

Oh and its an ASUS G73JW in case it matters.

EDIT: 0x0000003B aswell, sometimes it sticks on the starting windows screen, not frozen though, the logo still 'breathes'.

I Removed all my RAM except for 2 sticks (1 of which I couldn't remove without disassembling my laptop) and everything works fine now.

Sounds like you have hard disk errors. Use Advanced Boot Options to select Repair Your Computer and get to the System Recovery Options. Then select the command prompt. Do the following:
chkdsk /r c:
chkdsk /r d:
chkdsk /r e:
chkdsk /r f:
.etc until you get the message that the volume could not be opened for direct access. For any drives that do not give the message:
"Windows has checked the file system and found no problems"
run chkdsk again as above. In other words, if it says:
"Windows has made corrections to the file system"
after running the disk check, run the disk check again.

I realize you may only have one disk show up in Windows explorer, but you may have more than one disk through recovery options. This is because the system creates a hidden boot partition (which will be C: in recovery), you may have a recovery partition for your PC that is hidden (which will be D: in recovery), and you will have your primary Windows partition (which may be E: in recovery). A custom PC will likely have at least C: and D: to scan.
