PC restarts, BSOD on cold reboot

Hi guys,

I seem to encounter another problem today with my computer. After using it last night and booting it up earlier this morning, I got a BSOD with a PFN_LIST_CORRUPT as its reason. I tried to resume loading Windows 7 normally, however it restarts a few seconds upon a successful user log in. I switched to Safe Mode and then performed a sfc /scannow on the command prompt (three times), with 2 results saying it encountered no problems, and one being unable to finish.

Anyway, I can't run a perfmon test successfully in Safe mode, but I managed to get the dump files somehow. Attached below would be the dump files.

I'd really appreciate it if someone can help me fix this.

Memory corruption after SP1 was installed. Also asacpi.sys is a huge cause of bsod's

1-ASACPI.SYS a major cause of BSOD's in the 2005 rev.

The pre 2009 version of this driver is a known BSOD cause.

The 2005 version of this driver is a known BSOD cause.
Please visit this link: ASUS teK Computer Inc. -Support- Drivers and Download P7P55D LE
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 12th 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).



Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program.

Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

OK, I've just downloaded and installed the asacpi.sys from the ASUS website. Checked the System32\drivers folder and it's dated 5/14/2009. Also downloading the Memtest and making a USB bootable version of it.

Just a question though: An earlier problem (I think the thread is still here somewhere) resulted to me updating the asacpi.sys file to a later version (I remember downloading the same file before too). How come it reverted to an older version after installing SP1?
