Frequent, random BSoDs for over a year

Hey, I keep getting random BSoDs. It usually happens either shortly after I cold-boot, or several hours later when I'm idling while doing homework somewhere else or something. The error codes and system files in question are not consistent.

They used to happen once every few weeks, but they've been getting more frequent; at least once a day, usually twice, occasionally three times. It seemed to start happening much more often after I upgraded my gfx card from a 9800 GT to a GTX 460.

Since the BSoDs started, I've upgraded every single piece of hardware in my system except for the following:

• PSU
• RAM
• Motherboard
• CPU

I have a new PSU coming in the mail... gotta narrow it down I guess :P I'm inclined to believe it's a power issue, but only barely.

Memtest passed on these sticks of RAM.

Speccy stuff:
- Windows 7 Professional x64, student license from school
- PSU, RAM, Mobo, CPU are about two years old
- SSD is 8 months old, HDD is 2 months old, GPU is 4 months old
- Last reformat was 8 months ago (with SSD purchase)

Dumpy stuff is attached.

Hello JeffMan,

We need to remove these two problems before we can tell the true cause of these crashes.

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 (and before) of this driver is a known BSOD cause.

Please visit this link: ASUSTeK Computer Inc. -Support- Drivers and Download P7P55D LE
ASUSTeK 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).


2-SPTD.SYS

This is another large cause used by daemon tools and alcohol120

Remove any CD visualization programs such as Daemon Tools and Alcohol 120%.
They use a driver, found in your dmp, sptd.sys, that is notorious for causing BSODs.
Use this SPTD uninstaller when you're done:

You can use MagicDisc as an alternative.

Hi JMH,

Thanks for the reply!

BIOS: The motherboard page you linked to was for a different model. Mine is actually a P5QL Pro. Although the BIOS files for the P7P55D are much newer and probably better, my model only has a 1MB flash so I had to use the file from the P5QL Pro page instead. The datestamp for it is August 2009, hopefully that's new enough.

ATK0110: The P5QL Pro page has a 2009 version, so I went for that one. I checked the ASACPI.sys file and it's now datestamped for 2009.

SPTD.SYS: Huh, interesting. Didn't know those things could be a problem. Thanks for the tip, I'll get those fixed.

Thanks for reporting back. :)
Let us know how it goes.
