and I have to try some times to make it successfully boot.
I'm using Windows 7 Ultimate x64 and the hardware is about 3 years old (Intel C2Q Q9450, ATi HD4870, ASUS P5Q Deluxe) and not overclocked.
I have attached the files suggested in the sticky.
Two problems are immediately apparent. First
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 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-Memory corruption caused by an un-named driver. Please run these two tests
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.
I'd suggest that you first backup your stuff and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Windows 7 Startup Repair feature).
In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .
Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.
Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).
If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.
