BSOD and hard-lock

Generally three problems occur.

1. I get a random BSOD
2. The computer just hard-locks, can't do anything have to reboot.
3. The screens go all crazy and hard locks (they look a lot like those paintings that you have to stare at for a long time to see the picture underneath)

The computer ran just fine for about 2 months before I started getting these lock ups and BSOD's, I do have a child (14 months) that would often run up and just push down on the button to turn off the computer.
I find that my left monitor flickers a little bit when i have a browser up, I RMA'd that and the new one did the same thing so I figured it was something to do with the video card.


Things I have tried.

1. Ran memtest86 for 8 hours, cycled through the tests 4 times, no errors
2. RMA'd the board and CPU
3. Installed a friends HD 5770 (his is the nighthawk version and mine is the normal one)...possible that the problem caused during this test was a bad stick of ram that I found later.
4. Used a different Hard drive (can't guarantee that the one I tried was good though, so that doesn't mean much)
5. Re-installed windows 7 about 4 or 5 times, sometimes not installing any drivers sometimes installing all that I could find, sometimes installing older versions of drivers (AMD 11.5 instead of 11.6...video card), sometimes installing vista and then upgrading it to 7, sometimes just running vista.
6. Whenever I installed a new driver I would go launch driver sweeper and make sure the old one was deleted first.


Basically I am at a loss and I would appreciate the help, Thank-you all in advance

Start here


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

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).

Thank you very much zigzag3143, I hope that is my only problem :)

Updated driver and the computer stayed up for about 30 minutes and then did the fuzzy screen thing with a hard lock, rebooted and it stayed up for about 2 minutes and BSOD (didn't create a dump file this time), tried to re-install windows but I am now getting hard locks during the install process, which points to hardware right? just which part lol.

It usually does point to hardware. First pull all the ram but one stick if you can. Sometimes it actually wants less memory when installing.

You can also check in msconfig to see if max memory and floppy support are unchecked.

Yeah those are unchecked hardware is all jacked up right now (wont stay up long enough to do anything), going to RMA everything lol
