Windows 7 Random BSODs and freezes


New Member

Hi everyone. I've been having problems with random BSODs/freezes/restarts for quite a while now. Today I made a clean install of windows 7 professional SP1 after breaking the RAID 0 of my hdds. I had another BSOD though while playing Lineage 2. I have attached the .rar with the report from the W7F diagnostics tool plus CPU-Z and RAMMon.
System specs:
M/B:Asus P5Q3
CPU:Intel Core2 Quad Q9550 @ 2.83GHz
RAM:2xCorsair 2gb 1333Mhz DDR3

edit: I just did a bugcheck analysis on the minidump, so here goes:probably caused by : atikmdag.sys ( atikmdag+2c2949 )

Checked the said driver: atikmdag Kernel 18/8/2009 6:05:47 §£
I think it's out of date... Can someone post a link for a newer version?

Google says this is the chipset of your video card: Radeon HD 4870
Updated drivers are here: AMD Catalyst? Driver for AMD Radeon? HD 4000, HD 3000 and HD 2000 Series

Please note that these are Legacy drivers (it means that they won't be supported much longer - and they may have older components in them).
As such, please install the DRIVERS ONLY using this procedure: ATI video cards - DRIVER ONLY installation procedure - Sysnative Forums

Only 2 Windows Updates installed. Most systems have 160 or more. Please visit Windows Update and get ALL available updates (it may take several trips to get them all).

You have the 2005 version of ASACPI.sys - which is known to cause BSOD's on some Windows systems. Please visit here: ASUS - P5Q3 , then select your OS (Win7 64 bit).
Then click on the Utilities section.
The first item is "ATK0110 driver for WindowsXP/Vista/Win7 32&64-bit" - download and install that to update this driver.

Please update these older drivers. Links are included to assist in looking up the source of the drivers. If unable to find an update, please remove (un-install) the program responsible for that driver. DO NOT manually delete/rename the driver as it may make the system unbootable! :

Rt64win7.sys Thu Feb 26 04:04:13 2009 (49A65B0D)
Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC

If all of this doesn't stop the BSOD's, please run these free hardware diagnostics (particularly the video tests): Hardware Diagnostics. Let us know the results and we can move on from there.
