Blue Screens

System Information: (GT5428 from gateway)
1 Gig DDR2 (Dual Channel 512MB x 2 667 MHz)
250 GB Harddrive (WEstern Digital Model wd2500js)
Intel Pentium D 935 Dual-Core processor (3.2 GHz)
Ultra 400 Watt Power supply
Sapphire Radeon 2600 Pro (512 MB DDR2 ram) (Minimum power supply 400w)
Windows XP Professional SP2
On-Board Audio
Intel Motherboard (I don't know the model)


But this is the problem, every so often out family computer (the one I'm posting on) will receive a blue screen so I made it so XP doesn't auto restart and these are the errors I'm receiving.


IRQL_NOT_LESS_OR_EQUAL
stop: 0x0000000A (0xC03F0120, 0x00000002, 0x00000000, 0x80510C42)


and

Win32k.sys Blue Screen,

I tried reinstalling XP (Didn't fix it), I tried reinstalling with the Vista DVD that came with the computer and that didn't work, judging by the first error I though it was something to do with the page file so I reset it (removed --> reset --> Defragged --> Reset ---> Set page file --> reset --> posted this)

but I don't know if thats the real reason and the Win32k.sys I've never had before and google only verified that Microsoft knows its an error with Windows XP SP2.

Any help I could receive would be very helpful as I've tried everything I know and I haven't been able to fix it. Also these blue screens happen at random times it's not specific like when I open games, emails, browsers, other applications.

Sincerely,
ItWasLuck.

Programs I have installed:
JK Defrag
Advanced Windows Care Personal
IOBit Smart Defrag (Auto-Defrags every Saturday)
CCleaner
Comodo Firewall
Comodo Anti-Virus

those are the only real programs worth mentioning. Also I don't know if this is any help but I'm running the Western Digital Data Lifeguard Diagnostics program to test my harddrive for bad sectors. And this might be worth mentioning but whenever I download big files (300MB+ normally) they are normally always corrupted if .rar / .zip or they just start missing files or the files are corrupt in .exe's.

 

Try running memtest and see what you get on it.

 

Since Win32k.sys handles the directX calls from the graphics subsystem and since stop error 0xxxA is associated with drivers I would look closely at the graphics drivers.

(This is true in all NT systems from NT to Vista)

How did you get XP drivers for your graphics, since you originally had Vista?

My second area of concern would be Comodo. Turn it off and see if that prevents the problem.

 

Comodo is turned off and I downloaded the latest drivers from http://ati.amd.com/support/driver.html.

I found out about Win32k.sys and the driver problems and uninstalled the 8.XX drivers I had installed and replaced them with 7.12 they work now but I have developed another problem.

Memtest86+ reports no problems with the ram but I'm getting "Memory_Management" errors which doesn't give an error code and gives no nothing like a .sys file that the error is coming from so I believe theres something Malfunctioning.

 

I think your power supply is marginally adequate. So if these new errors occur when you are pushing the system look in that direction.

 

I'll try another power supply (500 watts). Also I believe this is a Video Card problem because I just received (From what I could see) as a Duag.dll error which I believe happens because of ATI Driver conflicts. But these ATI Drivers are a fresh install and I don't know a specific file thats its conflicting with.

And I just recieved a 0x0000008E error, these errors seem to be happening more frequently as I use my computer.

 

You could also look at your version of directX.

 

DirectX 9.0c (4.09.0000..0904)

Also as a correction to my previous post the error isn't Duag.dll its ATI3Duag.dll, and I opened an error report with ATI to see what they have to say about it.
