Vista - Blue Screen during gameplay (Halo 2)

Hi all, I am having problems with running Halo2 for Vista. I keep getting a
blue screen after a few minutes of play.
My system is as follows

-Intel Core 2 Duo E4300 1.8Ghz
-GeForce 8800GTX 768Mb - Installed drivers 163.44(beta), previous drivers
162.22 (same problems)
-2Gb Corsair XMS RAM
-Asus P5N32-E SLi Mobo
-OS - Vista Home Premium 32 bit, clean install

Y'day I got the following 2 different blue screens

i) STOP:0x0000008E (0x00000005, 0x8A81CE34, 0x99334A88, 0x00000000)

-collecting data for crash dump
-Initializing disk for crash dump
-Beginning dump of physical memory
-Dumping physical memory to disk

ii) win32k.sys
-page_fault_in_nonpaged_area
-STOP 0x00000050 (0x80917CC0, 0x00000001, 0x916DF92B, 0x00000000)
-win32k.sys-Address 916DF92B base at 916000000 Datestamp 45d3cc1d

I tried restarting the computer with a clean startup procedure - No Success
I also tried creating a new user account - No Success
My Nvidia driver won't allow me to change the troubleshoot section - Not
Possible
My DxDiag tool won't allow me to switch AGP texturing off - Not possible
I also updated the Video Driver - No success.

Can someone please give me a hand here as it is becoming frustrating to have
to reset the PC every 5mins.

most likely bad power supply or memory.

try pulling a stick of memory and moving the other one round - does error still happen? maybe try failsafe timings in BIOS

tell us what power supply you're using - that is a beast of a graphics card

I am using an XClio Stablepower 850W (x2 12V rails w/total of 70A)

I will try the memory stick switch.

Can you please explain more about the BIOS failsafe timings? (Current memory
timing is 4-4-4-12)

Cheers!

remember are Antec, Enermax, and one that starts with an S.
Think it's just use the default memory settings instead of trying to tweak
the settings. if that's what your mobo says will work you're problably OK.
You might try googling MEMTEST86, make a bootable CD with memtest86 iso.
Reboot with the CD and see if MemTest finds any faults in your ram. Run the
test to completion, or until you start getting a bunch of errors.

Could also try Prime95 for stress testing memory or your CPU in Vista.

Good luck...

Thanks for the help you're giving. For your info y'day I got this blue
screen while playing FEAR:

IRQ_NOT_LESS_OR_EQUAL
STOP:0x0000000A (ox404E9D63, 0X00000002, 0X00000000, 0X81CAF870)

I'm beginning to think it's a hardware or compatibility poblem. It's
probably m memory or Video card conflicting with something. I will try
memtest and let you know later.

Memory switch had seemed to solve the problem as I played FEAR for a good
15mins but then I got a message that 'Windows Explorer had stopped working'
and soon after got a blue screen.

The PSU got some very god ratings everywhere I read a review on it. It got
good ratings for delivering constant stable power so I guess that's ok. I
still think it's a hardware problem.

Cheers

wow, that's a very beefy power supply, plenty of juice but it does produce heat along with the graphics card

i believe you may be overheating. check your cpu and system temperatures - either in windows with asus utility or start bios right after crash and check pc health status.

try blowing some air at comp with outside fan and see if that helps.

sandra program will list the speeds supported by your memory - but i dont think its memory problem any more.

CPU temp is 25deg celsius constant (Use liquid cooling)
System temp is at 35deg celsius constant too

I do not think it's an overheating problem.

Memtest gave me an error btw but after an overnight memtest session it hung
up but I definitely have at least 1 error.

Today played FEAR for a solid 30-45mins before it crashed (w/out blue screen
, less frustrating at least

Thanks all.

You might try this patch here and let us know if that worked.
It addresses some paging/memory issues within Vista.

i had a similar problem with the corsair memory a while ago - it requires higher voltages 2.2V - the BIOS was not providing the right voltage but a BIOS update fixed it.

things to try: download sandra from download.com and under mainboard info find out the other timing modes supported by the memory - then try 1 of the slower modes

check and see your memory is getting right voltage (in the BIOS) , maybe bump it up by 0.1V.

update BIOS if not up to date i think asus can update from vista

visit corsair forum

i can see you've put a lot of effort and expense into this system but there is no reason it will not work - good luck

...or alternatively for an easier time .. purchase a small stick of kingston ram - it always boots at 1.8v and may permit faster modes if available - if that works get more - i always keep a stick handy to diagnose memory problems - thanks for reminding me why i dont buy high voltage ram anymore
