Having computer problems

[grayg1]

Firstly, I am not overclocking and everything is stock.

After I installed Windows XP I was getting page fault in nonpaged area BSODs. I managed to get rid of this by doing an XP repair.
However I have still been having problems with games having random 2-3 second pauses SOMETIMES. By that I mean sometimes I won't get any stuttering and then when I go on my PC later on I will get them.

Far Cry seems to like to work when I start a new game but doesn't like to work if I load a save game file and crashes with a BSOD 0x0000007F error. Which translates to a divide by zero error which says it is either a RAM or video card fault.. If I swap to a different graphics card I get the same error, however the RAM can pass memtest twice without errors (which is about 40minutes worth).
My hard drive passes all SeaTools tests except the parition test, which I later learnt it fails because SeaTools doesnt support NTFS file systems in the partition test.
Tried different drivers for my graphics card same results.
Using latest BIOS.

Obviously I am getting faults which point the finger at the RAM but how can it pass memtest?

What the hell is going on?

Can you remove one RAM stick to try them individually?

Far cry still does same thing with either stick on their own

Unless both sticks are goosed I would suspect there is nothing wrong with the memory.

Do you have another graphics card you can try?

Yeh I swapped out my 7800GT with a 7600GT and same problem.

i am starting to lean towards software corruption but it seems to keep happening so there has to be something faulty making stuff go corrupt. But everything passes all their tests to say they aren't faulty O_o

I have kapersky anti virus and it hasn't found anything so assuming it's not a virus.

I have reinstalled directx numerous times too. Also tried setting affinitys on games so it only uses one core too.

MS info:

offers three suggestions:

corrupt memory, mismatched memory or a failing motherboard.

You PSU seems to be perfectly capable of running what you have so I would guess unless that is on the way out that it could be a motherboard prob but, then again, you would also think it would fail on memtest.

A few of the links on my google search point to probs with anti-virus software and low kernel stacks. You can have a look here:

It better not be the motherboard, I only sent a faulty one back last week which refused to even start up.

Think I should just format the HD and start again?

I have tracked my Far Cry crash down to the Realtek sound driver if the windows dubugger is telling the truth anyway.

Well, I hope you have isolated the cause. If there is any way I can help, let me know.

[grayg1]

Well tested far cry with no audio driver installed and save game loads up fine.

Still have to test to see if my stuttering is gone.

looks like you'll be buying a PCI sound card shortly

Glad you got to the bottom of things - it's really frustrating when you can't find the cause.
