Random system crashes-Power supply?

[arnies5]

I'm looking for some help please.
I'll start with my system:
Antec Sonata II Case SP450 power supply
AMDAnthlon 64x2 Dual Core 3800+ Processor
ASUS A8N-SLI Motherboard
GeForce 6800 GS Video Card
Sounb Blaster Audigy
2 gig RAM
250 gig Seagate SATA Hard Drive

I'm getting crashes and various blue screen errors such as:
A THREAD TRIED TO RELEASE A RESOURCE IT DID NOT OWN
IRQ NOT LESS_OR_EQUAL
0X000000E3 (***) some memory location I think.
0X0000008E (***) some memory location I think.

I have updated my drivers for the video card, chip set.

I'm thinking my next two places to look are:
Update the BIOS and look into the power supply.
I contacted Antec and they tell me the power supply is NOT SLI compliant.
I guess my question is which would be the most likely cause of my headaches?
Would updating the BIOS help?
Would the power supply cause these errors?

I would be inclined to say the problem may be due to a ram problem,
you could run memtest32 and see if you get any errors. that would be the first thing I would try.

I'm new at this. can you tell me how to run memtest32? Is it a downloaded program or a system program?

You can get memtest here

www.memtest86.com/

you can download an iso and burn it on one of those tiny cd-r's (I burn an image using Nero, it's gotta be an image or it won't boot) and you boot your computer up with it and it runs tests on the memory. You can let it run for hours or days, but that's no fun. I think if you go through one pass and have no problems, then the memory is fine.

Another thing you might try is moving your sound card to a different PCI slot. I was just reading somewhere else today that the top PCI slot can cause problems in the A8N-SLI.

I'll try moving the vid card. Remember I'm a newbie. I can burn cd's but I'm new at this sort of thing.
Image? do you mean a data copy?
iso?
Thanks for the help.

In Nero, I select "burn image", which is different than just a plain data disk. Then when I go to select the file, I have to do the drop down on the file types to select iso type files, since it doesn't come up automatically.

I think when I downloaded memtest, I downloaded a zip file and had to extract it first, before I burned the image. I extracted it to the desktop, so it was easy to find.

I'm a newbie too, I've just had a little success with a couple of things.

I forgot your motherboard had two pci-express slots, I was talking about the pci slots, the three shorter slots towards the bottom of the board, where I assumed you put your sound card. I thought if the sound card was in the topmost slot, maybe moving it down would help.

Sometimes, just reseating things can work. Hope you get it going, it looks like it would be a swell rig.
