After I got my PC free of malware/spyware, I started getting BSOD. After a non-destructive recovery I had to reinstall some programs and drivers, because my programs were no longer opening. I reinstalled most of my programs and my machine seems to be working fine except for a random BSOD. The only thing that I can say is, it seems like I get the BSOD when my audio interface is on and/or when my Sunbelt firewall is on.
I don't know if deleting and reinstalling my interface driver and changing my firewall will make a difference...

Have you reinstalled your chipset and audio drivers? Try that now, get the latest ones from the manufacturer's website.

I got the latest audio driver from Presonus (my audio interface), but I do not know which chipset drivers to download. How do I find out which one I need?

[Troy]

They will be on your motherboard's webpage. Do you know the make/model of your motherboard - or make and model of the whole system if it is a prebuilt?

I have an HP a450y. I believe it has a ASUS P4SD-LA motherboard. I can't seem to find it on their webpage though. It looks as though this is my chipset:
i865p/pe/g/i848p

interesting ...ASUS does not list your mobo at all...is this a home built system
we can get the chipset drivers here though...just click on the check your system for the latest drivers bar
install any it has for your system...reboot and test your sound again
no joy...
launch everest again...this time click on the + beside multimedia and devices...you will have to click on
PCI/PnP Audio
or in the devices section
physical devices
PCI devices...
look all thru both sections...were trying to found what sound devices you have

Everything inside of my tower is factory-installed. I looked there (ASUS) for my motherboard too...
All the drivers on the Intel link page are current.
My audio still works.
In the past three days since I installed a new Presonus (audio interface) driver, I have yet to get a BSOD.

In Everest, under multimedia, under PCI/PnP, I have the following:
intel 82801EB-ICH5 AC'97 Audio Controller [A-2/A-3]

Below is a screenshot of what I got under devices>PCI devices:

[MaxMurder]

That's what I'm thinking, everything seems to be running fine.
Thanks for the help!

[happyrock]

your welcome...and thanks for letting us know...

Agh! I spoke too soon. I got the BSOD last night.

A problem has been detected and Windows has been shut down to prevent damage
to your computer.

The problem seems to be caused by the following file: ALCXWDM.SYS

UNEXPECTED_KERNEL_MODE_TRAP

If this is the first time you've seen this stop error screen,
restart your computer. If this screen appears again, follow
these steps:

Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer
for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware
or software. Disable BIOS memory options such as caching or shadowing.
If you need to use safe mode to remove or disable components, restart
your computer, press F8 to select Advanced Startup Options, and then
select Safe Mode.

That's your audio drivers alright, related to Realtek AC'97.

Try downloading the latest directly from Realtek's website here:
http://www.realtek.c...p;GetDown=false

Completely uninstall all your current sound drivers, reboot and install the latest from that link and see how we go.
