Lots of stop errors on my new PC

it looks like the PSU expert (mpilchfamily) missed something,

if you look at the specs of the PSU, it has only 450watts and 18A on the + 12V rail.
this is not enough for this setup i think?

correct me if i'm wrong, mpilchfamily

thanks for correcting me and not flaming me,
I checked the label on the FSP site, no data on the combined 12V rail ;-)
but, now we are back to where we started,
----------------------------------------------------
1ste error:

first error is afd.sys
this is a file from winsock
-----------------------------------------------------
second error:

(google)
The Stop 0xC2 message indicates that a kernel-mode process or driver incorrectly attempted to perform memory operations in the following ways:

* By allocating a memory pool size of zero bytes.
* By allocating a memory pool that does not exist.
* By attempting to free a memory pool that is already free.
* By allocating or freeing a memory pool at an IRQL that was too high.

This Stop message is typically due to a faulty driver or software.

Possible Resolutions:

* A Stop 0xC2 messages might occur after installing a faulty device driver, system service, or firmware. If a Stop message lists a driver by name, disable, remove, or roll back the driver to correct the problem. If disabling or removing drivers resolves the issues, contact the manufacturer about a possible update. Using updated software is especially important for multimedia applications, antivirus scanners, DVD playback, and CD mastering tools.
* A Stop 0xC2 messages might also be due to failing or defective hardware. If a Stop message points to a category of devices (such as disk controllers, for example), try removing or replacing the hardware to determine if it is causing the problem.
* If you encounter a Stop 0xC2 message while upgrading to Windows XP, the problem might be due to an incompatible driver, system service, virus scanner, or backup. To avoid problems while upgrading, simplify your hardware configuration and remove all third-party device drivers and system services (including virus scanners) prior to running setup. After you have successfully installed Windows XP, contact the hardware manufacturer to obtain compatible updates.

third error:

Ks.sys is part of the AVstream function (some support files for multimedia applications, this error is probably caused by the gfx or sound driver.

-----------------------------------------------------
fourth error:

already solved?

it looks like a bad videocard or videocard driver?
or a bad sounddriver. try to disable the soundcard (bios!)
if not, try to swap videocards with a friend or other computer lying around?

keep us informed.

The obvious first step is to go back to stock speeds and see if you can replicate these errors.

Just sounds like you have a unstable overclock imho

Thanks for the suggestions, guys.

All of these errors, except the BAD_POOL_CALLER have occured at stock BIOS settings. Once I started getting errors, I imediately un-OC'ed my system, but the errors persist.

They seem to occur at random, too. I just got another new error when I tried to open firefox.

BAD_POOL_HEADER
STop: 0x00000019 (0x00000020, 0xE1386000, 0xE1386808, 0x0D010800)

How would I go about checking my PSU? Voltemeter?

I think I'm going to try a memory test next. You guys recommended, memTest86+, but I've only seen version of memTest86+ that can be run from bootdisks. Is there any way to run it from windows?

Barring that, I'll test the video card. I've noticed that my screens will occasionally flicker to black then back on a few times in rapid succession. It's very quick, but it's there. Seems to happen when I open or close applications. Not sure if that's indicitive of a faulty card or not. I might try borrowing a card from someone else and seeing if that's the problem or not.

so windows can be hurt from overclocking?
how exactly does it happen?


as i said from the beginig : start with memory and see if you can roule it out.
if it shows errors the os is not the problem. it could be basically the psu or the motherboard or, of course, the ram.

if it doessnt show errors than at least you know you have good ram.
It can still be psu or motherboard or the gpu.

Actually you should begin with booting another os (as linux from livecd) to see if it misbehives too.
you can get a lot of information this way.

This may be one of the problems try this or reinstal windows, who knows, there are many drivers and parts that dont work well without the fixes, and ocing inproperly will and can lead to hd errors like you are getting.

Ok, I ran memTest86+ and my computer failed miserably within 10 minutes. So I'm thinking it's the RAM. I'll be calling NewEgg tomorrow and have them take it back (only had this stuff about 15 days) and I'll pick up some better RAM modules.

Sorry, I usually don't post any type of inflamatory remarks but that is the Dumbest thing I have ever heard...
How do you corrupt your OS by overclocking your hardware?

I work in the support business for a living and where I do not claim to know everything I believe that I can say with some measure of confidence that it is not possible to corrupt your OS by overclocking your PC UNLESS you have f'd up your HDD in the process....

As for the OP's errors, they point most assuredly to Faulty RAM that was probably damaged when he OC'd his system... I have run into his "DRIVER_IRQL_NOT_LESS_OR_EQUAL" many times and 99% of the time that points to Bad RAM...

Any time your system crashes you risk data corruption.

I don't know what kind of support you do, but where i come from we eliminate all variables and take a course of action.

Best course of action in the OP's situation is to

A. Eliminate his hardware being an issue by putting it at stock settings.
B. Eliminate his OS as an issue by reinstalling it fresh.

Trying to troubleshoot your OS while its possibly corrupted, and with your system overclocked, is just plain idiotic and a waste of time.

You can also test one ram module at the time.
It should be unlikely that both af them are bad.

If one of them is good and the other is bad than it is a memory problem.
If both are bad than you either are in bad luck or it is not the memory and you should test the psu.

OS corruption can occur with overclocking. Theres no "its not possible". Its VERY possible.

Uh, duh, whenever your system crashes you can damage OS files that are in use. I've experienced MANY corrupted files from overclocking-related crashes.

Get ready to slap your forhead then, because "f's up HDD" can also refer to the data on the drive, not just a physically damaged drive. I work in the support business too, and I've seen one crash damage one OS file before, from overclocking

That last comment was the first smart thing you said.

Ok, so this is weird.

As my part list states, I have 2x512 sticks in my machine, giving me a gigabyte of ram. I had the RAM running in interleaved mode. I don't know exactly what interleaved mode does, but it sounds like it's faster than single channel mode.

So when I ran MemTest86+, it failed within 10 minutes. I took out the RAM and tested each module seperately, one at a time, in both of the DIMM slots on my motherboard. Both of the RAM chips passed the tests running for over 12 hours straight, no errors. Then I tried putting the RAM in single channel mode, it failed within 10 minutes. I tried putting it back in interleaved mode, still fails within 10 minutes.

So...1 RAM module and my computer is fine
2 RAM modules and my computer is mysteriously unstable.

Any ideas why?

I dont know why but some memory modules just dont work together, but work well with other modules or alone. I used to make lots of test using different motherboards,

I experienced this alot with old pc100/133 sdrams. I dont know about the new ddr and ddr2. I think it isnt that usual nowadays.

The interleaved mode is i suppose that (while using up memory) instead of filling one module first and then the other you fill them both : one byte to one module, one byte to the other module; one byte to one module, one byte....
or similar.
Im not sure if thats what the actual dual channel mode is.

Another cause could be the psu. 2 modules use more power than one and if psu is faulty it might not give enough.

The module incompatibility that i mentioned above shouldnt of course be the issiue if the modules are indeed identical.
In that case i would turn my suspicions towards the psu and the motherboard.

It could help very much if you found a friendly soul with similar hardware to test yours.

You know - the memory slots you choose to use can matter too.Maybe your motherboard has a preference, like using slots closer to the processor first...


Maybe your memory simply isnt compatible with the motheboard.

Anyways it will be hard to troubleshoot without a reference system that works.

cab driver less equal at stop signs or equal as a noob

Looking at your original post, i really don't see a problem with that power supply running the equipment you purchased.


Few things to verify. Is your ram really 1.8v ram? Check the specs again just in case you are undervolting.

Also, you said you were runnig your e6300 @ 1.300 volts. Isn't 1.320 stock? Just some other things to look at.

But Yea it looks like you may just have incompatable ram.

Replace 'talent' with 'breasts'.
