OK, I've had a few crash problems with a new AMD system I just built but I'm forgetting those for the time being and focussing on an immediate problem.

I've got a similar problem worse...
It functions fairly well for most things but my dad (who I sold the computer to) brought a USB2.0 analogue video capture box thingy. It now crashes every time WITHOUT FAIL when you try and capture. It previews the image ok but as soon as you record you get 5 or 6 seconds worth and then reboot - or if u turn off the reboot option you get one of those blue screens stating a long memory address and at the top says something about IRQL LESS THAN OR NOT EQUAL TO...
and at the bottom mentions the file Cscamd20.sys
My problem now is that the device works ok on my P4 and my dad is going to take my P4 mobo and chip in exchange as he claims I've sold him a dud !!

I don't know if it's an outright AMD fault or a problem with the motherboard. It says on the box p4 1.0g or equilavent so I assume that means AMD. If I knew the mobo was definitely causing the problem I'd go buy a new one but I don't wanna buy a new one and find out that its another incompatibility. It's a cheap ass 'asrock' I've done a complete fresh reinstall of XP and get the same problem so theoretically its not an OS issue (unless its a default setting that disagrees with the capture process) I also tried swapping the ram with a strip of 128m sd I had laying around (the mobo takes both ddr and sd) and it did the same thing so that rules the ram out.

Any ideas ? I REALLY dont wanna give up my faster P4 mobo chip and ram. It's an urgent problem too coz he's moving to qld this sunday

Anyone got a spare AMD XP motherboard I can borrow or machine I can plug this thing into to test ?!

I've seen two things cause this

1) Hard drive is dying (yes, it may work with other mobo's/chips, I dunno, sometimes some mobos are more sensitive about dodgy drives). With most drives these days using SMART it's east to get a boot disk that checks and rules this problem out.

2) Mobo is freaking out. Look for bios updates, if that don't work, replace it.

could be the USB port driver?
maybe the generic driver used for that port disagrees with the chipset/mobo.
try upgrading the driver.

rty upgrading the cscamd20.sys file.

I doubt it's the HDD, its a 6 month old 80g seagate barracuda.

I'll check for bios updates. If I thought it was the usb component of the mobo (coz its a usb device) I'd buy a seperate usb 2 card (they're only about $40) I dont wanna buy all this stuff and be stuck with it tho.

No luck with any info on the sys file - not through google anyway.

Windows xp didn't autodetect the usb ports (there's 6 of em!. I installed the driver from the cd that comes with the motherboard. Will a generic driver be ok with them being usb 2.0 ?

i'd look up new mobo drivers, should come with new USB drivers...
though you'd think if the mobo is an AMD mobo the conflict would be elsewhere, like between the usb driver and windows...
check the manufacturer's website for updates,
or google it...

ive seen this error a few times with usb and win xp...
check your IRQ's for conflicts

also, something i read a while ago, do you have norton antivirus installed? if autoprotect is on, turn it off and test....

ive got some more things to try, ill post em up later im off home!

Well, theres been a vast improvement but I dont know if I've saved my motherboard and chip from repossession just yet

I flashed the bios with teh latest version and it seems to be much better. It captures reasonably well now (from a not dropping dead point of view!) but the resultant video is jerky. It claims no dropped frames but its pretty rough and doesnt seem to do it on mine (P4) Oh well, atleast the thing technically works now...
Still it seems like somethings choking or holding it back... I wouldnt have thought a P4 2.4 would be that far superior to an AMD 2100+

Have you installed the latest VIA 4in1 drivers? or video or other drivers etc...

IRQL*or 1*_LESS_THAN_OR_EQUAL_TO = CPU failure for some reason or another. Usually you'll get this error on an overheating CPU (Hello AMD), an OC'd CPU (which is overheating) or a stuffed CPU (not very often tho).

Try this:

1. See if there's a BIOS flash available for the MOBO and apply it
2. Fit the biggest, baddest heatsink & fan you can find. Forget about the "AMD Solution" and get something serious on it (Volcano anyone ?)
3. Download the latest drivers for the capture device for whatever version of Windows he's runnign (XP ?)
4. Download the latest MOBO drivers for the OS and apply them (Usually VIA or SIS)
5. Apply all the OS patches/updates/Service Packs you can find, even if they dont have anything to do with the issue you're having

If you hadda ask me a week ago I could have helped, just got rid of the one (and only) AMD machine I ever have, and ever will, own.

Anyway, trust me, I'm a professional .

I've always had intels but thought I'd give amd a go seeing as I saw a few good writeups on toms hardware guide etc. and they're a fair bit cheaper than intel. What turned out to be a $300 upgrade turned into a whole $1500 (by the time I get the monitor) new system

Is it likely that it is actually the cpu or could it be the motherboard instead ? I'm leaning towards blaming the mobo coz its cheap and atleast the chip was a packaged brand name one.

There's only one version of 4in1 drivers on the manufacturers website. I figured they'd be the same as thr ones supplies with the mobo but maybe not. They're 4.55 and there's a 4.57 at viaarena.com which I'll give a go.
I can't get any updated USB 2.0 drivers as they can't supply them due to some BS M$ licensing agreement. pft.
edit: I cant get any updated drivers for the capture thingy as it was only just released a few months back.
Thanks blackice and wrxcore.

not when you can o/c the 2100+ (assuming it's TredB core) to ridiculous clock speeds (mine runs at 190x13 (2.47G) fully stable (running prime for two days) ) not bad for a $170 cpu....
