Graphic card install hangs Vista after crcdisk.sys


dain waris

I have:
HP Pavilion m8013w
Athlon 64 X2 4800+ 2.5Ghz
ASUS M2N68-LA motherboard
ONBOARD GeForce 6150se
4GB Ram
Windows Vista Home Premium SP1

I have tried to install graphics cards in PCI-E:
Radeon HD 2400
Radeon HD 4850

I get BSOD on startup of Vista; Safemode shows last driver installed is
crcdisk.sys, then it hangs at that in safemode, or black screen in normal.

I can remove the graphics card, and it will start up properly.

At first I thought it was my ineffectiveness at disabling the onboard Nvidea
card, but tech support for those cards insist that disabling/uninstalling it
in device manager, and switching primary video adaptor settings in BIOS from
onboard to pci-e should be sufficient.

Googling the crcdisk.sys BSOD reveals this was a common problem when vista
came out with "incompatible" hardware on a Vista upgrade from XP, and is
either a hardware conflict, or conflict between drivers, but I could not find
a common solution.

My generalized hunch is that something with vista and the onboard card
doesn't like the new graphics card.

Does anyone have any thoughts on this, or a solution?

A guess:

Uninstall the drivers for your onboard graphics (nVidia) before installing a
discrete ATI graphics card. I have never owned a mainboard with onboard
graphics. I hope that there are graphics drivers (listed under the
"programs" control panel) as well as the nVidia chipset drivers.

Thanks, that's a thoughtful response, but one I've already attempted. In
fact, that is the prescribed method of installing the graphics card per the
manufacturer. I still get the blank screen on startup. I first thought that
my problem was being ineffective at disabling the onboard graphics beyond
disabling the nvidia driver and switching the bios to prefer the pci-e
slot--that is, some jumper on the motherboard, etc. But the manufacturer's
tech support says those should be sufficient.

Tech support stalled when we couldn't even get it to start up in safe mode,
hanging after cdcdisk.sys; it should start up with the default video drivers
with the nvidia drivers uninstalled, so that the new hardware can be
detected, and new drivers installed.

Perhaps it is those default video drivers which are conflicting with the new
hardware, in which case perhaps I should upgrade my bios?

Thanks again,

Sorry, the response wasn't particularly thoughtful.

The M2N68-LA board is, I see, an HP OEM version. I take it that HP support
wasn't helpful. What did they suggest? Clean installing the OS with the new
graphics card in place? (That might work, but it would take a lot of time.)

Another random suggestion: did you try clearing the CMOS? It appears that
the mainboard has a jumper for that. (I have found that helpful, when
changing graphics cards under Vista.)

I have had no trouble with the generic Vista X64 drivers for my graphics
card, but I have an Intel (P35) chipset.

Good luck.

Hi, Dain. I found this post from a couple of years ago. It exactly describes the situation I am having. I just spent yesterday reinstalling my OS and it still did not allow me to insert a new video card. (I tried two different cards with no luck.) Did you ever find out what the solution was? I have tried everything I can think of short of switching the jumpers around on the motherboard, including removing the battery to reset the CMOS. Any help would be greatly appreciated! -- frustrated in Maine.
