ATAPI.SYS BSOD 0x0000007A & 7E

I leave my computer on all the time, when I get home from work (so far this
happened twice), I get the following:

KERNEL_DATA_INPAGE_ERROR

0x0000007A (0xC05CF790, 0xC000000E, 0xB9EF2384, 0x270E3860)

ATAPI.SYS B9EF234 BASE AT B9EE500 DATESTAMP 41107B4D

---- And after I reboot, it does this perpetually, until I finally clicked
on "Last Known Good Config"

0x0000007E (0XC0000005, 0XB9839184, X0BA506D44, 0XBA506A40)

I already tested the RAM (2 GB DDR2 800, 1x2dimms)
The Hard drive has no physical errors.

I had Daemon Tools installed. I uninstalled it after this happened (Virtual
CD/DVD ROM Drive)

I have a Conroe E6700 2.66 GHz Core 2 DUo
Intel DG965WH motherboard with latest bios version

I also have a Hauppauge TV Tuner, PCIe x16 Graphics Card and Creative Sound
Blaster Audigy 4

Any ideas? What's going on? I just spent $1500 and am CLUELESS! :(

Thank you in advance!

I recently experienced a similar problem. As it turned out,
my video card was not fully seated in the motherboard slot.
I would recommend carefully removing each piece of hardware
from it motherboard slot, then reinstall, making sure it is
fully engaged in its respective motherboard slot. Also, make
sure all electrical connections are secure and no wires are
touching the RAM modules.

I already reinserted the cards. I don't believe there are any wires over the
RAM, but if there was, and I can't move them away why would that cause a
problem? I ran Memtest 86+, for 8 hours, not one error....

Thanks for the quick response, I really appreciate it.

Some types of malware camouflage themselves as atapi.sys, particularly if
they are located in c:\windows or c:\windows\system32 folder. Thus check
the atapi.sys process on your pc whether it is pest.
Download and run Security Task Manager for verifying your computer's security.

Also, check for unsigned drivers:

I already ran SFC... and checked the date of the file, it's in 2004 it'ws
original, what would explain the other stop error im getting?

I dont have any malware on the PC, it's freshly formatted, and new and I
just built it.

If I have any unsigned drivers and the vendor does not have any signed
drivers, what do i do? And how do I solve the problem??

If possible, I would like *ALL* possibilities for the cause of these stop
errors... I do APPRECIATE everything you have replied with... I want to get
this resolved asap... and want to try everything you tell me.... Instead of
just replying back and forth, I'd just like to know every single possibility
so I can try them all. Thanks!!!

Troubleshooting Stop Error Messages

i looked at those stop error sites... none of those help me at all..... as of
now i will reseat all cards and check for unsigned drivers.. but what else
can i do? those websites about stop errors wont help me.. they only specify
specific situations that dont appy to me.

What is the rated wattage of your power supply unit?
Sometimes an over-taxed PCU can cause error messages.

500 watts.... that ok ?

Are you seeking help or offering advice?

also you might have a nasty program called securom on your pc it caused my pc to crash all the time untill i reinstalled windows

[Blu Bit]

I had the exact same problem with an Acer Aspire 5100 with XPx86 (32-bit) SP3.
At first the machine wouldn't even boot up and the guys from a computer repair shop said the motherboard is fried.
I was able to start from a linux usb stick and reformatted the entire disk.
XP was reinstalled, but this time round BSOD's would appear claiming kernel_inpage_error or atapi.sys fatal error blabla...
I noticed that the "r" on the keyboard didn't work so for the fun of it I took the keyboard out to see if there were any obvious damages.
Supposedly it was a faulty contact in the keyboard generating invalid IRQ's or some internal bus conflict of that nature.

However, long story short message: Disk errors can be related to faulty hardware. Strip the machine to a minimum and observe if the error persists.

KERNEL_STACK_INPAGE_ERROR
Error: 0x0000007A
Parameters: 0xC000000E 0xC000000E 0x00000000 0x016C5000

Fou guys are quite a cool group... constructive advise and good references.

The error has disappeared since I extracted the keyboard.
It has not crashed on me for about 5 days and I'm using a usb keyboard.

Unfortunately the HDD make is toshiba and they dont provide any tools.
I tried using SMART monitors and CHKDSK but they didn't report anything.

Thanks for the help anyway.

Post the complete error message as shown including all the error numbers associated
with it

Can you confirm the first parameter is correct as to see 0xC000000E as a
first parameter is normally seen with an STOP: 0x00000077 (0xC000000E,
0xC000000E, 0x00000000, ??????????). You can often see 0x0000007A and
0x00000077 errors on the same computer.

0xC000000E
STATUS_NO_SUCH_DEVICE
A device that does not exist was specified.

0xC000000E, or STATUS_NO_SUCH_DEVICE: the drive went unavailable,
possibly a bad hard drive, disk array, and/or controller card.

Is this an intermittent error or does the computer never boot?

What is the hard drive make and model? Have you tested the hard drive
with the manufacturers test utility?

Background information on Stop Error message

0x0000007A: KERNEL_DATA_INPAGE_ERROR
A page of kernel data was not found in the pagefile and could not be
read into memory. This might be due to incompatible disk or controller
drivers, firmware, or hardware.

I suspect this is the type of problem where chkdsk will not help.

You might find a clue in the System log of Event Viewer. However, this
type of error can be before Event Viewer logging starts.

You can access Event Viewer by selecting Start, Control Panel,
Administrative Tools, and Event Viewer. When researching the meaning
of the error, information regarding Event ID, Source and Description
are important.

A tip for posting copies of Error Reports! Run Event Viewer and double
click on the error you want to copy. In the window, which appears is a
button resembling two pages. Click the button and close Event
Viewer.Now start your message (email) and do a paste into the body of
the message. Make sure this is the first paste after exiting from
Event Viewer.

problems.

Download and run it and see what it turns up. You want HD Tune
