c0000005 The instruction at 0x%081x ... Error Fix?

Hi all,

A colleague at work is getting a blue screen whenever he boots Windows 7 Professional 64-bit.

Can't access safe mode, but ~can~ access the recovery console.

The full error reads:

c0000005 The instruction at 0x%081x referenced memory at 0x%081. The memory could not be %s.

There is no other writing on the blue screen other than that.

The crash occurs immediately after the windows logo is done glowing a little.


Things I've tried:

- Run /chkdsk /r from the Windows CD recovery console.
- Run /fixmbr from the Windows CD recovery console.
- Run /fixboot from the Windows CD recovery console.
- Run /rebuildbcd from the Windows CD recovery console.
- Boot the HDD from another (known working) PC. The same thing happens.
- When the HDD is in the (known working) PC, I can access all the files on it absolutely fine, so the drive appears to be in good shape.
- Run the HDD support utility from the manufacturer, did all scans. Nothing to report. Seems to be in good health.

After reading through:

I have been advised to use:

To see what is causing the buffer overrun during the blue screen... The only problem with that is, I can't install it as windows won't run...

Does anyone have any ideas?

Or does anyone know how I can get the Debugging software installed and running on a hard drive that won't boot into windows at all?


Thanks in advance! :)

i have a feeling it is a problem with the windows installation itself cause you said that it is failing to boot past the logo.. although i've never encountered this problem myself i think the best bet is the reinstall windows seeing how you can't get into safe mode :/

it could be a faulty or unseated memory stick if there are multiple stick.

try using one stick and see if it boots.

Hi, 0xC0000005 app error it is Memory Access Violation.
Some process is trying to read from or to write into not allowed memory area.
That may be error in some recently installed application, some updates or drivers.
Also, that may be some virus.
Check for something that.
Good luck!

There's no problem with the RAM. The PC works fine with other hard drives.

@NH123 - Yeah, I looked up the error code... Any idea how I can track down which process it is causing the error?
