I’ve got black screen and a blinking cursor with an error “The instruction at 0x73add9a5 referenced memory.”

Please read the whole message before you reply. I’ve been searching on Google for the past five hours seeking for an answer but no one are assisting at all. I used a Compaq Presario CQ61 running Windows Vista Home Premium OS. I used to download TV series/movies & songs. And this morning I was downloading a series of “Lie to Me” after I left home, I came back and the laptop had turn off because the battery was empty. And then I turned it on. It performed nothing. After I tried to log in, I just saw a black screen with a cursor.

After that, I have opened the task manager a lot of times, and it shows an egg timer cursor and does nothing. I have also tried the command prompt under safe mode operation but it didn’t run. Nothing is functioning AT ALL. I made a diagnostic restart; I found an error message when it restarted:

explorer.exe - Application Error

The instruction at 0x73add9a5 referenced memory at 0x73add9a5. The required data was not placed into memory because of an I/O error status of 0x0000185. Click OK to terminate the program.

Also, I was searching Google for this error but nothing looks to be related. Please help. I can wipe the hard disk of my computer but do not want to drop all my music & pictures. Thank you so much.

Hi! Try these:

  1. Open up your command prompt, type chkdsk /r and press Enter. The /r attempts to retrieve any bad sectors found by chkdsk. However, any data on these bad sectors, you can never recover anymore.
  2. Run Windows Memory Diagnostics. For more information about that, please go to this link: http://windows.microsoft.com/en-us/windows/what-are-system-recovery-options
  3. If the above doesn't work, try a system restore. The above link will also give you steps on how to do a system restore. A system restore will restore your pc to a point before you got the error.

I hope all the above helps. Cheers!

I encounter this problem a lot. I mean the error “The instruction at 0x73add9a5 referenced memory at 0x73add9a5 …” This error is normally not serious like in my case. I usually encounter this problem when my computer is still loading and then I suddenly shut it down forcing the programs to immediately kill their process and then that error appears then the computer shuts down.

But when I usually turn it back on the system is normal. I think in your case it is different because the computer shuts down due to low battery while downloading something from the web. It seems the previous unfinished task caused a major damage to your system files. When a computer untimely shuts down while files are still open may cause serious problem to your system.

There are times the open files will be instantly deleted and sometimes will become corrupted. Since you can still start your computer in Safe Mode, the last option you can do before you end up formatting it is to start it using the last known good configuration. To do this, restart your computer again.

Press F8 before the Windows logo appears. When the Windows Advanced Options Menu appears, use the arrow keys to navigate to the options and then select “Last Known Good Configuration (your most recent settings that worked)”. Press Enter twice to boot the computer and then see if this setting works.
