Computer not working. Blue screen (BSOD) at startup?

Question

I have a Laptop - Acer Aspire 5732ZG with Windows 7 64 bit OS. I bought it 3 years ago.

When I turn the laptop on, after "Starting Windows" I get a blue screen with this message:
"STOP: C0000135 The program can't start because %hs is missing. Try
reinstalling the program to fix this problem."

The computer reboots and goes to Windows Error Recovery
- 2 options I get- Launch start up repair
- Start windows normally (this option takes me back to blue screen then reboots and back to Windows Error Recovery)

SYSTEM RECOVERY OPTIONS
--------------------------------------------------------------
START UP REPAIR
The message I keep getting is

SYSTEM RESTORE
- Description = Windows Update. Type = Critical Update

WINDOWS MEMORY DIAGNOSTICS
- Restart now and check for problems -
after scan - restarts and back to blue screen after "Starting Windows" and back to "Windows Error Recovery"

COMMAND PROMPT
- This is an area I really know nothing about. I have tried the following but to know avail.

Code Entered- "bootsect.exe/nt60 SYS/force" then I am prompted to enter "bootsect /nt52 E:" which gives message:
"succesfully updated NTFS filesystem bootcode. Bootcode was successfully updated on all targeted volumes" then I type in "exit" and restart
Code Entered- "bootsect.exe/nt60 ALL/force" then I am prompted to enter "bootsect /nt52 E:" which gives message:
"succesfully updated NTFS filesystem bootcode. Bootcode was successfully updated on all targeted volumes" then I type in "exit" and restart

RECOVERY MANAGEMENT

Completely Restore System to Factory Defaults

Other information
- The last time the computer was working, Windows performed an update when I shutdown the computer
- I've been running a free version of Avast (anti virus software)
- I don't have a Windows 7 recovery disk
- I have had the blue screen error before. But miraculously Startup Repair must have recovered the error as it worked on the next restart.
I have tried Startup Repair at least 20 times hoping for a miracle but this time I've run out of luck.

If anyone knows of other things I could try please reply. Thankyou.

Answer 1

You might try safe mode with the command prompt or what ever gets you the command prompt. When you see the C:\, type in "help" and it should give you a list of available programs. Look for "chkdsk". With any of the listed programs, you can type in the program, a space and "help" and you should get some instruction on what it does.



If you cannot figure it out, Acer Aspire most likely will send you a replacement disk if you contact them and supply the serial number of the oporating system as Win7 is still an active product.

Answer 2

The following answer is from the Lexington computer blog





I have noticed that this consrv.dll virus is back again this week. It also seems to have some friends, make sure you do a scan with TDSSKiller and, once you’re up and running, that your Base Filter Engine Service, Windows Firewall Service and Security Center Service are running. If they aren’t, take a look at my blog entry on fixing a missing BFE in Windows 7. Also, if you are clueless on how to edit the registry from the recovery console, take a look at Web Traffic’s post from 4 Dec 2011 or Nick’s comments below from 20 Jan and my comment from 24 Jan 2012, this may help (and remember to unload the hive when you are finished with the edit).



This was a Windows 7 machine that had caught a virus. The virus was removed while the drive was out of the machine but upon subsequent boot to either safe mode or normal mode, the blue screen error “STOP: C0000135 The program can’t start because %hs is missing. Try resintalling the program” would appear. No error logs and no help on The Google (the computer does not have AVG installed).



The fix for this problem requires a registry edit to remove a reference to the consrv.dll file that was a virus and was removed. Using regedit from the repair console, the following keys required editting:



HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\SubSystems



HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Session Manager\SubSystems



Under theses keys, edit the data in the Value Name “Windows”, changing the text “consrv” to “winsrv”. This is a long string so just parse through it and make the one change, here is what a good entry looks like:



%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,20480,768 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ServerDll=sxssrv,4 ProfileControl=Off MaxRequestThreads=16



I have bolded the entry that previously said “consrv”.



Alas, there are apparently (many?) other reasons for this error, if this doesn’t fix yours, you may want to give up early and reinstall because there do not appear to be any other solutions out there.

Try to reinstall window because it's a last option
