Acer 5810TZG black screen *after* logging on Closed

Question

Hello, 

Apologies if this is not the correct section for this query...

I've spent the last day looking at forum posts related to the "black screen of death" on Acer machines, and while I have found some solutions for Acer Aspire One and others, I haven't found any that relate directly to my model, so I'm just hoping someone may be able to help.

Machine details:

Acer 5810TZG running Windows 7 Home Premium 64 Bit. I bought it less than 2 months ago.

My laptop shut itself down, I think as a result of a Windows Update. On restart it seemed to boot as normal, with the Acer/Windows screens, and then I logged on. The screen then went black despite the hard drive continuing to function. I could hear sounds from my desktop - e.g. Twitter replies coming in on Seesmic desktop client - but the screen remained black. I waited for a while but the display didn't come back.

After trying a few more times, and starting safe mode (which works fine), I did a system restore to a point before the most recent Windows update. On this occasion the machine booted up, I logged on, and I got to my desktop - hurrah! - but, after about 30 seconds, it disappeared again. Boo. The screen just went black despite the machine clearly still functioning.

I shut down the machine and unplugged it, and left it a few hours in case of overheating; I removed and reattached the battery; I've uninstalled a driver for a printer I installed a couple of weeks ago... but no luck. I'm still only able to use the machine in safe mode.

At no point were there any USB ports being used during this process (the printer I mentioned was in an office a couple of weeks ago).

Apologies for adding to the deluge of black screen posts already clogging up the internet, but I'm not sure what to do next. Do you think solutions for other models, like the Aspire One would be worth trying, e.g:

http://filetonic.com/...

Does this sound like a problem with a driver, or software, or the machine itself - since it appears not to be a hard drive/screen issue?

I haven't the best reports of Acer support so would prefer to avoid using my warranty if possible as I can't really afford to be without the machine for too long. But if there's no other way...

Any help most gratefully received!

ok try this 1  

when black screen is displayed then  
hold ctrl and shift keys and press esc key, task manager will be opened--->go to file-->new task --> type  
regedt32  
a registry editor will be opened and then follow the  steps  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon  

at the right side, find the strings shell & userinit and check the following  

shell value data should be  
Explorer.exe  

userinit value data should be  
C:\WINDOWS\system32\userinit.exe,  

If shell and userinit are having different data values then change it as mentioned above  

Just double click shell and userinit and enter the data values as  

shell value data should be  
Explorer.exe  

userinit value data should b  
C:\WINDOWS\system32\userinit.exe,  

Note: there is "," at the end of userinit.exe  


when you enter into  normal mode scan ur pc with antivirus &  

download malware anti-malware application-->update it -> then select  perform full scan and scan it
