White screen after Windows 7 update


Recommended Posts

There are only two things that changed recently on my Toshiba laptop (that I can think of). One is that I either installed or updated Java to run a particular webpage. The other is that Windows 7 did it's update thing, and ever since that, starting with the reboot after it finished, I get a white screen after logging in to Windows. Ctrl-alt-del works, but Task Manager doesn't show when I try to run it. The only way I've been able to do anything with the computer is by booting to safe mode w/ command prompt. From there I've been able to get one of those logs I've seen people post here and run a non-updated version of MWB, which didn't find anything (not surprisingly). I only know just enough when it comes to computing to know that I need some help on this one. Any given would be much appreciated!

Welcome to the forum, can you do this in safe mode:

Please download Farbar Recovery Scan Tool and save it to a folder. (use correct version for your system.....Which system am I using?)

Please make sure you click download buttons that look like this, not "sponsored ad links":

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

Lets try this:

OK, here you go......this should get you going:

Please download the attached fixlist.txt and copy it to your flashdrive.

NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system

On Vista or Windows 7: Now please enter System Recovery Options. (as you did before)

Run FRST64 or FRST (which ever one you're using) and press the Fix button just once and wait.

The tool will make a log on the flashdrive (Fixlog.txt) please post it to your reply.

See if the computer boots normally now and if so..........run MBAR

If not...rescan with FRST and post the new log

Download Malwarebytes Anti-Rootkit from HERE

  • Unzip the contents to a folder in a convenient location.
  • Open the folder where the contents were unzipped and run mbar.exe
  • Follow the instructions in the wizard to update and allow the program to scan your computer for threats.
  • Click on the Cleanup button to remove any threats and reboot if prompted to do so.
  • Wait while the system shuts down and the cleanup process is performed.
  • Perform another scan with Malwarebytes Anti-Rootkit to verify that no threats remain. If they do, then click Cleanup once more and repeat the process.
  • When done, please post the two logs produced they will be in the MBAR folder..... mbar-log.txt and system-log.txt
To attach a log if needed:

Note:

If no additional threats were found, verify that your system is now running normally, making sure that the following items are functional:

Internet access

Windows Update

Windows Firewall

If there are additional problems with your system, such as any of those listed above or other system issues, then run the fixdamage tool included with Malwarebytes Anti-Rootkit and reboot. It's located in the Plugins folder which is in the MBAR folder.

Just run fixdamage.exe.

Verify that they are now functioning normally.

The white screen came up after logging in again, as it did before. However, I was able to interrupt the shutdown process which gave me access to the desktop and my flash drive, and have since run mbam which found 2 Trojans, and I am currently running mbar to make sure it's clean. Once that finishes up, I'll attach whatever logs I've got in another reply. Thanks again for taking the time to help walk me through this stuff!
