Still waiting for some help on my system crashing.  Can anyone see anything wrong with the log or have a suggestion as to what may be wrong?

I don't see anything in your log but there is a new infection that is HijackThis aware and hides when it sees Hijackthis coming.  Right click on the Hijackthis.exe file and Rename it from hijackthis.exe to hjt.exe. (you may not see the .exe part in which case just change it from hijackthis to hjt).

 

Then run it again and let's see the new log.  We should see a new entry appear in the O20 area if it's that infection.

Blacklight Rootkit Detector:

 

Download Blacklight trial from here: http://www.f-secure.com/blacklight/

Hit "I accept." It will take you to the download page. Download blbeta.exe and save it to the Desktop. Once saved... double click blbeta.exe (you may not be able to see the .exe) to install the program. Click Accept Agreement and click Scan This app may trigger a warning from your antivirus. Let the driver load. Wait for it to finish. If it displays any items...don't do anything with them yet. Just hit exit (close) It will drop a log on Desktop that starts with fsbl....big number

Please post contents of log in your next reply.

 

A Disk Check:

Run a disk error check and see if your harddrive has problems.  Start, My Computer then right click on Local Drive C and select Properties (verify that it shows you have at least 15% free) then Tools, Error-Checking => Check Now.  Check the 2 boxes then Start.  It will tell you it can't do it now but will be glad to schedule it for your next boot.  Tell it OK. When you reboot it will check your drive which usually takes 30-60 minutes.  Sometimes it will even fix your problems while it is at it.

 

Memory Check:

Verify that you still have the same amount of memory as you did originally.  (Start) then Open My Computer and select Help then about Windows.  Is the physical memory about what you bought?  Sometimes a single chip will fail and drop your memory in half.

 

Run a memory test.

When it is running slow:  rightclick on the clock and select Task Manager then select Processes.  Click once or twice on the CPU column heading until you get the numbers at the top in that column.  What are the top three processes and what % do they each take.

 

Check the Event logs for errors:

Start, Run, eventvwr.msc, OK then select System.  Look for red marked files that have a time stamp about the time of the slowdown.  Open the event then click on the bottom of the three buttons to copy the text.  Move to a reply and Edit, Paste.  Repeat for any other different errors that happened during the last slowdown period or last reboot.  Please don't go back to the beginning of time and no events from a Safe Mode boot.  Repeat for Application.  If your PC speaks something other than English don't translate it unless it doesn't use the Latin alphabet and then please include the timestamps.

 

Check the Device Manager for problems:

 

(Start) then rightclick on My Computer and select Manage.  Then Device Driver.  click on each of the + marks to open each item.  Look for red marked items and uninstall them or delete them and reboot.  Do they come back with red marks?

 

Check for a bad file in System32:

Start, Run, sigverif, OK then press Start and wait for the program to finish.  When it finishes sort the output by date by clicking on the Modified column header once or twice.  Look for files with .exe, .dll or ,sys extensions that were modified about the time the problem started.

 

Check for a bad program:

Start Run, msconfig, OK

Go to Services tab and click on the box to hide Microsoft Services then uncheck everything that remains.  Go to Startup tab and uncheck everything.  OK and reboot.  If it doesn't run faster then go back into msconfig and recheck the things you turned off.  If it helps then go back and turn on a few items each time until you find the culprit.\
