[Senator Pardek]

Read through this thread concerning probs with dw.exe.

[Psycho_Bunny]

Did you Google it?

The second return had some interesting info....Error.

[PAR35]

You might try downloading Mozilla or Netscape and see if the problem repeats whey you use that browser only. If the problem doesn't appear, then you have a workaround.

Sounds serious. I would recommend one giant can of Whoop A$$ and call a computer salesperson in the morning.

Then again, I am a complete smart A$$ and it is highly recommended you ignore anything I say.

You didn't describe you computer configuration. Operating system, hardware etc. Any programs you have running and if you have a virus checker or not.

[I_saw_the_light]

Go here, Download this program and run a scan. If you have any spyware causing the problem, chances are this will take care of it.

Ok here is what I have been having problems with on my XP-Using Internet Explorer..just recently I have been getting a pop up that my whole screen will go white on me...then all of a sudden in the middle of the screen appears an enter button saying click here....once clicked it does tell me that my anti-virus system has failed and that I live in Alaska. (I use pcillin) It even replaced itself on my home page...this is the site that appeared on my home page (http://ad1zendmediacom/ad-spy) I have't had the problem for a few days as I have been going to file tool/internet options deleting cookies/ deleting internet files...even searched my computer to see if it was stuck somewhere...when this occurs I can only shut the computer down and reboot control/alt/delete will bring my bars back on the screen the besides the start button everything is inoperable...even though you can tell that my internet site are functioning behind this popup...any other suggestions where this puppy might be?

Heat can cause weird crashes too. Make sure you're getting good airflow from your power supply fan, then if it's good, check your cpu fan. This is best done with the case cover removed so you can look in. If it's spinning good, put your hand carefully in front of it for a few seconds, if you can feel a lot of heat (not airflow, but heat radiating from it) off of it you might want a better one. If there is very little airflow, or the fan is moving sluggishly or not at all, turn that machine OFF immediately and get it replaced! I've seen waaaaaay too many gremlins last through reinstalls, virus scans, and the like, only to be banished for good on replacement of a dying or dead cpu fan. If either of those are the cause, you can do the work yourself and save a bundle. A power supply (if that's the cause) is about $35, and maybe a 15 minute job to replace, less if it was assembled with any attention to where the power leads were ran. A cpu fan replacement is about $15 on average, for a good one, and takes about 10-15 minutes.

Not necessarily saying either of those are the cause, but if nothing seems to be wrong with the OS itself, and the problem persists after a reinstall, it could be worth looking into. In any case, checking your fans occasionally is good practice. Heat kills cpus faster than just about anything else, and can cause an amazing variety of problems at "sub-lethal" levels.
