A couple of helpful utilities that are free... These sites check clean & the files checked clean. I don't run sh*t without checking them first and you shouldn't either. I have run and checked these running under Windows 7 x64 on my system in my specs and have had no crashes or problems, yet. Hope not to have any, however, I have not explored every nook and cranny in all of these apps. First off, there is this diddy that will put your bios beep codes at your fingertips. It has been posted here before and it has been updated by Datum. Portable Beep Codes Viewer Spoiler Datum recently acquired Rizone, so, if you are familiar with Rizone software then you notice that you will be redirected to Datum now. Rizone, also, had a piece of software called Rizone Internet Repair, which, is not on the Datum site, as of yet, but can still be had at the likes of CNET. Spoiler Second, we have WELT (Windows Error Lookup Tool) from Gunners' Software. Quote from there site: Spoiler These two tools/utilities I found to be of possible use in troubleshooting, along with other sources on the web. There are others that are as good or maybe better, either way, if you find 'em - share 'em. Post any others you know of. I like trying good software... especially free or free to use! EDIT 5/28/2012: UPDATED WELT (Windows Error Lookup Tool) to version 3.0.5 And, Datum (prev. Rizone) has updated and added the free to use, portable, and useful tool to their website > Complete Internet Repair Version:22.214.171.1245 Updated 5/27/2012 Complete Internet Repair is a portable troubleshooting tool that can fix many common Windows networking and internet-related issues. Spoiler And, for you people using firefox and having a large chuck of memory being taken by so-called, memory leaks... (Now, I say so-called, because, I have read about it, but, I do not use firefox, so I can't speak to it); you can try Firemin. Firemin download page Spoiler Here is a nice web site, if, you ever need to find a default router password > RouterPasswords.com Edit: Added from Frick.
