Looking for a self booting diagnostic app any ideas?

To diagnose what? All harddrive makers put out a bootable diagnostic. Other vendors have diagnostics for ram problems but if you want a bootable windows diagnostic to test for software problems then there isn't a one-size-fits-all app that will do it. I used to have a signature but it disappeared and I just couldn't be bothered writing another so please feel free to ingore this.

Download the Ultimate Boot CD http://www.ultimatebootcd.com/

Running a memory tester does a good job of checking all the hardware except the drives. Memtest has an ISO for creating a CD http://memtest86.com/ Do yourself a favor BACKUP! Sorry, I do not check for private messages

Like Richard59 said, to diagnose what? "If it ain't broke, upgrade anyway."

I've had the Ulimate Boot CD laying around for a couple of years & never used it. I had a problem recently & heropsycho2177 (who usually posts in the gaming fourm) recommended I try it. Since my copy was older, I went to the website & downloaded the latest version. The number of useable diagnostic programs included on the CD are amazing! Memtest & DocMemory are just two of the many programs on the disk. I wish I would have began using it a LONG time ago...it's "one stop shopping" for diagnostics. Check out the site & have a look at what's included.

yea i was pretty much just looking for an all in one tool, its been so long since i worked on a tech bench i had forgotten all the appz i once used. thanks for the help guys
