Specs: Windows XP, P4/1 gig
I have 4 Dell Optiplex 745 that are freezing up at random times. Some times the computers will run for an hour before they freeze up and some times they freeze on start up.

sounds to me that all need opened up and cleaned out with compressed air which can be purchased at any office depot or office supply store.do not use a vacumm cleaner as these can have static elcetricity and screw things up.sounds like a good cleaning will do be sure and check processer fan which is probably clogged causing unit to overheat

Cleaning out dust is always a goof thing (part of annual maintenance), but if it does this at start up it is probably something else. You can install Speedfan or similar program and monitor your internal temperatures to see if it is heat related and verify if this is needed to solve the problem. I do believe that your problem is a bad memory stick or possibly other hardware issue. To check your memory use Memtest86 and run the full set of tests, or until you get errors. If you get any errors you will need to replace the memory, but you can rerun it with one stick at a time to find the bad one, though if you are using dual channel memory you should replace them as a pair. Post back results.

You have to be a little bit crazy to keep you from going insane.

I have cleaned out the computer with compressed air, swapped the memory, hard drive and power supply with out any luck. If the computer sits idle, it will stay on for quite awhile, but as soon as I try to open a program, it freezes up.
