I have a noisy second story floor that crunches(it does not squeek) when walked on. I believe it is from the particle board sub flooring. I have tried screws and nails with no relief. Should I pull up the sub floor and start over?

Details, people, details....we must know more of existing conditions. How old? What is the finished flooring? Do you know how it was installed? What is accessable? The more info you provide the better your chances of recieving responses that can be of help.

O.K. Here's some more info. .... The house was built in 1979. The room is on the second floor. I pulled the carpet up and the flooring is 1/2 inch particle board. My thought was to remove the particle board and replace with plywood, securing with screws and construction adhesive.
Smokey, the problem can be comming from several areas. Balloon framing, undersized floor joists, no shear wall, etc. You could try pulling up the sub floor and replacing it with 5/8 OSB but thats still no guarantee. I think you need to tell us a little more about you home construction before we can offer any legitimate advice. In my case, I went on a diet and lost 40 lbs. On the downside of that remedy, I loose a lot more bar fights now. On the upside, the wife doesn't hear me when I sneak in late at night. O.K. its only 7:30pm but its late to me!
Save the trouble of pulling it up and drill holes through the PB but not subfloor. Use a glue syringe to inject glue. Then send a screw into the same hole. Cost? 20-30 bucks and labor.

First off I never saw a particle board floor. Was it installed by the builder or homeowner down the line? If it was the builder then your probably in a bit of a pickle cause.....how cheap can ya get? If it were me...I'd pull it up. Inspect the floor joists and it theyre sized properly I'd screw and glue down plywood. But thats just me and whatta I know??? Piff idea of Gorilla glue could cause issues if it doesnt work....Like THEN trying to pull it up.
7:30 to go to sleep? Who said that? LOL
Be well

PB unde5rlayment was pretty standard for under lino or carpet for a lot of years, Andy. If you did decide it doesn't work and want to pull it up, you back the screws out and jerk it up. It is gonna break up easy for demo anyway and then a scraper will take up the shreds left in the glue spots every eight or twelve inches.

It may be undersized floor joist that are moving.
It sounds to me like you have a situation where there is a subfloor and a wood floor or underlayment that was installed with no adhesive or paper cushion between. The two layers of wood are slapping together.
IF
that's what it is, you could try to find a way to drill small holes and inject gorilla glue between. Then stand back!
