My touchscreen won't work. I've rooted my phone for a good year now and i've hopped through everything from CM to BB to Sapphire to everything.

I recently installed Pete's new stock 2.3.3 rom and my phone started going crazy. It would take a long time to do load up from stand by and it would freeze and crash. Now the touchscreen wont work and i've unrooted my phone to see if it would work but nope. So any help?
