ROM questions

[jeephed]

Hey guys, I'm kind of at a loss here. I'm having a lot of weird problems with the phone all of a sudden and it dowsn't seem to matter even if I hard reset or not. I'm on the stock ROM (Verizon) with windows 6.5. I can't get any 1% program to load and work, and now my slider won't make any sound.
I downloaded Mighty ROM, Mr. X Rom, and the stock ROM. I tried to install the Mighty ROM and it won't go past 0% and then errors out on me. Not sure what to do here. Any ideas are greatly appreacated.
Thanks guys
