well there probably all going to fail
uninstall all AMD drivers then run this tool
http://downloads.guru3d.com/downloadget.php?id=1275&file=4&evp=7b9d6ae343b65b8df84cc27ec59796f5

this removes anything left over by AMD
Restart and run 13.1 install again and all should work

most use btc-e as a low and bitstamp as a high and go half way between.

i belive it has happend once and only once so far. im not sure if it was true or not but there where threads about it some time ago.. anyhow if you generated 1000 bitcoin addresses a second for a million years i think it works out at a 50% chance so yeh not very likely

btcchina is one of the main forces driving the boom in bitcoin because there buying so many. i doubt theres going to be a crash today and i belive bitcoin could pass 1000 before it even slows down

bitcoins only get lost if there are alot and i mean alot of transactions in a small amount of time with no network fees. this is why most clients automatically add a fee to any transfer. iv never heard of it happening on a transfer from 1 person to lets say 10 people with no fees this just takes a long time.

but bitcoins go to an exchange and convert them
 or for litecoins go to

for speed

for a cheaper deal on here

pool. 4200Kh use to be alot put its hardly anything theses days on litecoin i think the network hash is close to 1Gh or just above on ltc so 4Mh isnt going to make much on solo

after 5 hours logged in and 10 posts no time limits at all

to most newbies this is what you call and ASSHOLE.. probably not true and all a figment of some stupid attention seeking asshole..

also filed the post for deletion your welcome

have you tried restoring the back up to a local wallet "bitcoin-qt" trying your passwords on that

also make sure your keyboard layout is the same as before. if its a new install most defaults are US keyboard and if your UK the " and @ change places its can be a bitch at the best of times

get out of newb jail and pm friedcat
iv never seen the code hanging around but, been as theres no cheap knock of versions i assume the code isnt public

the pool calculates it on how many shares you submit and how many are accepted

easy miner i think counts all shares both rejected and accepted
it could be down to a bad internet connection with a high ping
but more likely its lack of cooling causing the chips to overheat a throttle back
make sure theres room around the miner and that its got good airflow
then if it still happens try disconecting the miner and letting it cool so the case is cold then plug it back in and see if its back to normal
if that dosnt work use a newer version of cgminer id recommend 3.5

check all the connections. sometimes if the blade isnt sat just right in the back plate it wont get power. also try other slots. this is the problem with new people using 2nd hand hardware. it will either be something stupidly simple such as a bad bad connection or something really complx such as a bad blade or PSU

to transfer bitcoins out of mtgox you need to have a verified account. this means sending them id and such.

try using firefox or google chrome.

also added a link on mega
version 3.5
https://mega.co.nz/#!qI8ykIRL!DBySNnqaoHHgnRmuFBSAaWCVp2oWfwzW2IUp02qxWaA

both are good sites i personally use btc-e more

if its got a long secure password then no its not easy to hack aslong as its random and not just a bunch of words
the only exception is if you have a backup of the wallet before it was encrypted. that backup would still be unencrypted

is your wallet synced with the network? payments are made a few times a day

try them 1 at a time. sounds like there not getting enough power
