Ok so ever since I bought my Radeon 6570 I had this problem where if would restart my computer my games would become really laggy. I found out that it was drivers. I would simply redownload the driver and it would fix it. Well a couple of days ago I used the AMD autodetect to find my driver and it downloaded it. Well I restarted my computer and I have the same problem but this time I can't redownload the driver because it says I already have the current driver.
