This only started happening about 4 days ago, and i don't know why, i have checked to see if java, adobe, and my browsers were updated and they all are. What happens is, when i watch a video, if i click ANYWHERE on that page, the video rewinds, and keeps doing it no matter what. I can't skip to where i was in the video, or anything, the play button won't even change! And when i go to try and clear the cache or cookies, the computer just scrolls through all o the options at, and keeps doing it, and i can't stop it, and it does it so quickly, i can't clear the cache. Even when i try to move a sticky not on my desktop, the computer freaks out and everything shake and moves and glitches to somewhere else on that page. I should mention that sometimes when i start up my computer, apparently it make a loud beeping noise (kinda like the "ALERT" sound on an iphone) i want to know if this is something i can fix by changing one thing with my computer, or if its something different. I've had my computer for 6 years now (on the outside its in great shape)
