ah, finally i found this thread
well i do know norton antivirus, but as it sounds, all i know is that it was just another antivirus and doesn't have anything to do with my problem . anyway i'm trying to download the "free Norton 360™ Version 4.0 trial." at the moment, hope it will find something i really stressed out oh, and i would like to give some update in my problem about 3 days ago, i was cleaning up my room. and something crossed my mind that i should clean up my cpu case too, because you know, it's so dusty at times. so i removed the lid, take the motherboard and everything within, remove all of them and clean up individually, then put them back together. i even opened the PSU to sweep the dust from it. this time, i start up my computer WITHOUT the case (because i was kind of lazy to put them back in the case after all those cleaning up... ). and guess what? IT WORKED!!! i can even play dota without any buggy trouble for about one day... then it just fail again until now whatever i did and about the harddisk, i checked it with almisco's speedfan's (which is located in this link : http://www.almico.com/speedfan.php ) online hard disk test (or whatever it was called) and overall just like it said in the app itself, its overall performance is still rated "good" although the drive fitness has decreased. i was going to copy the result, but i was forgotten and left it in my pc, so maybe next time .____.' i hope this norton stuff could find something more so i can compare the result oh and one more thing i checked the event viewer in windows, and i found out this numerous error event ID 11 from "atapi", which is "The driver detected a controller error on \Device\Ide\IdePort0." i tried to move my disk to other port, and the error event will change the port numbers, so i guess it IS my disk fail or whatever this "controller error" means (since all device i have is in sata port) before i decided to replace my disk (which still not 100% sure and i'm kind of flat on bucks...) i want to re-check it again and decide it after showing you the results thanks for accompanying me
