I built my computer last June and around 4 months ago, my HDD started acting up. Every time I start up my computer, open an program or game, or sometimes even just while sitting idle, my disk usage will spike to 100%. When checking task manager, most of the programs that are supposedly using alot of disk usage are at most using 1.5 mb/s. Usually, the task titled "system" is at the top and using the most usage. While my disk usage is at 100%, my computer will slow down and lock up. It has even crashed a few times and after automatically rebooting, my hard drive is not listed in the BIOS. I have to do a complete restart to get my hard drive to appear in the BIOS. I have used a couple programs like HD tune pro and Data Lifeguard to check my hard drive, and none of them say that there are any problems. I am unsure if this is purely a problem with my hard drive or if there is a problem with something else, like my operating system. Please let me know if there is anything that I should do or check.
