So starting about a week and a half ago my computer has been acting weird. First it started having booting failures and after a couple windows launch repairs it would boot normally. This has happened about 4 times. Then last night I start my computer and I notice my hdd light is staying constantly lit and my system is slllooooooowwwwww. I use windows error check and says hard drive is fine. I unplug any peripherals I can and reboot; then comes a launch failure. After about a half hour of cycling launch repairs it boots and I run an error check while also checking for bad sectors. At this point it was really late and the check was going to take a while so I went to bed. Come down this morning and turn it on and now it's performing normally but I didn't get to see the results of the check. Does this sound like the beginning of a hard drive failure?
