Hey there guys, about six months ago I started receiving an error every few days on my computer on boot, and it was something along the lines of: 'pxe-rom: Check cable connection!'. To fix it I just used my Windows 7 install CD and it was fine, until whenever it'd happen again. Now, just about three days ago an error popped up that said 'Windows has detected a hard disk problem'. The hard drive is a 640 GB Toshiba MK6465GSXN. Anyway, after getting that message I quickly backed up all of my important documents and stuff onto an external HDD. It was also very slow, slower than my computer had ever been. So, I decided to do a clean install since scans with Malwarebytes and AVG detected nothing. And then, once it finished, it popped up the error message again?! I have noticed that the slowness has gone, but I'm not installing any programs in case it does fail. I am wondering that maybe the 'check cable connection' error was telling me something, but I didn't think anything of it. So, does it sound like I need to get a new hard drive?
EDIT: I bought a new hard drive, fixed!
