My acer laptop (acer aspire 5745DG 3D) recently got really slow and laggy. What was more strange is that in task manager it showed 0-9% CPU usage. Then there were more stages that lead it to go wrong.
Anyway, i have removed the hard drive (Western digital blue) and saved all my important data to a separate desktop PC (using a separate cable etc).I have reinstalled windows (7 Ultimate 64bit) on that hard drive using the PC then putting it back in the laptop, but the same problem remains. When i boot windows from the hard drive on the desktop PC the same thing happens (it hangs, goes black and restarts). The warranty for the laptop has expired just a few weeks before it started going wrong and acer support is no use.
My brother, who is quite good with computers, says that i may need to buy a new hard drive but before i do, i thought i might ask you guys.
Thanks for any help or suggestions.
