i have an aspire 5755-6832 that is experiencing extremely slow performance at times. the hard drive LED lights up and stays on for anywhere from a half hour to an hour. perf-mon doesnt show a lot of traffic on the drive at these times but the machine is pretty much un-useable until the drive activity drops to 0, then its ok for a while. i have a recent backup so i decided to use the recovery DvDs and replace the C: partition. after doing that i ran a disk check, then after that i ran a defrag to see what kind of performance i would get. with a fresh install of the OS and the drive 1% fragmented, the defrag took over an hour.
today while installing some software the computer is still going into spasms randomly where it lags to the point of not being able to use the keyboard, resize windows, etc...
i'm out of warranty with this machine and i will probably throw a solid state hard drive in if it is indeed the drive that is failing. before doing that i want to make sure that it isnt an I/O controller problem, or other mainboard problem.
any hints?
