My setup:
OS:PCLinuxOS & Windows XP - use mainly Linux
Motherboard: Intel DQ965DF
CPU: Dual Core @ 2.8Ghz
RAM: 3.5GB Kingston DDR2
GPU: 512MB Nvidia Geforce 8800 GT
HDD: Western Digital Caviar Blue WD2500AAJS 250GB 7200 RPM SATA 3.0Gb/s 3.5" Internal
My problem:
My computer became suddenly sluggish a couple days ago out of the blue. Programs are slow to load, scrolling with the mouse is jerky, videos pause then continue 5-30 seconds later, downloading(any protocol) brings my PC to a standstill, etc. I have this problem on both Linux and Windows, so I know it's not a software problem. Additionally, I've had unexplainable data loss. Files that used to be there(on my Linux /home partition) have suddenly disappeared without a trace.
I've tried the following so far: I've cleaned my computer of all dust and dirt. I've switched to onboard graphics(intel). I disabled 3D desktop effects.
Both operating systems are fully up to date, including drivers. The xorg.conf file for my Linux OS is correct. Since software, dirt, my graphics card, and 3d acceleration don't seem to be the problem I've moved on to my hard drive. I decide to use
smartctl in Linux to analyze my hard drive, however, I'm not sure what to make of the output.
Checking to see if my hdd supports S.M.A.R.T. technology:

ERROR: smartctl requires a device name as the final command-line argument.
Use smartctl -h to get a usage summary
...but for some reason it wouldn't let me.
I also ran the
Data Lifeguard Diagnostic for Windows app provided by Western Digital but it stated everything was fine, however I'm not sure what to make of the results with smartctl, in particular '
190 Airflow_Temperature_Cel 0x0022 068 030 045 Old_age Always In_the_past 32'. I can't get Google to help me with this and am unsure how to proceed. Is it time to replace my hard drive? Are there other tests I can run? Is there anything else I can do to troubleshoot this problem(on Linux or Windows)?
