Hardware problem.. can't point which component


I have some problems with my PC:

1) High ping (500+ ms) on speedtest.net, while my laptop is going 10-20ms surfing the same router.
2) HD disappearing, after a while when system is up (can be hours or minutes), 1 or 2 HD out of 4 is like shouting done, with a failure-like mechanic noise.
3) Video hiccups (freezes), the sound is going fine, all of the codecs. happens on all of the HD i have - not only on those that shutting done.

I formatted and reinstalled WIN 7 PRO 64 bit, only the ping problem is gone (3) the other two is still there.

the rack:

Intel Core i7-920
CORSAIR XMS3 6GB (3 x 2GB) DDR3 1600
EVGA GeForce 9800 GTX+ 512MB

I know its have to be Hardware :cry: but how can i tell which component is it ? maybe the PSU/MB have power failures ? maybe the HD is whats wrong and the rest is okay ? I feel like on HOUSE MD - too many symptoms :heink:

Someone can please guide me what to do ?

  1. Is it a ticking sound coming from the hard drives?

    Run a chkdsk /r on each hard drive.
  2. its not a repeating ticking sound its more like the hard drive is shutting down-going to sleep sound..

    I did the "chkdsk /r" on all the drives - all good.

    I did a another test, I wifi shared my laptop (which is fine) with the PC, i played couple videos that on the laptop in the PC and there were hiccups, and i played a video from the PC on the laptop and there where no hiccups, so what i conclude from that is the HD is not what making the hiccups problem, its either the graphic card, RAM or CPU.

    how can i find the problem ? :(
  3. Does the same thing happen in safe mode?
  4. I'm right now in safe mode, the video is like with a LAG, like 10 fps instead normal, still freezes but different kind..
    What its more likely to be ? the graphics card ? and the hard drive is shutting down without a connection to the video freezes ? RAM ? motherboard ?
    Please help me.. its a new and very expensive computer for me.
  5. Download speedfan, and check your temps.

    What kind of case do you have? To help rule out a heat issue, remove the side of the case, and blow a box fan towards it. If the freezing stops, it's a heat issue.

    What BIOS version are you on? The newest, is 0808.
  6. I have a Gigabyte Triton Case... I dont think think its heat issue but ill clean it out of dust tomorrow anyhow..
    the GPU temp is 54-55 and with video running it rises to 66 (celsius), system 50, CPU 42, core 0- 49, core 1- 49, HDs - 40, 44,49.
    and the bios ill upgrade but i haven't installed new hardware recently do its unlikely to help.

    thanks for being helpful aford10 !
  7. If it doesn't solve the issue, I think the next step would be to try and get your hands on another video card to test with.

    If you can, a beefier PSU to test with would be helpful too.
