Vanishing harddrive

Hi folks prob wrong place so sorry in advance

ok my problem - My hard drive disappears it is a western digital 500gb sata

1: doesnt matter which port it is plugged into eventually happens
2: replaced hard drive still happens
3: replaced sata cable still happens
4: replaced motherboard still happens
5: happens when computer is running games, programs etc doesnt seem to discriminate
6: happens if it is main drive or if it is just as a backup one of them or both will go
7: if it is main drive computer wil freeze have to hold button down to turn off when it restarts bios sees the hard drive but windows wont load says disk read error alt, ctrl, del to restart does not work
8: only way i have ever got it to restart after this crash is to pull out sata cable and put it back in, different slot/same slot makes no difference out and in and it works again

anything i missed feel free to ask please help me!!

Have you tried running WD's diagnostic utilities?:

Edit: Reading your list a bit more carefully, I still say run WDs utilities, but other ideas that occur:

Given that you've replaced the drive, mainboard, cables, etc and it still happens, and that removing and plugging the sata cable back in allows it to start, have you checked your PSU? If you have an extra, might not be too much trouble to swap it out. Also, although your system specs don't mention an optical drive, if you do have one installed, try unplugging it and any other HDs (that aren't running windows).

Thanks for replying

Yes i did it didnt have any problems i replaced it with a brand new one eventually did same thing if i reinstall windows it will take a couple weeks before it does it

Got a new one coming in a few days just got a gtx460 so upgrading but that doesnt explain why it starts after a few weeks or why taking cable out and putting it back in fixes it or why it does not affect bios only windows as it loads

Yes i got a ide optical only one hard drive had iot unplugged before and it still did it so nothing to do with drive (took cable out of motherboard)

What HD controller mode are you using (AHCI, RAID x)?

Another simple attempt, assuming your RAM is in 4 sticks, would be to remove 2 of them (taking note of the mainboards RAM placement config).

Forgot to mention also replaced ram completely, placement not sure what hard drive controller is but bios says sata ide with choices for raid or ahci

The replacement HD...did you do a new install or restore an image or clone of the original problem drive?

brand new install

Did you let windows install the chipset drivers for the mainbord or did you install the 64 bit chipset drivers from the CD or here?:
