AMD 2600XP
GA-7VAXP-ULTRA
5900XT
MAXTOR 120GB SATA HDD
768 MB CRUCIAL RAM

recently i just had a maxtor 120gb SATA hdd replaced because it comletely crashed. However i've only had the new one installed a week and it has just shown the first sign of failure as the first one. I'll give you a run down of what happened to the first drive maybe one of you will know whats happening..

first pc failed to shut down, windows would shut down but would not powerdown unless mouse button was clicked.

second would not powerdown from windows, had to use power button

third pc refused to boot and data on hdd was unretrievable

got an error code from powermax and they replaced the drive but after only having the new drive a week and its doing the same it must be something in my system thats causing this.

Anybody got any ideas..
