I have 3 HDD's in this computer, I installed  a server I was testing on this Maxtor  Sata II is showing up in the bios , and in the computer - in the boot menu , the partitions are good. When rebooting and this only sometimes  there is no HDD showing in the boot menu - or anywhere. Sometimes its on and off the HDD is only a year old and half  I rechecked the connections I am thinking it might be the power connection on the HDD. I installed a new  OCZ power supply 700 watts because of the graphics card  ATI Radeon X1800 CrossFire Edition 512 MB requirements.  I am baffled do you have any suggestions or advice - it does have a 3 yr warranty  Thank you in advance ---Jackie
