I come back from vacation, and the hard drive with my OS on it is dead. This is fine. I also have a 500GB drive with music and such on it. They're all Seagate. I buy a refurbished hard drive off of newegg, and am able to install Vista 64 bit on it. Great! I remove all the jumpers which apparently had been limiting me to SATA I. So they're both SATAII.
Later on (maybe an hour later) after everything is back in the unit, I press the power button. The fans start up for a second, then nothing. The only light on is the one saying "MEM PWR" and the one that indicates power going to the motherboard. I try putting the jumper back on. That doesn't work. I try replacing the power chords and SATA chords going to the motherboard. Nope. I try removing the new 750 GB hard drive. It works! It works with the 500 GB drive plugged in.
So, I think its the new hard drive. I print out the warantee stuff and head off to my local electronics store to pick up another hard drive while I wait.
I plug in my new 1TB Seagate 7200 rpm, and same thing!! It 'feels' like some sort of electrical short. I can hear a tiny click, but that could just be everything powering down.
Please help. I'm having trouble finding anything about this online. I've checked my wiring and such. Everything seems okay.
I have 8GB of RAM (G-Skill).
1000 Watt Power Supply.
Two Geforce 9800 GX2 graphics cards.
Nvidia 780iSLI board.
