More organized info:
I added some more details and made some things clearer.
What is happening:
1. I plugged in my external hard drive for the first time and computer crashed. The plug is a USB 2.0, while the hole is USB 3.0. The external hard drive is a western digital caviar blue 500GB encased in a Rosewill external case, which I had sitting at a corner for several years. The Rosewill external case does not have a ground plug for its power cord. It just shut down automatically. I thought I saw a spark.
2. I plugged in my printer as well, and my computer crashed. I recently built a new computer with these specs:
I am wondering if anyone out there might know what is possibly happening so I can take the necessary precautions next time and hopefully solve the problem.
My components:
My motherboard: GIGABYTE G1.Sniper Z87
PSU: XFX 650W
1. 3 HDD
2. 1 SSD(OS)
3. 1 DVD writable drive.
4. 1 XFX Radeon HD 5870 GPU
5. Intel 3.40 GHz i7 cpu.
6. 16GB Ram by corsair(2 x 8).
My PSU specs:
ac input: 100-240VAC, 10A, 50/60Hz
dc output |+3.3v..|. +5v....|. +12v..|. -12v....|+5VSB..|
................|..24A...|.30A...|...52A..|...0.8A...|..3A.......|
................|....170W.........|..624W.|...9.6W..|...15W...|
................|.......................650W..............................|
I have no idea what those numbers mean. Hopefully someone knows what is going on with my computer.
Here are the possibilities according to what I have researched:
1. PSU wattage is not enough.
2. Faulty USB 3.0 ports.
3. The electrical outlet may be broken(the grounding plug may be broken), since the plate has broken loose after I banged my desk against it. But this may be unlikely since if this is true, than my last computer should be shutting down when I plug my USB in the back of the computer. Then again my last computer only had 2 HDDs plugged into the motherboard and no DVD drive.
Again, I am plugging USB 2.0, external HD case and my printer, into a USB 3.0 slot and my computer crashes.
I took the HDD out of the external case and plugged it directly into the computer with SATA cord and it works. The problem with plugging USB 2.0 into USB 3.0 port at the back of the computer is still there.
I have contacted Gigabyte, but they never responded.
As you can see from the reviews, I am probably the only one having this specific problems with this motherboard.
