Installed a 1 TB hard drive and started the computer.
Computer would not post and noticed a puff of smoke from the rear of the machine.
Quickly unplugged the machine and notice the new SSD was very hot.
I took out the SSD and left in the original SSD, but the computer would not beep: just four beeps with a red light, then a two second rest and then 4 red beeps again.
I disconnected all components, except the power supply and the graphics card and plugged in the unit. I notice the green light on the power supply was on, but turned off when I pushed the power button. The computer would not boot and repeated the 4 beeps.
Question: do you think I fried my mother board or the power supply.
Any help would be appreciated.
If this has happened to me, then this has probably happened to someone else.
Thanks
