All right, so, I've already bought a new hard drive to install, and I have my copy of Windows ready to install. Unfortunately, with no hard drive plugged in, the case power switch is NOT able to power off the system. Furthermore, I tried powering on the system with the new hard drive plugged in, and I am unable to boot the BIOS or any other boot menu. Is my motherboard dead?
I don't know how soon any of you will reply, so I have to go to Micro Center and buy a motherboard before they close. But, I'll go ahead and list my specs.
PSU: Antec 620W
RAM: 16 GB
GPU: Nvidia Geforce GTX 970
CPU: AMD FX 8350
New HDD: Toshiba X300 8 TB
MOBO: Gigabyte 970A (or something)
Optical Drives: DVD-RW and BD-RW
CPU Fan: Cooler Master Hyper 212 EVO
Case: Cooler Master Storm Enforcer (Discontinued)
Audio Card: Asus Xonar DSX
I think that is enough info for now.
Update: My motherboard came back to life! My Windows install is finishing up as we speak. Thank the spirits beyond that I do not have to buy a new motherboard (hopefully). What could have caused the motherboard to take so long to finally work?
