You don't need most of those items to test out the basics. You don't need the drives, the headset, the case, the mouse. What else can you do without to test for the basics?
Recently I put together a custom pc and when starting it up the lights and fans turned on. The tower would not recognize my motherboard, monitor, or mouse. The monitor just says no signal on every port. I have tried different cords and ports. These are the parts to my pc:
Intel - Core i7-7700K 4.2GHz Quad-Core Processor
Cooler Master - Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Asus - PRIME Z270-A ATX LGA1151 Motherboard
Corsair - ValueSelect 8GB (1 x 8GB) DDR4-2133 Memory
Samsung - 850 EVO-Series 1TB 2.5" Solid State Drive
Asus - Radeon RX 550 - 512 4GB Video Card
Corsair - VS 600W 80+ Certified ATX Power Supply
Microsoft - Windows 10 Home OEM 64-bit
Asus - VG245H 24.0" 1920x1080 75Hz Monitor
Redragon - S101 Wired Gaming Keyboard w/Optical Mouse
Corsair Carbide Series SPEC-ALPHA Mid-Tower Gaming Case, White/Red
Turtle Beach Recon Chat White Gaming Headset
I have looked through the instruction manual and can not find anything. It would be great to finally get my pc running and play some games. Any responses and help is thanked. Thank you!
