At first, my hardware:
Motherboard: MSI B550M PRO-VDH WIFI
CPU: AMD Ryzen 3 3100
GPU: MSI GeForce GTX 1050Ti Low Profile
RAM: 2 x 8 GB HYPERX HX432C16PB3A/8
PSU: Chieftec CSN-650C 650W
SSD: ADATA SWORDFISH m.2 2280PCIe Gen3x4
Body: Aerocool Playa Slim
So, the problem is no video signal after launch (tried 3 displays and 3 cables), only 1 long beep and 2 short beeps and thats all. Removing GPU don't fixing the problem, try reassemble it many times with ram too, trying various ram combinations, nothing happens. PC have around 1 month, yesterday everything works fine. Somebody can help me fix that?
