Please help me on this one, I have two separate PCs
First build:
• Ryzen 5 7600
• MSI B650i Edge Wifi
• Corsair 6000mhz 32gb
• GTX 1660TI
• SF750 Platinum PSU
Second Build:
• Ryzen 5 5600x
• Gigabyte B450m Ds3
• Corsair 3200mhz 8x2gb
• RTX 3070 Gigabyte
• Segotep 750w Gold PSU
Both GPUs are connected directly to the PCIE slot, no riser cables. CSM mode is disabled for both build. Updated bios for both builds. Both power supply are working well. Separate 6+2 cables are used for the RTX 3070 (not daisy chained)
Scenario:
✓ 1st test:
Plugging my RTX 3070 on my "first build" won't boot, but testing it out with the 1660ti works well and boots into windows.
✓ 2nd test:
Plugging my RTX 3070 on my "second build" boots to windows with no problem.
✓ 3rd test:
Ruled out the PSU for the "first build", I got my SEGOTEP PSU and tested it out on the first build and no boot with the RTX 3070
• It booted with the 1660ti
✓ 4th test:
Got my SF 750 Platinum PSU and tested it on the second build with the RTX 3070 and it boots with no problem
✓ My main problem now is the Black Screen / No Post / No Signal / Cant Boot into BIOS & Windows when using the RTX 3070 on the "first build" but using other GPU works
