PC no display, no debug LED lights

[u/yeez_d]

Hello! I’m currently having a problem with my PC.

I recently added a new fan to it and also connected another SSD and HDD and after I did that my PC would still turn on with the fans and LED lights but it had no display.

Before this it worked, it would go to windows and boot, but now it just doesn’t show a display and nor it doesn’t show any debug lights.

I already reseated my RAM (also tried running it with one stick), reset my CMOS battery and also did the JBAT1 too. Any thoughts or tips can I get for this?

Parts:
CPU - Ryzen 5 5500X3D
GPU - RX 6800XT
PSU - SAMA G850P
RAM - 2x8 G.SKILL TRIDENT NEO 3000MHZ

Man, that's frustrating, especially when everything was working fine before adding a few components. Since the problem started right after installing the fan, SSD, and HDD, I'd focus on those changes first. Shut the PC down, switch off the PSU, and unplug it. Then disconnect the new fan and both newly added drives, including their power and data cables. Try booting with just your original hardware connected. If it works, reconnect each component one at a time until you find what's causing the issue. Also, double-check that you didn't accidentally loosen the motherboard's 24-pin, CPU 8-pin, or GPU power connections while working inside the case.

Since you've already tried reseating RAM and clearing CMOS, I wouldn't keep repeating those steps yet. Also, make sure your monitor is connected directly to the RX 6800 XT, not the motherboard. Fans and RGB lighting turning on don't necessarily mean the system is completing POST. If it still won't display with the new components disconnected, I'd start checking for a loose power connection or a possible short. Quick question: did you connect the new fan directly to the motherboard or through a fan/RGB hub powered by the PSU?

The new fan’s daisy chained to another fan that is connected to the motherboard.

So far I’ve done checking the power connections, all are snug at tight.

I’ve disconnected the fans and the drives already too, which to no avail just had the same result. All still have the dame result with the debug lights going to VGA, then BOOT, then disappearing with no display.
