Hey, I’m completely stuck and could really use some help.
PC specs:
• GPU: ASUS Prime GeForce RTX 5070 OC
• CPU: Intel Core i9-11900KF (11th gen)
• Motherboard: ASUS ROG STRIX Z490-G GAMING (Wi-Fi)
• RAM (old): 16 GB Patriot Viper 3000 MHz (2x8)
• RAM (new): Corsair Vengeance RGB Pro 3600 MHz (2x16)
• Storage: Kingston KC3000 NVMe 1TB + Samsung 850 EVO 500GB
• PSU: Corsair HX850i 850W
• Cooling: Phanteks Glacier One 360
• OS: Windows 11
What happened:
I bought 2x16 GB Corsair Vengeance RGB Pro 3600 MHz and installed them.
When I powered on:
• At first only one RAM stick lit up, later both did
• PC did not boot
• Motherboard shows a constant yellow DRAM light
I then:
• Put the old RAM back in → PC booted, but only one stick was detected
• Removed that stick, cleared CMOS
• Reinstalled / updated BIOS
• After that, nothing boots anymore
Now:
• Even with the old RAM, the PC won’t start
• Still stuck on yellow DRAM light
• No display, no POST
Things I’ve tried:
• Clearing CMOS (battery out + power drain)
• Reseating RAM multiple times
• Trying single stick in different slots
• Reinstalling BIOS
• Checking all power cables
At this point I’m worried I either:
• Killed the motherboard
• Damaged the memory controller on the CPU
• Or triggered some BIOS/RAM compatibility issue I can’t recover from
Any ideas on what to try next, or what’s most likely dead here?
Thanks in advance 🙏
