PC shuts down unexpectedly, flashing LEDs on the monitor, but the cause remains unclear.
Hey everyone, I hope someone can assist me. I just installed a new PC last week and now occasionally when it's running—sometimes at any time, not just at set intervals—the screen becomes extremely dark (not just losing color but fading a lot). After that, it restarts and my motherboard's red and orange LEDs start flashing. I've searched online but can't find a clear fix. Here are the specs: CPU i7-12700k, DDR5 RAM, MSI MPG Z690, GeForce RTX 4070 Ti, and a 12GB Corsair Vengeance.
BIOS might not support the 4070ti, so consider an update. Also, does your PSU meet the requirements for this processor?
Hello! I see you're asking about the Debug LED lights on your motherboard. They usually mean the status lights. Orange typically signals a RAM problem, while red indicates a VGA error. Have you tried re-seating the RAM and reinstalling your graphics card?
I haven't attempted to reinsert the RAM yet, I'll try it and check the outcome.
Recommendation suggests 700W is unlikely unless you're dealing with brief surges that trigger overcurrent protection. RAM could be a factor. My 5900X had trouble with the RAM I first installed, causing months of frustration before @BiotechBen introduced memory training. This issue seems more common with AMD boards than Intel, but it's worth verifying the board/processor compatibility on the manufacturer's list. If your RAM SKU isn't listed, it might be a contributing issue.
