RAM: G. So, I have a Z390 FTW motherboard with a. Where would you start troubleshooting and in what order? CPU Fan runs, chassis fan runs, onboard yellow LED lights up when powered on but wont boot/no display/no beeps. I flashed with the latest BIOS version 7C84v15, released as my Motherboard was not compatible "out of the box" So what can the CPU debug light mean/indicate is wrong? ![]() My main question is if i could narrow down the potential problems to help with the troubleshooting: However whats also lighting up is the CPU debug Light on my Motherboard and i get no display.Īfter reading on the internet it seems like a lot of users encounter this problem. The RAM light was lit on the motherboard but the CPU light flicked on for a. So i turn my newly "made" computer on for the first time and everything looks good: all components seem connected properly, fans working, gpu lighting up and motherboard all active. Wait for 3-5 mins until the green led is off, which means BIOS is updated. Hoping anyone could help me out or give me some directions. Just disconnect all hardware to the motherboard.New member here. This is to try and see which hardware doesn't pass the BIOS test. If it does then install the GPU and monitor and keyboard and mouse and see if you get Video Output. Now install one RAM Stick and see if the DRAM Trouble LED light goes off and the GPU light goes on. If it still stops on the CPU Trouble LED Light with just the CPU installed then you either have a defective CPU or Motherboard. If it does, at least that indicates your CPU is good and passed the BIOS test and found no RAM installed so it lit up the DRAM Trouble LED light. Power up and see if the CPU Trouble LED light goes off and the DRAM Trouble LED light goes on. Just leave the CPU installed and no other hardware. ![]() If doesn't and you still get the CPU Trouble LED light on your motherboard, remove all the connected hardware to the motherboard including GPU and Keyboard and mice. Remove all the RAM sticks except one and see if you get Video output when you power up. ![]() Is there anything that I can try to fix this ? Sadly I don’t have any spare atm and I cant go to a shop So I think what is left is only trying another motherboard or CPU removed everything on the motherboard except CPU ![]() Reseat CPU and reapply the cooler and paste reset cmos (by removing the battery and waiting few hours, ) try different bios update by flashing my motherboard use different rams ( my old ones HyperX Kingston Fury 2666MHz DDR4) put rams in different slots, use single or double rams Rams CORSAIR Vengeance RGB Pro 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 3200 My motherboard has in Ez debug LED it was shining on Dram then after updating my bios to latest version only CPU LED was on I updated my old pc all component except GPU -thanks market – and hdd and ssdĪt first it worked fine, I then increased the rams speed to its advertised speed (3200), it worked fine after a while my pc was restarting randomly, I decreased the ram speed to 3032, it restarted and worked fine after a while it shut down and now when I turn on the pc it powers up (fan spinning, rams shinning) but there is no display or my mouse doesn’t work, however, my keyboards keys light is on. I have an issue, when I turn on the pc it powers up (fan spinning, rams shinning) but there is no display or my mouse doesn’t work, however, my keyboards keys light is on
