Updating and fixing my computer.
Updating and fixing my computer.
Hi everyone, I'm writing here mostly to become more confident I did everything right. My story is as follows: I've installed new Motherboard (MSI Z 370 A Pro) for my 8700K CPU since my previous MB died on me. Being a happy owner, I was excited to boot up my system. However, the only thing I saw/heard was my GPU fans spin 100% and No-Display signal on my monitor. I started digging up some info, tried to reseat the cables (both 8pin and 24pin) - nothing helped. Then, seemingly randomly, PC booted up and went to the Windows just fine. I thought that was strange since I didn't do anything deliberate to "fix" it so I was mentally prepared it might die on me again. Couple of hours later (I stress tested CPU/GPU with Aida64 and some graphic benchmarks - all was fine) - PC shuts down on me when I'm on Discord with my friends. I suspect this wasn't due to high loads or anything, since it passed stress tests before. After trying to turn it on again - same thing, fans on GPU spin really loudly and nothing shows on screen. Figured, this can't be GPU since if I remove it and use processor as iGPU - same thing. Started digging some info online and noticed that MSI boards have EZ Debug LED thingie on the right and I noticed it was lit with a white color on CPU fail/not detected. So that narrowed down my suspicions. Read up online that this could be due to BIOS version, incompatible ram sticks etc. Tried each RAM stick solo in every slot - didn't help. Removed GPU (which is RTX 2080) since it's most likely not connected to the failure. Tried to reseat each cable in the PC case. Didn't help at all. Being very angry and frustrated - I went to sleep, but couldn't get any of it. Woke up couple of hours later to give it one more try and it randomly turned on (no EZ Debug LED was visible), but obviously no display since I disconnected GPU. Reconnected GPU. Turned it on - booted up to Windows just fine. Figured I might as well update BIOS. Prepared Flash Drive. Restarted PC to get into BIOS and it doesn't boot - same EZ Debug LED on CPU error. It all seemed very random with no logic behind it. Went to sleep and in the morning I decided to reseat my CPU heatsink+fan. For the good measure, also checked CPU and the socket - socket was just fine, no bent pins - CPU was also seemingly fine. Put it back in the socket - make sure it stays there firmly. Installed heatsink, connected every fan and tried to boot up without GPU. CPU Led wasn't visible. CPU passed the test (or at least motherboard said so) and now showed that there's no video output (duh, no GPU haha). So I installed my RTX 2080 back in the case and prayed it boots up. It booted up to Windows, I can see the image on my monitor. Stress tested with FurMark + Aida + some Heaven benchmark. Totaling 2 hours of testing - nothing bad happened, everything seems fine. So my question to you. How probable is it that reseating CPU was the solution? What might have been the problem behind it? Because in my mind - if the CPU wasn't seated properly, it shouldn't have booted up, not even once. But it randomly did. Please let me know if I should feel safe from now on. Thanks for reading my story. Appreciate any input here. Cheers!
The chance of a faulty CPU being the issue is significant if that's the solution. However, it's impossible to guarantee 100%. Could you share the PSU details? Just for fun.
Consider purchasing a reliable power supply unit right now. This particular model falls into the budget range and is commonly found in the PC Killer category. It’s crucial to get a solid PSU immediately to avoid damaging any components or the entire system. You’re essentially relying on chance right now:p. Aim for a mid-range unit from the PSU tier list, and if you plan to upgrade later, target around 850W for the 3080 class card. The D.F. revolution is currently the top choice offering exceptional performance at a reasonable cost.
Review the list and share your findings here. There are numerous low-wattage PSUs in that range. Remember to tag and quote us so we can see your response.
