Burnt out

[BlueMage]

Hello all,

First time posting here but if anyone can help me, I will gladly name my first borne after you! So about four days ago 10.9.22 my pc took a power surge. After the surge it would only crash then restart in an infinite loop.. I quickly removed it from the power and spent the rest of the evening looking at every piece connected to the motherboard. After inspecting everything and plugging it all back in. It would not get past the windows logo before crashing. I replaced the ram, both SSDs, and all of the cables. Crashes. I replaced the motherboard with the new ram and drives keeping the gpu and cpu the same. Crashes. I took my gpu out of my machine and placed it into another machine. It works just fine. I was unable to try the cpu in another machine as I do not have another LGA 1151 on hand. After speaking with some friends and a few tech support, each having the machine for hours and not coming up with anything, they offered for me to flash the bios. That did not work either. If I am understanding correctly, a cpu won’t even boot if the cpu is faulty. If this is incorrect please feel free to correct me. If anyone knows or has ever ran into this problem please tell me what you did to fix it. I am at the end of my rope. My next step is to buy a new cpu. If it helps, when the machine crashes it goes to a BSOD but it is never complete. I get the “” face but the error message never fully posts.

g’day and welcome to the Forum.

you don’t mention the power supply.
after a power surge, the first thing I’d replace is the PSU.

you also don’t mention if you have tried reinstalling Windows.

next I would dismantle everything and reassemble on a piece of carboard.
only reconnect the essentials to get into BIOS at this stage - no no DVD unit, only one RAM stick, no GPU if the CPU and mobo support that, no mouse, even leave out all the drives.

we just want to press Del, or Esc, or F1 or whatever key is needed to get into BIOS.
once in, look around and see if it thinks everything is OK - BIOS version, date/time, memory etc.
then shutdown and connect the drives, get back into BIOS and see if it can detect them.
also stay in BIOS for a while to check the machine isn’t shutting down for some reason.

then reconnect everything, still outside the case.
this is when I’d be reinstalling Windows.
get the latest build via the Windows Media Creation Tool and create a bootable USB stick.
try to reinstall Windows, this process will highlight any issues as it reloads everything.

Hey so I guess my implication was clear, I did all of that. When I replaced the motherboard I replace EVERYTHING. I replaced the PSU, the case, all ram, all hard drives, all cables and ports (usb and usb-c), the heatsink, the paste, the fans. Literally the only thing that is not new is the GPU and CPU. When I tried to install the os it would freeze or crash. Please forgive me I am not joking when I said I replaced it ALL and that I’m burnt out. I’m glad to see the quick response here though, it gives me hope. If it’s down to me replacing the CPU then that may be it.

sadly, if everything has been replaced except the CPU that sort of dictates the next thing to try!
and the GPU works in another PC so that can be ruled out.

I’ve only ever seen two CPU’s die in my time from surges, so you’re in an elite club! (y)

I was afraid of that. So I guess I’m replacing it. In Future should I no longer assume be able to boot to bios a quick indicator of operating CPU? I mean the thing shows up and clears POST. I’m able to mess with the clocking and the usage meter.

[Bruce]

can’t say I have ever tried, but I see no reason why you shouldn’t be able to boot straight to BIOS even with no CPU installed.
so probably not much of a test really in determining the validity of the processor.

@BlueMage - any news?
