Upgraded computer won't Boot. Any ideas?

[jmig 100]

After reading over and over the virtues of AMD’s 7800X3D CPU, I decided to upgrade my flight sim computer. Besides the 7800X3D I purchased Asus’s ROG Strix B650E-F mother board and 32 GB of Corsair Vengeance DDR5 Ram. I also added a Cooler Master 360 water cooler and another 2TB M202280 drive to round out the upgrade. I reused the case, 1000 watt PSU and RTX 3080 GPU.

The system went together without any issues until I attempted to boot the computer. All I got was a yellow LED that Asus says means a DRAM issue. I swapped the modules to different slots, tried one then the other module alone. I attempted to run Memtest86 using a flash drive, but since the system is not even going to POST, I can’t see what the test results may be. Since the USB drive should be self-booting and doesn’t seem to be doing so, I suspect the system is trying to boot from the original C drive that contains Win 11 but doesn’t get through POST.

Searching the web for ideas I downloaded a BIOS flash to another USB drive and tried that. Again, I don’t think the system recognized the USB drive. I didn’t see any flashing that I associate with a USB drive reading and writing.

Again, from web advise, I pulled the CPU, looked it over, and reinstalled it. That didn’t help.

So, I am left with a dead computer and scratching my head. I have over the last 30 plus years build over a dozen computers. I have had my share of startup issues (usually with trying to get Windows to load), but never have I had a dead system. I am relucent to send everything back to Newegg. I don’t know if the problem is with the CPU, MOB, or RAM.

 

Any advise from the community?

Either the RAM is bad or you have a bad motherboard. Even if your Win11 drive was completely failed, you should at least be able to get to the BIOS setup screen. If you have a light showing a DRAM problem, that is probably exactly what it is  - although a MOBO memory controller problem could masquerade as a DRAM fault.

Check and make sure that your RAM is properly seated in the slots.

Is the MOBO having the most up to date BIOS to support the CPU?  When I brought my i5 13600K a year ago, the shop offers me they would update the BIOS to make sure it would boot.

If you replace your motherboard and CPU, it is possible that the computer might boot again, but only if your new CPU is from the same manufacturer. But in any case you are advised to create a boot drive to recover the OS, in your case Windows 11, from your old HW and SW. I guess in your case you will have to install everything from the scratch.

And yes, if you can‘t even enter the Bios, you might have to check the correct assembly again.

I recommend you do a hard reset of the CMOS memory BIOS settings using the button or jumper on the mobo, just to make sure that everything, especially the memory settings, is set to the mobo's defaults.

Corsair and AMD are in general not good friends. G Skill and Kingston on the other hand are.

Is the Corsair memory model on the QVL listing of your particular motherboard?

Which version of the Corsair ram are you using? They sell an AMD EXPO version for AMD boards and an XMP version for intel setups. They look the same, but whilst each type will usually work in either situation at base memory frequencies, in some cases they do not.

Thank you everyone for your suggesting's and advise. I got it working. I contacted Asus chat support and the agent walked me thorough reflashing the BIOS. That solved the problem. Now, I am dealing with trying to load Windows when it wants an internet connection and I haven't installed the drivers yet, so no internet. Oh well, as the Navy SEALS say, "The only easy day was yesterday." I will get it working.

I had a similar issue when I upgraded my whole system, I found that the new SSD windows boot sector had formatted to MBR and not GPT (or vice versa, can't remember which), converted it by enclosing the new SSD in an external drive, changed the boot on my laptop using a partition manager, put the new SSD into the new build and it booted up.

Worth a look.

Yes, so I just found out. It seems the RAM I purchased was incompatible with the ROG motherboard. Newegg refunded me the memory and I will reorder one from the "approved" list.

You should install a new fresh Windows after you have swapped motherboard.

Yes, I will.
