Hi everyone,
First of all sorry for my English. It is not my first language.
I built a game pc early this month, every works fine until yesterday. I mostly used it to play bf2042 and use lightroom classic.
I was too dumb that to the AI Suit 3 Ai overclock feature. It restarted my pc and it went in to bluescreen and restarted itself. After that i went into bios and loaded default settings hoped to reset bios would help.
I started my pc again it works untill i Login to windows and the pc freeze and crashed. I tried restart it and restore to a previous point, it worked for a while and freeze again.
I tried to reinstall windows, and it works untill i update everything such at drivers and it freeze and crashed.
I tried to reinstall windows again and it crashed during installation.
Now it can't boot into bios and no signal to my monitor.
I checked the code on my mb as listed below: some code is not in the manual so i looked it up online

Here is my spec:
Cpu: Intel Core i9-12900K 3.2 GHz 16-Core Processor
MB: Asus ROG MAXIMUS Z690 HERO ATX LGA1700 Motherboard
GPU: MSI GeForce RTX 3070 Ti 8 GB SUPRIM X Video Card

Ssd: Samsung 970 Evo Plus 1 TB M.2-2280 NVME Solid State Drive
Cooler: Corsair iCUE H150i RGB PRO XT 75 CFM Liquid CPU Cooler
Power: MSI MPG A-GF 850 W 80+ Gold Certified Fully Modular ATX Power Supply
I just made a new build with an Asus X99-A II mobo, Intel Xeon E5-2690 v4 ES CPU, GTX 970 and 2x16 GSKILL DDR4-2400 RAM. After putting together my build, I can get into the BIOS, but after I reboot, my PC won't POST and the Asus motherboard LED reports code 19 "Pre-memory PCH initialization started". The CPU_LED is also on. It stays that way on subsequent reboots until I reset the CMOS. Then it boots into BIOS again but on the next reboots it gets stuck at code 19 again.
Anyone had suggestions?
I finally decided to bite the bullet and upgrade my tried and true i7-6700k in an old Antec P-180. I ordered these parts: https://pcpartpicker.com/list/zWwG6Q# and intended to move a RTX2080 and 2TB NVME from my current PC.
I assembled all the parts and hit the power switch fully expecting to deal with some Windows issues but instead I never made it out of POST and the display never activated. I tried all the DP and HDMI ports on the 2080 and the DP/HDMI on the MB but never got any output. Sadly the MB doesn't have a post code 7-segment anymore and the dumb case I ordered doesn't have a power LED for the Q-LED core functionality. I added an LED from an arduino kit and I was getting fast blinking (DRAM not detected) followed by slow blinking (no VGA). Everything attached to the MB powered up and the DRGB LEDs started cycling colors so at some level the MB seemed to be working.
Troubleshooting steps:
-
Removed and reseated both sticks of ram, swapped them, tried each one individually, and finally tried them in the "wrong" slots. Same result every time.
-
Removed checked CPU, everything looked pristine as expected.
-
Removed GPU
-
Removed all attached USB devices
-
Hooked up a TTL->USB converter to get the POST codes from DEBUG-COM port and got this stream of codes which I ran a VLOOKUP in Excel to get this human readable list (Thanks EVGA for publishing a list of what each code means):

Clearly some memory related error codes in there.
The RAM wasn't on the compatibility list but I've never had an issue with other builds in the past as long as the speed/type matched up. I ordered RAM from the list and it is due in tomorrow.
Is there anything else I should look at or what is the next most likely culprit? Seems odd that both modules would be defective.
Hi guys. I need help and I have no idea what to do. I have built a new PC with a Ryzen 3900X a Asus X570-E motherboard Corsair Vengeance RGB Pro 32GB (4x8GB) DDR4 3200MHz RAM an MSI RTX 2060 GPU and a Corsair RM550 PSU. For the first week everything worked perfect. Now when I try to boot into windows I get a black screen with the orange DRAM light flashing on the mobo as well as the error code 3E and a black screen. When I take out all sticks of RAM and place one back I can boot into windows. I’ve tried to reseat the CPU as well as change the RAM settings in the BIOS and BIOS updates. Nothing is working and I have no idea what to do
Hello, I'm not a complete tech noob, but I thought before I go out and buy replacement parts, I should post here and see if anyone has some ideas.
Edit: Sorry, msi gd65 z77 is the motherboard. Error Codes I believe are:
4F, DXE IPL is started
03, System Agent initialization before microcode loading
19, Pre-memory PCH initialization is started
56, Invalid CPU type or Speed
46, OEM post memory initialization codes
49, OEM post memory initialization codes
55, Memory not installed
36 CPU post-memory initialization. System Management Mode (SMM) initialization
Short Version:
Won't post. Motherboard does this: https://www.youtube.com/watch?v=a4-_DT4Z9OY
Long Version:
For about a week, the computer wouldn't boot unless I restarted it ~10 times. Sometimes I would switch off the power supply, sometimes that seemed like it helped other times it didn't. Eventually one day it won't boot at all no matter what it did. But, the strange thing was, when it was booting before (after many attempts) it would be fine all day ~12 hours with all sorts of load on video, cpu, ram, power etc. Also, when I looked at the debug codes displayed on the motherboard LEDs, it rotates between about 6 of them. https://www.youtube.com/watch?v=a4-_DT4Z9OY
I've unplugged everything but ram, cpu and power supply and it still goes crazy like this: https://www.youtube.com/watch?v=a4-_DT4Z9OY.
I don't think it's the power supply. I've had power supplies fail, and the symptoms of that are usually intermittent restarts, but like I said when it did boot all the fans, video, harddrives, etc worked perfectly. All things get power even without post, and power supply fan is working.
I don't think it's the ram. Ram tends to cause intermittent crashes. I've tried the ram I have in different slots and only 1 instead 2. Didn't work. And like I said when it did boot I had the ram filled 3gigs+ working 12+ hours. I feel like it should have shown symptoms then if it was ram.
On the motherboard side I've tried, different bioses, reseting the bios, pulling the battery and reseating the ram and power cables. Nothing worked.
My gut tells me it's the motherboard or the CPU. When I first got the CPU it had a bent pin, which I fixed. Since I've owned this computer 2+ years I've overclocked it (midly). No overheating problems though. I suppose it's possible that the overclocking a stressed pin could cause this problem. It's my only guess other then some freak quality problem in the motherboard.
Thanks for any help you can provide me.
I got my parts yesterday and began to put the things together. As i first time builder i encountered some problems, but all in all it went quite well :)
Now that i try to boot my rig i keep getting the following error code on my asus z170 deluxe:
-
-
Error Code 14; Pre-memory CPU initialization is started --> This is only like 1 second and disappears
-
-
2) Error Code 19; Pre-memory PCH initialization is started --> only just one second
THEN it get's stuck on the error code 53, which stands for memory initialization error. invalid memory type or incompatible memory speed. the memOK LED is on (after flashing several times) and some rebooting circles.
My RAM sticks are g.skills ripjaws V 32GB (4x8) 3200 Mhz. According to G.skill, these sticks are compatible http://www.gskill.com/en/product/f4-3200c16d-16gvk
I also tried to boot with different amount of sticks in different slots but got always stuck on the error code 53...
Can you guys pleas help me with any advise?
Is it a problem, that the speed of my RAM is to high for a first boot? but how can i adjust the speed in BIOS when i can't reach it?
So yesterday I built my new PC with an i9-12900kf, ASUS Z690 gaming e, and 64Gb of Kingston fury ddr5 5200. The problem is I can't get the PC to boot consistently with either XMP I or XMP II on 4800 or 5200. So far I tried to update the Bios on the latest version, bump the VDD and QVDD Voltage stepwise up to 1.3V and lower the frequency to 5000. In 90% of the time when restarting, it won't boot and freezes at code 20 (Pre-memory PCH initialization is started) or 33 (CPU post-memory initialization). The only way I can run my RAM consistently is in auto mode at 4000MHz.
Does anyone have the same hardware and encountered a similar problem? Or does anyone have some ideas about what I could try? I'm new to RAM overclocking so please bear with me if I overlooked an obvious thing. Many thanks in advance.
it is expected for 4 sticks of ddr5 to max out at 4800 or lower. looking at ASUS qvl for your board, there is only one entry for 4x16 ddr5, and it is running at 4400. a similar trend exists for all boards so it is not just this model. this problem is a mix of ddr5 being new and bioses/boards not having had much time to figure out support, and also simply the memory speed and complexity is getting so high that the signal integrity is compromised. if you need 64gb of ddr5, it is strongly recommended to get 2x32gb which is much easier to stabilize - the qvl for your board lists results as high as 6400.
I can't say it any other way - it's a shitshow.
I've been struggling with a 12700k, a Gigabyte Z690 Aero D, and I've already tossed an Adata kit for a G.Skill kit - and that's with 2 x 16GB.
Now, I'd thought it was more or less stable at XMP and with an updated BIOS, but from what I can tell there's still something goofy going on. Specifically games just straight up crashing to desktop, no error given, or if there is, it's a DX12 error. Other stuff like individual Chrome tabs crashing.
Now, my Gigabyte board is definitely on the cheaper side - it's a 'Creator' board like ASUS' ProArt series - but it's also packed with the features that I actually want and use.
And I thought I might like working with a Gigabyte board. Turns out, not so much.
