New PC Constant Crashing

[zackk295]

I built my first computer in January, and have been having nonstop problems with it. I use it for mining (initially at 70% TDP 70% fanspeed, after learning of the VRAM temp problems, I bumped it down to 50% TDP 70% fanspeed) and 1080p gaming while I save for a 1440P monitor. The day after I first built it, a driver bug forced me to reinstall windows. A few weeks later (before I started mining), my PC stopped recognizing my peripherals and giving monitor output. I took it to a tech repair guy near me, who told me that it was probably my MOBO or CPU. I exchanged my MOBO with no luck, so I RMAd my CPU which seemed to fix it. A few months ago, my PC began hard-crashing when I would leave it mining for more than a few days at a time. It started crashing more and more often, eventually pretty much crashing whenever I wouldn't touch it for more than an hour. I also began seeing the occasional BSOD crash, always showing different codes. Also, after it crashes, and sometimes even when it hadn't recently, when I turn it on, it the error code display cycles through different error codes. Sometimes it will stop on A0 or A9 and boot properly, but most of the time it will get stuck on 55 (the code I saw when it stopped recognizing my peripherals), but without some of the lights that make up the second 5 on. When it does this, it turns off with an audible "click" and then after a few seconds tries to boot again. Someone on a Nicehash forum had a problem with hard-crashing during his mining and the forum said that it was because he had lowered his TDP without lowering his clockspeed. I tried that and my computer mined for a few days straight without crashing (I thought it fixed it) but yesterday, after a 4 hour DOOM eternal session on cranked graphics and a few hours of Hulu it crashed again, but this time when I tried to reboot it, it kept crashing constantly. I let it sit for the night and tried again this morning but now whenever I turn it on, it does the cycle thing, for like 5 minutes at a time (before it was like 30 seconds every time it did it), and then when it finally boots, It crashes almost instantly. Ive had a mix of numerous BSOD crashes, a few "windows ran into a problem and needs to restart" crashes and whenever it doesn't do one of those two, it hard freezes about 5 minutes after I get into windows. I've tried reseting the CMOS battery, resetting my BIOS to stock settings, reseating the RAM, doing the /scannow command in the cmd prompt, and downloading the intel processor verification software thingy (I cant check for the exact name because I cant boot into my computer but its the thing to check the health of your CPU). I try to keep the computer clean (hitting it with compressed air every week or two) and currently, I mine with the side panel off for more airflow. I monitor the temps while mining, and I try to occasionally ALT + TAB when I'm gaming to make sure it's okay, they've been pretty good so far (aside from 3090 Vram lol).

 

The guy I took it to said I did a great job building it and that everything was done correctly, so I don't think it was something I did

 

CPU:i7 10700kf

MOBO: Asus Z490 E-gaming

Ram: 16GB (2 8GB sticks) Corsair Vengeance Pro RGB 3600

SSD: Samsung 970 evo plus 2TB

GPU: 3090 FE

AIO: Coolermaster ML360R

PSU: Asus ROG THOR 850

Case: Lian li 011 Dynamic

Fans: 3x Noctua NF p12 redux on AIO, 3x Coolermaster ML360R fans, 3x Coolermaster Sickleflow RGB 120mm

 

I was never able to recreate the conditions it crashed under before, but now it crashes so often I pretty much don't have a chance to even get loaded up into windows

 

Can anyone help? I'm a college student on a very limited budget and I cant take the PC anywhere until I get back home.

 

 

Thank you so much for reading all that, I'm still pretty new to building computers so I tried to think of everything relevant that I could include

Have you tested the memory?  The peripherals thing sounded like software.

1. Never change something in your bios except the cpu and activating xmp on ram.. It doesn't even change that much and I just wouldn't really do something there 

 

2. Is your mining software in windows or is it a own OS it could mess with your OS because it is at kernel level so... Yeah yk

 

3. If you format all you drives and reinstall windows without the mining software it should work (and reset bios settings and update bios) 

 

4. If the upper stuff still doesn't work you have probably a wrong placed cable or a corrupted bios/ broken motherboard

I’ve reseated it in the same slots before. When I had the problem with my peripherals and output, the guy found that by running it in single channel mode It would function normally while I waited for my RMA. I will try and use one stick in the morning and see if it still crashes.

Running a single stick in single channel mode is the really old test for memory.  A bad memory stick is possible then.  There is also straight up memory testing programs that will do all the sticks at once.  While it still takes a while it’s a lot faster.   It doesn’t necessarily find all possible problems but it if does find one it’s an actual issue.

All I did in the BIOS was enable Multi core enhancement for a few days and XMP.
I just use NiceHash in windows for the mining. I’m sorry I totally should have specified.
Also, now that you mention OS, one of the BSODs I got was KERNEL_SECURITY_CHECK_ERROR (I only remember it because it one of the few I saw twice). If I can get into windows tomorrow I can try to get you more information about the crashes

Could you recommend me a memory testing program to try if i can get into windows?

The one I remember is memtest86 which should in theory be part of windows. I’m out of date though I’m afraid
