Need help with random PC shutdowns?
Hi Guys,
Here’s a summary of my setup:
I have an Amd Fx 8350 with automatic overclock to 4.2, paired with an MSI 970 Gaming motherboard.
The system runs on a Sapphire Tri X R9 290 with 16 GB 2133 MHz GSKILL Trident memory.
I use a Crucial SSD 250GB B100 as the primary drive and a Western Digital Black 1TB as secondary storage.
My power supply is a Cooler Master V 750W Gold Series unit, and I have a Noctua NH-U14S single tower CPU cooler with a push-pull fan configuration.
The case I’m using is an Enthoo Pro with seven Corsair AIr fans.
This was my first PC assembly about a year ago. I managed to overclock it to 4.3 manually, but since it was my first build, I didn’t push further and switched to OC Genie for automatic overclocking to 4.2 GHz, adjusting only the DRAM frequency from the default 1600 to 2133 MHz.
The system worked well until three days ago, when a YouTube video caused it to shut down unexpectedly. I thought it might be a software problem, restarted it, and it worked again—only briefly.
The next day it crashed again, I tried rebooting but the OS wouldn’t load and it shut down. After three attempts, it finally started but only ran for about ten minutes.
To be honest, I didn’t know what was wrong. I cleaned the PC thoroughly, replaced the CMOS battery, reinstalled the OS after a full format and DOS clean (Windows 8.1 Pro), checked temperatures with HW Monitor and CPU Z, removed and reinserted RAM, and tried different settings.
The PC stays on for around 30 minutes before shutting down. If I reboot it after ten minutes, it boots but crashes at the Windows login screen. On BIOS, it stays on indefinitely.
If I turn it on after about ten minutes, it boots and remains active for only five minutes.
The CPU temperatures during medium load are around 28–34°C, and the GPU is about 40–44°C idle. All fans run at 40%-50% capacity.
I’ve read many people mentioning the PSU, but I thought it was fine. Recently I turned off overclocking and set DRAM to the default 1600 MHz, then restarted Windows. It didn’t load at all, and even after a few minutes of overclocking it would crash.
It seems the default settings work, but overclocking causes instability.
I’m not sure what’s happening. Any advice would be greatly appreciated.
Thanks.
never increase performance beyond recommended limits, disable oc genie and adjust bios settings to default.
You should never increase the clock speed of any software. Disable OC Genie, reset all settings back to their original state—including DRAM frequency to the default of 1600 MHz—and then restart. It seems that even with the default configuration, Windows will close immediately upon login. I understand this might sound strange, but if you overclock, the system only runs for a short time (about 5 minutes) before shutting down. This confusion is why I’m not sure what’s happening.
Thanks guys. .i just tried the ram first. I removed 1 stick and tried to boot so that i can go into bios and change all to default and then insert the second stick for boot up.
But now there is no display..my graphics card fans are running but no display..even on dvi (monitor) and hdmi (Tv).
I tried inserting both the rams but still same result no display.
This might be a noob question but i have had this running for past 1 year with no problems and now suddenly all hell lose. .if only i could figure out which component is at fault. Now even my graphics card won't work is it faulty now because of the random shutdowns? I am sorry i don't have a spare psu to check.
The motherboard lacks built-in graphics, meaning it doesn't have any ports for connecting its own graphics components.
You should also consider using a board that includes onboard graphics, just in case the GPU doesn't work in a new build.
I don't understand how far I can go to get the board. However, I've noticed something now... my PC doesn't produce any beep sounds. Even with all RAM sticks and an HDD, the SSD removed still doesn't make any noise. I have no idea if the post is working. I thought about getting a BIOS post speaker and trying to connect it to the motherboard. If that doesn't work, I can be sure it's the motherboard. Any suggestions? Also, my GPU has three fans, only the outer ones should spin and not the central one — it should start spinning only if I reach 60°C. But when I turn on all the fans, it spins up on my GPU. Is there something wrong with the GPU?
