The system needs several tries to start up.
Hey everyone, I'm facing a problem when my computer boots. It keeps trying several times before it actually starts. Fans, hard drives, and lights all come on, but it just powers off after 1 to 2 seconds. This happens 1 to 5 times before it works properly. Once it boots, everything functions normally. I ran a stress test for about an hour using an Intel XTU and didn’t see any issues. CPU temperatures were around 26°C when idle and 66°C under load. The motherboard has two EPS 8-pin connectors, but my PSU only has one. Most people say the second connector isn’t needed. I’ve used: CPU i7 7700k, RAM 2x 8GB Mushkin blackline, GPU Gigabyte Radeon R9 290 Antec high current gamer 750W, PSU and GPU from my old build. The PSU is nearly 5 years old and the GPU about 3 years. Only the RAM, motherboard, keyboard, mouse, and monitor are brand new. I updated the BIOS, cleared CMOS, and booted with just essentials—SSD, keyboard, mouse, and monitor. Any suggestions would be super helpful. Thanks!
Just an update, I tired using the onboard GPU, 1 stick of RAM and remove the ASUS wifi card, removed the GPU. Its a bit more stable. Takes 0-1 attempts to boot up vs the 1-5 before, but issue still happening pretty consistently. @Septimus I was thinking it might have been related to the second EPS plug not being plugged in originally until pretty much 100% of people I've seen/asked and found online said it wasn't required. I don't know if it matters but this is the same PSU I used before upgrading. I was running i7 2600k Asus P8P67 deluxe mb 2x 4gb corsair vengeance ram. rest of the components were identical and I had no issues, and was running fine before I took apart that computer and rebuilt with new parts. @WereCat what do you mean by training RAM?
If you have another power supply unit available, I'd test it out. This might seem unusual, but I'm assuming the problem lies with the external power source—try connecting it to a closer outlet or another one in your home. You probably won't notice a change, but if you're stuck, that could be the solution.
I’d also check that every wire is tidy and organized. It’s possible a small part of the motherboard is touching something it shouldn’t, which might be leading to issues.
Sorry to hear you're having trouble. I relocated the device to another outlet in the same room without any problems. If the issue was power-related, it likely affected your previous setup too, but everything functioned perfectly. I inspected the wiring to ensure nothing was loose or touching the motherboard. Just a note—new update: after installing the second RAM stick and the Asus PCE-ac68 Wi-Fi card, it restarted 3-4 times before booting up again. It's still using the onboard GPU while the dedicated one is out.
Did you test it using only the second stick of RAM? Was the BIOS setup complete?
I noticed similar problems. I haven’t tested just the second stick of RAM yet—I’ll give it another shot and inspect the slots. Apart from updating the BIOS, I didn’t make any changes in the BIOS settings. It’s unclear what to look for there. I might need a new PSU tomorrow if I can spot one on sale. We’ll find out how it goes.
