ASUS Tuf Z590 Plus Wi-Fi becomes stuck in a loop without any restart.
ASUS Tuf Z590 Plus Wi-Fi becomes stuck in a loop without any restart.
My new PC functioned properly for a week without any attempts to push it beyond its limits. I never tried overclocking it. Last night I stepped out to grab a drink and upon returning, noticed the machine repeatedly powered on and off. The red indicator on the CPU Q-LED also briefly lit up during this cycle. Initially, I attempted to reset the CMOS. Then I disassembled everything except the CPU, but the loop persisted. After disconnecting both the 8-pin and 4-pin power connectors from the motherboard, the system started up and remained active without any shutdown. Removing the CMOS battery overnight didn’t resolve the issue either. I then used the PSU jumper to bypass the power supply, which turned on and the fan began running. I’m uncertain what to do next. I’ve reached out to ABS for guidance. I’m checking my surroundings for possible shorts on the motherboard or damaged components in a USB port—similar problems occurred with a previous PC where the USB port failed and caused a looping condition. I haven’t identified any obvious shorts. Could my CPU or motherboard have simply stopped working? Given the short time frame, I’m still trying to figure this out. A video of the problem is available here: Specs – CPU: Intel Core i7-11700K Rocket Lake 3.6GHz (5.0GHz Turbo), 8-Core 16-Thread GPU: ASUS TUF Gaming GeForce RTX 3080TI OC Edition, Motherboard: ASUS TUF Gaming Z590 Plus WIFI, ATX, RAM: G.Skill TridentZ RGB 32GB DDR4 3200MHz (2x16GB), SSD: 1TB Gigabyte AORUS Gen4 M.2 NVMe, CPU Cooler: EVGA CLC 360MM RGB AIO, PSU: EVGA SuperNOVA 850 G+, 80 Plus Gold 850W, Fully Modular Case: ASUS TUF Gaming GT501 Mid-Tower.
You only had it for a week or less and it was a ready-made system you didn’t assemble. I’d just back up your data from the storage and swap it in with a new one. Although it might be fixable once the cause is identified, replacing everything could prevent future issues. If you built it yourself and can’t replace it fully, I’d check for a refund or replacement specifically for the motherboard to see if the problem continues.
