Some motherboards stopped working and then resumed functioning unexpectedly
i had three defective motherboards: AS-H91HDS, Wibtek H61m-PCI2 and a H87-G43 gaming board. the wibtek H61m worked well after cleaning, but it shut down quickly after a few minutes. i tested it on several psus with different cpus and ram. after cleaning, it stopped working again, so i left it on my desk for about two weeks. yesterday i checked again and it kept running for a few hours during a stress test. the H91HDS board wasn’t showing up at first but worked after a week. i decided to retest it, and it booted perfectly! the H87-G43 didn’t stay on long—usually it drops after just a couple minutes, even if it does briefly. i left it for about a day and then tried again after the H91HDS board started working. anyone have similar experiences? what might have caused this unexpected fix?
I believe the chips required a significant amount of charge to be removed, especially after being powered off for an extended period. However, I'm not entirely confident about this.
