Bob123 Posted September 5, 2019 Share Posted September 5, 2019 So I have a TB85 motherboard. Board looks brand new except that I found one bent pin. I bent that pin back into place and the board fired right up. I installed an OS on the system and I think it rebooted a few times during install (which is normal) then I shut the system down for the evening. The next day I went to turn it on and it refused to turn on. I took it all apart, messed with the bent pin, put it back together and it booted right back up again. Went to reboot it and it wouldn't reboot. So I shelved it for a while. Took it back out a few weeks ago and sure enough it booted right up. But refused to boot a second time. I had to swap CPUs for another reason. Tried to boot it up and it booted right up. Tried a second time and nothing. Today I wanted to test some memory so I decided to give this board a try. Booted right up. Ran memtest for several hours. Shut it down. Tried to boot it back up and nothing. So finally the question... Any thoughts? Things we can rule out: Tried multiple power supplies so I know it's not that. Multiple CPUs so I know it's not that. Because of the multiple CPUs I'm thinking it's not the bent pin. Specially because I've had it boot with the same CPU in it after leaving it for weeks. I also have had several brands / sizes of memory in it so it's not that. I've had a sata hard drive attached to it once without issue and memtest today was just on a thumb drive. I've also gone through and tested / shorted every capacitor thinking one of those are holding a charge when it shouldn't be. I'm at a loss. I guarantee if I let it sit for a few days, it'll boot right up. But I can't get it to boot up anymore today. Anyone ever have this problem before or know of any forums better suited for a question like this? Sure I could just toss the board and get another one but that's not the point here. Thanks.
