Hi there, I have a problem with my computer (not sure if is the psu, cpu or mobo). A couple of weeks ago my computer started doing a cold double boot, that is when I turn on my computer (after turning on the psu) it reboots before or after the post (not sure, 2 seconds or so) and then when it boots I see the screen that it asks me to press F1 to enter setup (a factory reset, if I'm not mistaken).
Some days ago, I decided not to turn off the PSU to make sure it's not the cmos battery and it isn't, the computer has kept double booting (although not always happens, I can't tell if it's time related or what). After researching on google (and a couple of forums) I decided to tear it apart and clean the dust, and making sure everything is well connected (and that there are no shorts anywhere). I saw a couple of strange things in the rear:
1. A bit of a circuit is peeled, like a scratch but just the black (protective?) layer, the copper is visible but just for less than half an inch of the circuit (this is on the top edge).
2. Behind the armor, just on the other side of where the liquid cooling install block is, I can see how the board has a burnt-like color, though the solderings are just fine, that color had me worried. Tried cleaning it with alcohol (96%) but I wasn't able to clean it (didn't want to force the cotton).
I was using the computer before cleaning it, so it was on. After that, it happened again, I turned it on and it did reboot (doing a factory reset). Not sure if worth mentioning, but the anti-surge feature was triggered two times that day after reassembling the compter, does this have something to do with the PSU? If it's broken or has some damage (or maybe it was just the electricity, but it was only my computer what was shut down) how can I test it (the PSU)? I know seasonic offers many years of warranty so I just have to contact them.
The computer is more than 3yo and I've never had a problem. After it started happening, I decided to strictly configure UEFI, things like disabling features I don't need/want (fast boot, all related to legacy --CSM, USB-legacy, etc--, wifi/bluetooth adapter, secure boot --cleaning the keys and then selecting "other os"--, etc...). It bothers me that I have to re-configure everything every time it happens...
Does someone know where the problem might me? I don't know what more to try, can someone tell me what tests can I perform to try and find the problem? The specs are there under my username.
Thanks.
