Hi, 2 days ago I let run my PC during the night. When I woke up, I found PC being very laggy (although no apps were running) so I hit restart button and since then I have serious problems with getting pass BIOS screen. Any problems whatsoever before, no recent HW changes.
I tried to unplug all unnesessary external port - nothing, tried reseating my 4 RAMs (one at the time, even different slots) and clearing CMOS multiple times, unplugging HDDs (I have 3 of them) or running one at the time. Even running PC with bare minimum to run BIOS (1xRam, GPU, CPU and keyboard) and nothing changed. When I start computer, all I see is black screen and when I hit restart button, BIOS welcome screen shows up. Sometimes I can press DEL for setup to see post BIOS message, showing my CPU, my RAM size with "OK" but it never gets into actual BIOS setup screen.
So I gave up yesterday, put all HW parts together, and started PC again and when I came back (5-15 min) it got pass BIOS. I could go to setup, restore it to its former state, and PC run whole day without any problems, even played games with it. Later that day after I left PC running alone just being idle once again after 8 hours since it came to life again I found it with BSOD.
Today I have been trying same stuff as before, only to see the problem is getting worse. Now, sometimes I cant see any BIOS screen - I have to try multiple times to get BIOS message, and even when I do, waiting even for 30 mins wont do anything this time to get me pass it.
Based on similar treads aside of obvious ones (disconnect all USBs) people are poiting to damaged HDD - but question is should I be able to get into bios setup without HDD, bc I think I would be just getting something like "cant find bootable device" ? then there is PSU but then again 1. I was able to run PC for 8h under heavy load without problems. 2. I replaced PSU for brand new just 4-5 months ago. RAM only if all 4 stick died simultaneously.
I really thought it was bad MOBO but why was I able to run PC again then ? Also, that would mean most expenses, so I wanna try something else.
So do I missing something ? Could it be just dying CMOS/MOBO 3V battery that making this weird stuff happening ?
