hi guys, 15th may my pc suddenly went blue screen while playing the game, then i did reboot pc and somehow my boot sector was damaged
after i tried to boot secure mode, monitor goes black, but pc itself continued to run ( coolers, leds and etc)
after restarting again , pc starts, speaker do 1 short signal, but doesn’t boot at all , keyboard led is not working
after this i’ve tried to reinsert CMOS battery, RAM, CPU, power cables, and i noticed that if i unplug my graphic card, speaker doing 1 short signal, my keyboard led is working and then do 1 long and 3 short signals which telling about no video
also tried another RAM, it didn’t make any effect
2 days ago i did clean whole gpu and applied new thermal paste, then after it my pc did boot up normally and i could restore windows boot sector and load to system
after this i noticed that one of my hdd was corrupted or unreadable, didn’t pay attention to it, just fixed it with windows program and it did delete some files
yesterday pc was perfectly working
and today pc doesn’t boot up like it was 2-4 days ago
i will mention that this pc was build 3 years ago
only graphic card was in use more then 3 years (bought from hands), but it did worked good (no overheat, no frequency jumps)
my specs:
-CPU: Ryzen 2700
-Motherboard: Asus TUF b450m gaming plus AMI UEFI BIOS
-RAM: 8x2 Crucial CT8G4DFRA32A.M8FJ 8GB DDR4-3200 CL 22
- Graphic Card: ASUS Strix GTX 1070
-2 SSD: 1)Kingston A400 2) Crucial BX500
-1 HDD: 1)WD 1003FBYX
-PSU: Cougar VTE 600

How old is the PSU in your build? 3 years?

See if you can source(borrow, not buy) a reliably built PSU with at least 550W of power at the entire system's disposal and see if the system regains live.

thank you for replying
1)Yes, PSU is 3 years old
2) my brother will borrow me fully working PSU tomorrow
can’t understand what exactly causing the problems, because, in my opinion, if it was PSU side problem, how i would manage to boot pc yesterday
its very strange anyway

hi again
another working PSU did zero effect, pc still doesn’t want to boot up
i have assuming that is something wrong with my cpu or motherboard, because i checked every other specs, and they were fine on another pc
sometimes pc boot up when i do some manipulations with cpu like moving it in socket for a little bit, but can’t catch exact pattern of where i need to move it
