Help. Cant identify problem. Pc wont boot.

[RicHaj]

Apologies If this ia short on information. Um having to use my phone.

Recently my Pc was randomly rebooting. Its been a while since i gave It a cleaning, so i dusted It and the problem was gone.

Reseated the ram, and the gpu no problems since.

Today se had a Power outage, and now the Pc wont fully boot.

ALL fans spins. All case lights turn. No beeps. Also no vídeo and the keyboard and mouse wont power.

I haver a pretty good psu a seasonic that IS even more than my Pc requires. Its clean, and Its been working fine. I Sidney skimp on that when i put the Pc together.

I took the psu out, cleaned It Just to bem site, plug everything back in. No change.

Also i have surge protection on this Pc on the outlet especially to Prevent these surges. Other eletronics seem Fine.

Pc is a bit old, 6 years now. Bit the componentes are solid and well kept.

I Heard tbat sometimes after Power surges the eletrocity on the outlet may not be fully stable for a while which makes the Pc not Power UP properly Until It does... in which case Just waiting sometimes fixes the issue. Could this be It?

Both my psu and gpu are the types where the fan only turns when under load. And even after letting the whole thing powered for Just about half an hour there ia no excessive heat noise or beeps.

Im at a loss here. Any help would be great.

If you have a decent power surge like you said you have then you should normally be fine.  This has to be pure bad luck.  Does the motherboard green light come on at all ?

Just an update in case anybody had the same problem.

 

Eventually i disconnected the 12Pin from the Mobo, gave it a few minutes with the PSU also disconnected. And it worked. Seems fine ever since.
