Okay so about a week ago i cleaned my computer with air blower.

I took out graphic card,rams,processor,processor fan and i cleaned it all and put back CORRECTLY.

Now all of a sudden i get black screen on monitor and idk how to fix it. My graphics card doesnt work on primary slot (X16) anymore (even fans dont turn) but when i put it in secondary slot (x4) fans are working. I really dont know what the problem is i took computer to my FRIEND to let him fix it and he told me its probably motherboard/processor problem. I really dont think its processor problem to be honest more like motherboard. Idk maybe a little water got on motherboard and it fried it or something. I would really want to get professional opinion before i go risk buying new parts that ACTUALLY work fine. I would appreaciate any help if possible.

Thank you for your time and have a nice DAY! Well, IMHO, you can not fix it.

Yeah im pretty sure you can't fix it but idk what is causing this issue. Processor or motherboard, what do u think? probably gonna have buy new specs so i wanna be 100% sure whats causing the issue so i can replace it with new stuffNo, the CPU is alright.
Believe me.
Get a mew mother the takes that CPU and ...
- do NOT try to use that graphics card again.
Why not? So that means ill have to buy new graphics card too... sounds like a slot in the motherboard is bad.Quote
