Ok, second time writing this. First time my pc shut off in the middle of writing (more on that later).
So i decided to dust out my PC today. I like a nice clean pc and more airflow is better imo. I'm a pretty experienced system builder (used to work as a repair technician in a pc shop) so i'm pretty confident when it comes to disassembly and reassembly.
I took apart my pc and blew out all the dust using a balloon pump which has always been my go-to dusting tool due to its lack of static and reusability. After dusting everything out I put all my components back into my pc, i plugged it back into the wall and attached all my peripherals just as it was before i took it apart. I booted it up and after about 30 seconds on windows, the cursor froze and i got a back screen.
I started trouble shooting my problems by removing components (graphics card and non-essential drives) the best result i got was when my pc booted but my cpu was running at around 0.2 - 0.8 Ghz. After i had about 10 minutes of stability, i thought it would be a swell idea to come to the LTT forums to talk about my issue. Well like i said, half way through my writing, my pc flickered a black screen at me, and shut off. By this point i'd already come to the conclusion that my OCZ 550w psu from a few years ago had finally died. I think that my dusting may have caused this (oops). Either that or a motherboard fault, as unlikely as that would be, considering that the motherboard is the only part of my pc that i didn't remove. Is there anything i should be considering before going out and buying a new PSU?
I didn't post this in the power supply section of the forum because I'm honestly not 100% sure it's my PSU as likely as it might be.
Core i5-6500 at 3.2Ghz
8gb DDR4-2133 ram
Gainward Phoenix GTX 1070 Graphics card.
MSI Mortar b150m Motherboard.
OCZ Fatal1ty 550w 50+ White power supply (RIP)
TLDR; Computer machine broke, might be psu. What do?
