PC Died (where do I start a post-mortem?)

[Ninco!]

Hi all,

I would be really grateful for some advice, my PC recently died and to be completely honest, I am not sure what was the cause? Unfortunately due to the lack of signs; neither am I sure how to go about fixing!

The issue came about, I was running Handbrake and the PC shut down, no sounds, literally, it was as if I turned off the power and placed my PC into Sleep. I tried to reboot and the only signs of life is that the LED for the power button is illuminated? The only other cause I can think, I used a powered dust cleaner about 7 days prior - I am not sure if this contributed (the PC was working fine for 5+ days after my cleaning effort?)

The fans do not switch on, no POST etc. I have a feeling the PSU blew? Although I always thought that when a PSU packed up, it would give a sign?

Without purchasing a replacement, I am clueless, no idea if this was the root cause? Unfortunately, I cannot 'borrow' a PSU so it will literally be a case of purchasing the part and hoping for the best.

I could contact the manufacturer, however, I purchased back in 2014, so outside warranty.

Many thanks,

Hi All,

Firstly, really appreciate you all taking the time to provide advice and help, thank you.

Sorry I should have posted spec's. To be fair to the manufacturer, warranty is five years (two years collect-and-return and parts, plus three years labour-only RTB) I purchased July 2014. I should give them a call, the idea of a courier faff, might be easier to drop off and collect?

Anyway, specs:

Processor Intel Core i5-4670K
Processor external bus 100MHz (DMI)
Processor multiplier x42
Processor clock speed 4.2GHz
Processor socket LGA1150
Memory 8
Memory type PC3-12800
Maximum memory 32GB
Motherboard Gigabyte GA-Z97X-SLI
Motherboard chipset Intel Z97
Hard disk model(s) Samsung 840 EVO 120GB + Seagate Barracuda ST1000DM003-1CH162
Interface SATA3

The power supply is a 500W model from FSP. Nvidia GeForce GTX 760 with 2GB of GDDR5 memory.

Apologies if this sounds naive, should I just call the manufacturer?

I have a horrible feeling it is a PSU or Motherboard failure, the thought of taking it all apart (I have postponed as its been a few years since I built a PC and not a task I would relish!)

Thanks again all.
