PC randomly stopped working

[ReggieKray]

So last night my computer randomly decided to stop working. I've looked around for solutions but nothing seems to work, so I decided to come to the place i know is one of the best at handling PCs.
After gaming for a couple hours last night, on a really hot day (30 degrees celsius in england), i left my computer on sleep and went to meet some friends and chill for a couple of hours. Upon returning i found that the PC had shut down itself. When I pressed the power button, the lights and the fans turned on for half a second and then turned off again. I thought it had overheated or something similar because I'm fairly new to PC building and the sort. I gave it time to cool, even opened it up, cleaned it and placed a fan facing towards the components. After 4 hours or so I tried to turn it on again, but nothing had changed. After looking through many posts on this site, I couldn't really understand what was being said, so I picked the two most basic solutions I could understand. I turned it on with RAM removed but the outcome was the same. Now I'm left with having to buy a new PSU. Is this the correct solution?
Specs:
FX-8320
MSI GTX 770
GIGABYTE motherboard that I forgot the name of
8GB Kingston HyperX DDR3
2TB HDD
Corsair 650W PSU

Also recently installed a new cpu cooler, a Cooler Master Hyper T4, about 3 weeks ago. But the PC has been working perfectly since then. No beeping can be heard.

If your corsair 650W is from the VS line, there is a good chance it is the culprit. The question afterward is did it take anything else with it.

TX650W

Information I've found on the TX650 say that Corsair have changed the OEM on these units. There have been like 5 different version of it, and apparently the latest version feature the Samxon GF caps which have a reputation of dying in hot temperature. So the most likely conclusion at this point is that your TX650 has died.

Now the question will be did it take anything else with it...

well, fk my life, just why me. In other news, I thank you sincerely for your effort and research. I now understand what has gone wrong thanks to you.

Lastly, any suggestions for a PSU that will run safely for the next couple of years? Perhaps a brand of PSU that the Tomshardware community trusts?
Thanks, Reggie

Seasonic is the brand that has unconditional trust of the majority of the community and prices of their PSUs certainly reflect this. Other makes/models from other brand that are also hold in high regards are EVGA's SuperNOVA G2, SuperNOVA P2, FSP's HYDRO G etc...

In your case, the FX-8320 would consume ~185W at stock, a heavy OC could increase power consumption up to 50% more; MSI GTX 770 should be at 260W; accounting for other hardwares + targeting the general top efficiency point at ~70% of the PSU max capacity and the result is 650W model of the above models/manufacturers for operation at stock clock, 750W version for overclocking.

EVGA SuperNOVA G2 650W : £87.15 @ CCLonline

FSP Group Hydro G 650W : £96.77 @ Amazon UK

Seasonic X650 : £129.21 @ CCLonline

The EVGA would be the best choice for you price-to-performance wise.

Did that fix your issue, I might have something similar happening to my computer...but it mostly happens when I try to play a game..sometimes doesn't even make it to the log in screen before the screen shuts off and my gpu starts spinning its fans at full speed
