Been struggling and trying to diagnose for a while, any help would be appreciated as long since lost my knowledge (since having kids and no time!).

Running a (I know its old but its what I have):

ASUS P8z68-VPro
Intel Core i7-2600K - no longer overclocked
8GB RAM
Radeon R9 200 series (on 3 monitors as individual screens, and the on-board doing a 4th screen)
1TB SDD
250GB Backup HDD
Windows 10 X64

A while back it was just shutting off randomly, did all the usuall, full re-install of windows, updated all drivers etc. Replaced RAM as thought this could be the issue, no change. Eventually thought it was my main and spare HDD so replaced with a SDD and a new small spare HDD, which seemed to improve it. I was only ever using it for web browsing, emails, watching movies etc.

Now, my boy wants to play games on his XBOX when he is with his Mum, and I wanted to be able to join him, but when I try, it works for a bit then dies, no warning, just shuts off - so seems its when its under load from the game (only playing on 1 screen). Leads me to think its the 600W PSU but unsure how to test (read the sticky and will probably just have to get another as it was beyond me).

The route quesiton is, is the spec I have likely to strain a 600W PSU (which is quite old) and if so, what should I replace it with?

Many thanks
 
Its an OCZ 600W if thats any help, probably over 10 years old

I just tried playing with only 1 monitor connected, and same thing. When I had more Hdds in the case it was doing it with normal use, so I am thinking the more power it draws, then it trips out. Any recommendations for a PSU, cant spend too much, so £75 max, unless there is a really good deal out there?

Which is better, Corsair, Seasonic or Kolink from Overclockers?

yes, temperatures seem fine for the CPU and GPU, nothing spikes really high, I am not really stressing the system like I used to when I used to game. I tried disconnecting everything but the essential and still seemed the same, apart from when I disconnected additional HDDs

Just been trying again, CPU got to 86C on core 4, 82-85 on others, GPU 82C

Think they got upto 88C on CPU and 87 on GPU before shutoff again?

Did a CPU stress test and it got to 88C, a GPU stress test and went to 94C - seperately they ran fine and stabilised. Not tried to run them together. Bed now, will look again in the morning. Thanks all.

Took the computer outside and blew it out, fair bit of dust and temps are a bit better. Will give it another go later and see if its helped with the gaming, saves about 4-5 degs in the stress testing.

Tested this evening - 1 random shutdown whilst playing....done everything I can, now will wait on the PSU.

so, new PSU in, no difference. Tried Prime95, seems to crash earlier now but temps are good. Have tested the RAM, thats ok, now trying it with the onboard graphics (which I use for a 4th screen) disabled as in the last crash it went all wierd so though that may be an indication and it now seems to last longer (upto 10 mins now and still going). Running out of ideas (and money), hope this works!!!

@freddie64 - will give it a go
@GaryTheSnail - I did a gresh install of everything, updated it all etc etc when I put in new SDD, and several other times. If its a software problem I wouldnt know how to narrow it down other than running the absolute minimum, which I have tried. It may be as simple as my hardware is really old and drivers are lacking, unsure how to find out

Ps - thanks for the ideas

trying to rememeber all I knew from my overclocking days years ago - Prime95 and the like. Running on smallest FFTs, 100% load, doesnt last long, am going to compare with 4th monitor and without and see if I can narrow that concern down
 
update - worked without a problem with 4th monitor off, then tried again with 4th monitor on and it shut off during the 1st game, any ideas what could cause it?

But - it fails in Prime95 before 5 mins running on any test but the temps dont seem to get excessive - will take apart over the weekend and re-do the thermal paste on the CPU and see if that helps at all.

Which thermal paste should I buy - dont recognise any of them anymore?
