HELP! Benchmark crashes

[DWPDWPDWP]

Hello, I'll keep this short. 

 

I run Furmark, and as I hit the button to start the bench mark the computer suffers total power loss. 

 

I also get this when I load some games up. GTA, BF4 etc.

 

However when I run other bench marking software and play other games the computer performs flawlessly. 

 

No idea whats wrong.

 

I have tried MEMtest, Reinstalling windows, older drivers for GPU, disabling cf. All have had no effect. Nothing is overclocked also. 

 

Hardware/software.

 

CPU: i5 3570k,

GPU: R9 290 in cf

Mobo: Asus P8z77 Deluxe,

RAM: 16GB corsair vengance

OS: Win 10 64

 

Any advice is really appreciated as I am at a total loss.

I think the culprit is missing in your list... The PSU not able to provide the power needed to fire your system under full load.

It is a few years old, but has never been near capacity. I don't have a spare to test, so would have to purchase to find out if this fixes the problem. Also Furmark and other games use to run completely fine. 

 

Is there anything else you think could cause the issue?

Above you said it happens when you start the furmark benchmark.

 

Another issue could be the GFX Card failing.

 

But to get back at the PSU, I had a cooler master 520 watts psu that I used about 8 years. No problems at all. Then from one day to another my system got unstable under load. bluescreens, just rebooting etc... PSUs do age and after some time they can't provide the power they are supposed to reach.

 

I swapped it out with a new V550 and all was fine. Now I use that old psu in a system that uses max 150 watts and all is fine...

I've seen PSU fail after 3 weeks. Great job Thermaltake.

 

Do you live in US? Go to a Geek Squad and have them test it.

Sadly not in this case. I will purchase a new PSU tomorrow and test, if it doesn't work I will report back. 

 

Thanks for your help guys.
