Broken GPU?

[McPhee]

Every time I tried to load a game this evening, the system would lock up after a minute or two. A web search suggested reinstalling the GPU drivers. Upon reboot, there's no video output to my monitor. I've tried DVI and HDMI to my monitor, and HDMI to my TV.

Reasonable to assume the GPU is knackered? Or has anyone got an alternative idea? I bought it on the MM and don't have the receipt, so RMA is going to involve some leg work.

Could quite easily be the PSU is on its way out.

CPU stable?

Any other systems to test the card in?

just replaced my lads 750cx because of this ..

No spare video cards. But I do have a spare PSU. I'm not keen on using it though; it's a Sumvision unit of unknown age and very low quality that came free with a case ("600W", yet only 18A on the 12V rail...).

The whole system had been stable since it was built three months ago. The only recent changes have been the addition of four extra case fans and a new keyboard.

The PSU is a Corsair CX450M that was bought new back in April. It's driving a stock Ryzen 5 2600 and RX570, so it shouldn't be overloaded, but could be faulty. Got to start somewhere, so I've contacted the retailer and they've refunded the PSU and told me to keep the potentially broken one. I'll order a replacement today (or maybe nip up to OCUK and buy one).

I'm tempted to order a Vega 56 at the same time. For testing purposes, obviously

450w psu ?? why so low ? rx570 =300w max load ryzen 5 2600=345w max load .. then motherboard and bits and bobs ...
who told you to get a 450w ? minimum for that is 600w unless all your doing is surfing the net .. soon as you put a aaa title on your watts will shoot up ..
evga 650w psu is your best bet

You're joking, right? Those components won't draw anything close to 450W, let alone 600W. Where are you getting power draw of 300W for an RX570, and (even more bizarre) 345W for a R5 2600?

Also confused as to why you'd say 600W minimum, 650W recommended if you think system power draw is as high as you say. Surely if it's 345W for the CPU + 300W for the GPU + the rest of the system, your minimum recommendation would be a 750W unit?

hes wrong on draw but right on that your likely running that psu way outside of its efficiency curve. 450w also doesn't mean 450w continuous draw. What power supply is it? I ran a Kolink ML at its max rated draw for 3 weeks and melted it (380w) from a 450 unit so regardless I wouldn't be suprised if it was the PSU, looks easily the most likely right now.

RX570 - TDP 120W but ive seen peak power draw on that card at 200w/225w.
r5 2600 - At full load it breaches its 65w tdp mostly and draws around 80w

So with just 2 components under a gaming load your somewhere around 280w with just 2 components.... Not saying it is the PSU but jesus man test a different one

My current PSU is a CX450M. It's rated for 448.8W on the 12V rail, with peak efficiency falling between 60% and 75% of rated output (so 270W to 337W). Peak draw from the system should be around 320W, going by reviews for the various components, plus user testing, plus Outervision's calculator. The PSU should be operating around peak efficiency under gaming load, and certainly shouldn't be overloaded. Broken is, however, a distinct possibility.

I've ordered an SF600 Gold to replace it. When I built this PC, it was a tentative step back in to PC building; I did it on a tight budget and bought parts for their value rather than their performance. I'm now itching to build something better (smaller, faster). The SF600 Gold will carry over nicely to my next project.

I'm not reluctant to test a different PSU. I'm just reluctant to put this anywhere near my main PC:

And I don't have anything else to use until the SF600 arrives tomorrow.

pulled up the wrong dbase .. that's total for the system on both .. .. some days just go wrong and you(I) have to admit FAIL ..

So here's a twist; I've just got the system to boot.

Currently running tests to see if I can find out what went wrong yesterday.

EDIT: Everything seems... fine. Tried a few benchmarks. Played a bit of FH4. No stability issues. No temperature problems. Whatever went wrong yesterday, it's seemingly resolved...

The old magic fix itself shenanigans Love that!

And... broken again.

Display went blank while playing Kingdom Come. Rebooted, and it went again before I got to the game menu. Tried again now and got the same thing.

Will get a new PSU and a new GPU ordered now as one or the other is the likely culprate.
