Problem with sapphire r9 270x

[zaius]

Yesterday my screen suddenly turned grey and since then the computer starts up but not the operating system, the issue is the graphics because with the integrated one and another old one I have it works perfectly, I noticed that when I turn on the computer the two fans on the heatsink start spinning but one stops almost immediately, has anyone else had the same problem? should I go and buy another graphics card?

I wouldn't rule out the source.
Try in any case with a LiveCD of a Linux distro you like, to see how it goes.

It wouldn't be bad to know what hardware configuration we're talking about.

@whoololon with a live cd I already tried it and it didn't boot either, the problem to find out if it's the power supply is that I don't have another graphics card that needs extra power.
My configuration is
I5 4570
Msi h87 g41
Amd r9 270x
Power supply corsair vx 550
8gb of ram Kingston hyper x

I tried to test it by disabling the integrated one in the BIOS, or by putting the graphics card in the second slot, but it looks bad :track_next:

It's slot I don't think it's because with another card it works, what I can't check are the pci-e connectors

[whoololon]

@zaius If the card you've tested requires extra power and works, then it may indeed be that the card has died.
If on the other hand it's one of those that only feed from the PCIe slot, then we still can't rule out that it's a power supply fault.
Fassou was referring to connecting it to the other PCIe 16 slot (the blue ones).

I didn't quite understand your last post.

I mean that it's not because of the pci-e slot because the other graphics card does work in the same slot, the only possibility apart from the graphics card being broken is the pci-e connectors, but I don't know how to check them as I don't have another graphics card to hand to test them

[zaius]

Now I have my doubts about whether it could be the source, because it has already happened to me a couple of times, including right now, that my computer has suddenly turned off and turned back on, the source is from 2009 so well, it gives me something to think about.

I can enter the bios and I get color bars

[whoololon]

@zaius If you have OC, restore the default values.
Pass the MemTest.

PD: If the computer is under warranty, make use of it.

[zaius]

@whoololon You don't have OC, and well the problem is in the graphics card, because you change it and everything goes perfect, the mystery is the graphics card doesn't work because of power supply or it's because it's broken, and unfortunately it's out of warranty, the computer is going to be 3 years old

@zaius Those "artifacts" in the colors look like they're from the graphics memory...

[zaius]

I have checked the voltages in the BIOS that the power supply is providing and they seem normal, would this rule out that the power supply has fried the graphics card? I had a gtx 260 die a while ago using the same power supply, a corsair vx 550 that I have been using since 2009.

[Fassou]

Those values are at rest, so you know they are not rare by hand, but you still do not know what it does under load.

If the source is from 2009, and the board and graphics were new, but another graphics card had already died on another board with that same source.

So mini point for the source.

[zaius]

These are the values I obtained with the CPU at 100% I don't see any strange values

You have already answered yourself, with the CPU, not with the graphics...
If what you want is to stress the power supply, download the 3DMark or the burnIn Test or something that makes all components work at 100%, not just the CPU, since to give you an idea, an i7 can consume 100W, but a graphics card can consume 200W.

The thing is that with the broken graphics card, neither Windows nor Ubuntu starts up, I can't use any benchmark
