I need to completely test my graphics card

[Tunnah]

I think there's something wrong with my graphics card.

It started the other day, I noticed games were stuttering unless I had aero theme turned on (weird), and when I woke up today the screen wouldn't come on, so I hard rebooted. Upon trying a few things the system locked up then went to a black screen with just the mouse cursor, and CAD wouldn't work.

Now the system freezes up when I start GPU-Z, so I'm after an app that will test the graphics card, not just its rendering ability but also the memory etc.

I recently bought a new stick of RAM, about a month ago, and it could also possibly be that, I'ma run memtest86 at weekend when I get a memory stick (I used to have loads! Can't find a bugger anywhere though), but I don't know what would be best to test the graphics card.

If it is the card I'm glad it's happening now, the warranty is up this Summer, and that would suck if it happened after that.

I hope it's not though, I've got 2 Asus GTX 670s and one is already being repaired...gone 15 years using Asus without ever having a dodgy part, now I might have 2 of the same, ha

Did you add the memory stick or replace it? First thing I tend to look at is recent system changes, so if you added the RAM, remove it and see if the problem goes away. If it was a swap, then reverse it if you can and test the system.

Try a clean install of drivers. You could also test the potentially faulty card in another system and see if the problem is replicable. If that system starts acting up too, then you've found the problem.

A bit of both. One died, it was returned to Micro Direct who went out of business and nicked my RAM, so there hasn't been a stick in there for a while. It's ran fine for a few weeks now so although it actually seems like it is more likely the RAM I'm kinda hoping it's the GPU ha.

Also this problem isn't a constant/replicable, it's intermittent (no problems in fact since I made this post and I've been playing various games for the past 10 hours or so), so the RAM test will have to wait until weekend when I can run memtest86

Funnily enough it's a clean system - I reinstalled windows when I got the RAM, it felt like the right time, it'd been over 2 years since I last done it. All drivers are the newest and the only ones (apart from graphics card, that got the GTA V game ready drivers updated).

I appreciate the ideas fellas but I'm specifically after an app to test the card If the system plays up more and it becomes something I can reproduce then I can go the routes you mention but it's intermittent appearance makes it tricky

Is there no app that will stress test the card ?

[peterb]

Probably a bitcoin miner! But I'm not aware of anything to specifically test a card. But others might!

I assume furmark is still available? That used to be the go to tool for stressing a graphics card, although it got a lot harder when both NV and AMD introduced advanced power management....

[satrow]

Yes, Furmark is still pretty much the standard graphics tester - don't leave it unattended though, it can trigger a lot of heat. From memory, a 10-15 minute run is all that's needed to get a solid idea of the stability of a card, any weaknesses are likely to show up a lot sooner than that.

IIRC from using Furmark to test OC on GPU it doesn't load up the RAM that much.

To test RAM OC I think I used games last time.

Subscribed to thread to perhaps learn if there's something new out there!
