Fatheed 10 Posted June 8, 2013 So, I recently came across a pretty serious problem whilst playing Arma 3 with friends. I can fire the RPG no problem without the scope/sights, but as soon as I use it with the scope......my PC immediately powers off. This happens with no other game. I can play Arma 2 for hours on end or Arma 3 WITHOUT the RPG with no problems at all. I've ran stress tests on all parts of my machine for long periods of time with no problem. This really has me baffled. Apologies for the video quality but, for obvious reasons, I had to record it using my iPad. http://youtu.be/FRN1ImDgCuE Share this post Link to post Share on other sites
RuecanOnRails 10 Posted June 8, 2013 Hmm, that's an interesting problem. If I had to guess, I'd say your PSU is not delivering enough power to the gpu to render the explosion. What GPU and PSU do you have? You can check Event Viewer in custom views > Administrative Events to see if any sort of errors occurred before the crash. Because the computer literally powers off immediately, I don't think it's a software issue. Usually software issues cause a second or two of freeze then display a blue screen with the related error.

Fatheed 10 Posted June 9, 2013 GPU is GTX570 PSU is some generic POS 750w. The GPU should use any more power once it's at 100% load. It should just lower the FPS. The event viewer shows ID 41, Kernel-Power. I've ran test on all the normal causes of that and like I said, it only happens in ARMA 3. I've ran other games for hours without a single problem. I haven't entirely ruled out that it's the PSU but it doesn't make any sense >.< Share this post Link to post Share on other sites
RuecanOnRails 10 Posted June 9, 2013 A 750W should be more than powerful for a single card. A 750 can get away with a 3 card sli if you push it. One easy way to check the power supply is to do a cpu and gpu stress test at the same time. Use Prime95, and Furmark http://www.majorgeeks.com/files/details/furmark.html http://files.extremeoverclocking.com/file.php?f=103 Let those ramp up for a little bit, that should pull nearly max from your gpu, cpu, as well as testing the ram. You can try to move the GPU to a different PCIE 16x slot if you have a free one available. Perhaps it's something to do with the pcie slot? Of course, since it's only happening in Arma 3, it could be caused by arma 3. Try switching between the Dev build, and the Stable build. Have you tried verifying the game cache? perhaps try to re-download the entire game. Make a backup of your current install then allow steam to re-download. Worst thing could be not firing a rocket while looking down the scope ;) Share this post Link to post Share on other sites
Fatheed 10 Posted June 9, 2013 (edited) Well.......... Prime 95 runs no problem, but FurMark causes the same problem almost immediately....which is slighty worrying. However, I can run other tools like MSI Kombustor no problem. Edited June 9, 2013 by Fatheed Share this post Link to post Share on other sites
RuecanOnRails 10 Posted June 9, 2013 worrying, perhaps. But closer to a solution :) Now that we know the problem is caused when the gpu is under full load we can begin troubleshooting to find the exact problem. Try moving the GPU to a different slot and ensuring the 6 pin power cables are fully plugged into the card, and the power supply. If you motherboard has a 6 pin power connector beside the PCI slots, make sure you have one plugged in. it's used as an auxiliary power source when the pci slots are put under stress. The GPU can pull an additional 75W from the slot itself. Share this post Link to post Share on other sites
Fatheed 10 Posted June 9, 2013 Alas, I only have one PCIE 16x slot. The GPU already has 2 6 pins connected and the mobo also has a 6 pin connected. It can't be ruled out that it's the GPU but I'm leaning towards the PSU being the problem cos it's some generic piece of shit. Share this post Link to post Share on other sites
RuecanOnRails 10 Posted June 9, 2013 You might be able to ignore the problem, as long as it's only happening with RPG's while looking through the scope. Might change with Beta and the 3D Scopes. If you can get a hold of another PSU to test, it might be worth checking before buying a new one. You could also try to install your gpu into another computer and see if it works there. If you have a pcie 1x to 16x or some other riser laying around (probably unlikely) You can hook the gpu into any PCI/E slot. It won't offer the maximum bandwidth but for testing purposes you could still stress and cause the gpu to pull max power. If you decide to look into getting a new power supply, check with Jonny Guru's reviews.
