Ok', im in a bit of a pickle here. I build a pc for my friend from used components i bought, tested it and all works. He gets it, and it freezes - hard locks in games, screen goes gray or the image goes still and audio sound is like '''EERRRRRRRRRRRRRRR'', than you have to hard-restart it. I take it home, and i can barely make it crash, and it is tottaly random! I have been trying to reproduce it crashing so i can start troubleshooting but to no avail, in the 48h i have been tourchering it has crashed only 3 times. In bf4 twice, one time in singleplayer while just standing still and starring at screen, other time in multiplayer match in a helicopter, and once in GTA5 durring first tutoriall, i have been trying to make it do again but it just wont crash! I opened multiple games and benchmarks at the same time, on 2 monitors even, and nothing! I am burning it with prime95 and Fur mark to make it hot, and it is hot now, but nothing, it wont crash!
I was thinking maybe its PSU bit faulty, but since it holds up to burning stress testing.....
Specs:
Intel pentium g4600 (stock cooler)
Sapphire nitro RX 580 4G
Gigabyte ga-h110-d3a
Single stick 8gb ddr4 Kingston 2400 (in hw info its Clock is constantly fluctuating around 1066,1-1067,1, is that normal?)
Antec VP 500w
patriot burst 120g ssd+ wd 250gb hdd
4 cheap antec molex fans from antec case, i all put them on single molex power and stack it, was thinking that was doing the problems, but i can't reproduce the crash reliably to figure that out. It only randomly crashes sometimes in games, not in benchmarks stress testing (tried all unigine benchmarks, aida64 and furmark)
I allready did reinstall windows from scratch few months ago, test it it was fine, gave it to friend and than it crashes. Anyone have any idea what to do next except reinstall everything from scratch ? It looks like a software issue since hardware is holding up to stress testing. Temps are fine fine, gpu wont go above 62 and cpu above 60-70 durring haaard pushing with multiple games, only with prime95 and furmark i can get gpu to go up to 73 and cpu 95-100, with both prime and furmark running, cpu throttles to 3500/3600 from usuall 3700 when hitting 100.
Also the clocks of GPU seems a little low for 580, and it is awfully COOL (my personal 580 8gb is much hotter and louder than this one) and there is bios switch on gpu its on right position performance mode and getting only 1150 core and 2050 memory. I checked the sticker and it is real 580.
