Hey all, had a customer of mine bring his pc in today with an odd issue. He uses the pc for some special software used to map together very large images at high res of massive landscapes taken from a plane and produce a 3d landscape image(or something like that, I'm not 100% sure of the details) it runs for a few hours a day endless at 100% CPU usage. Very CPU heavy workload. Absolutely no gaming is done on this pc and NO overclocking aside from xmp enabled for memory if that counts as an oc. It's an x99 build, specs are:
Asus x99-A
i7 5960x stock settings
32gb corsair lpx 2400mhz
Gtx 980 strix
500gb Samsung Evo
2TB seagate cheap drive
Evga g2 750watt
Corsair 100i
Cheapo tplink wifi card
It's been working fine for the past 2 months but today he had an issue. The pc wasn't staying on, it would load up windows then power off. He said it stayed on for 3 hours today then shut off and he was doing nothing heavy on it, just browsing the web. Very light use. After 2 minutes it auto turned itself on. Naturally I thought the psu had gone bad. I gave it a quick test with a psu tester and voltages were all fine. I then hooked the pc up with a test psu I have laying around and ran some prime95 for a little while. Temps were beautiful topping out below 60c CPU running full tilt. Pc did not shut off. I am currently running windows mem test and so far no errors but it did freeze for a minute while running the test, then carried on still showing no errors. Theres no post code that I've caught yet as with my test psu it's booting everytime no problem. Any ideas guys? He needs the pc back ASAP for his business. I'm really not sure what to tell him. Could it be the psu? I'm planning to leave it on overnight with hwinfo open so if it restarts ill know. Any ideas would be great thanks all!
