So I've just built a PC with the following specs
HDD WD Blue 1TB 7200rpm 64MB SATA
Intel® CoreTM i5-4460%2C 3.2GHz Haswell
8GB Kingston HyperX BEAST
Gigabyte B85M-D3H motherboard
EVGA NVIDIA GeForce GTX 660 SC 2048MB
The problems with this PC started after a few minutes of playing CoD Ghosts when it froze. I restarted the PC and it said that there was no bootable device found. I opened the case and reconnected the HDD cables. I turned it on and it worked perfectly fine. I decided to run WD LifeGuard and it passed the Quick test. Then I ran 3DMark Professional and after a few minutes of benchmarking it froze again. I restarted it and the problem with "no bootable device found" was present again. I turned it off for a few minutes and after I turned it on it worked fine.
What do you think it's the problem.
Thank you in advance.
