Newly built pc freezes when gaming

[sybilmeows]

At the beginning of October, we had a pc built for gaming and from the start it's been freezing usually with a buzzing noise during gaming. It requires a hard restart, and sometimes we have to restart more than once. It's been back to the shop several times with no solution and they seem unwilling to help any further.

It freezes on various games - Sims 4, Witcher 3, XCOM, Civ BE, Mass Effect 3, World of Warplanes. It freezes anytime - during cinematics, on inventory screens, mid-combat, etc.

Here are the specs (from their bill):
Asus M5A97 R2.0 970 AM3+ 4D.DDR3 - ATX Motherboard
500 GB Crucial BX100 SSD SATA III
Asus Radeon R9 390 8 GB DDR5 PCI-E
700 Watts 80 Plus EPS 24/8 Active PFC Power Supply - Sparkle
Windows 10 Pro 64 bit

So far they've switched out the motherboard, the gpu, and tested the RAM. They are now telling us it's a Windows 10 problem and we'll just have to wait until Windows 10 is fixed. Oh, and I ran the Prime95 test yesterday for 10 hrs with no errors.

I've seen other posts with this problem, but none I don't think, with Windows 10. Do you think that's the problem? Or any other suggestions?

What is the model number of the PSU?

I think it's SPI700GHN

I also forgot to list the processor: AMD FX8320

Thanks so much.

I wonder if it is a PSU problem.

looking at the PSU specs, i am a little worried. I expected the 3.3V and 5V to have 20A to 25A and also to see four PCIe power connectors.

In addition, a Radeon R9-390 requires a 30A and a 600W PSU minimum. Dividing the Amps over the four 12V rails, might not provide enough amps to the video card when under high loads like playing games.

I was wondering about the PSU, because of what I read in other posts, but I didn't realize it's more complicated than just the watts. We'll try a different one. Are there any you would recommend?

Any of the tier1 or tier2 PSUs from this link would be a good choice.

Well, it's taken awhile but here's what happened: the shop put in my husbands gpu (an older AMD one, HD 9800, something like that) and the computer didn't freeze, so they got us a different psu (the EVGA 750 watt). It still freezes from time to time, but nowhere near as often as it did before. It seems totally random - except that it seems to happen only if the internet connection is active. So as long as my game doesn't require an internet connection to play, it's fine! Maybe Windows updates will fix it for good eventually....

I'm betting the psu was part of the problem, along with Windows or maybe even my antivirus somehow. So I'm going to mark my issue solved, thanks so much Emerald!
