Hello everyone,

I got a peculiar problem when I'm using my computer casually where it suddenly become so lag then it automatically reboot. I checked Event viewer and got this status:

A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 1

The details view of this entry contains further information.

Several troubleshoots that I have tried including:
1. Memcheck from windows; All cleared on memory. No issues found, yet problem still pertained.
2. Unplug WiFi card & DDU re-install graphics driver. Issues still exists.
3. Format and re-install windows. Issue still exists.
4. set BIOS configuration to default including not choosing d.o.c.p RAM profiles.

As for my computer specification, specified in the following:
1. CPU: AMD Ryzen 5 3500x
2. Mobo: Asus PRIME A320M-K
3. Memory: V-Gen Tsunami DDR4 3200Mhz Dual-Channel 16GB
4. VGA: RX 580 8GB - Red Devil
5. Storage_1: Adata SX6000 Lite 256 GB M.2 NVME
6. Storage_2: WDC Blue SSD 500 GB
7. PSU: Infinity 500 W (80+ Bronze)

I have also run CPU Stress test using Prime95 and during self test 12K (````+/-30 min) it suddenly become lag and restarted itself. The temperature of the CPU at the moment reach 85 Celsius degree. 

Can someone help me with this issue? Does the problem lies on the CPU? (which means I need to RMA it) or Does the PSU is the problem source?

I'd really appreciate your kind help and fast response.

I noticed that a lot of people are having this issue at the same time, including a friend of mine which i'm trying to help. I wonder if Windows 10 update screwed up something?

Update, 

 I have tried stress testing using prime95 and take a log during stress testing with temperature readings from HWInfo64. Based on the logs, when the computer suddenly restart, the temperature of the CPU only reach 63 degree and the motherboard only reach 45 degree. I think it's safe to say that the temperature wasn't the case (the main cause of my computer issue).

[UPDATE]

It's already fix. It's turned out my electricity is not as stable as it used to. I changed the PSU to CM V750 2 which has greater efficiency and bigger capacity. I also bought an additional UPS to stabilize as well for risk mitigation should blackout suddenly happen. Ryzen cores are really sensitive to voltage changes.

How is your system running now all stable? with the supply change and UPS is it pure sine wave or simulated?
