PC Freezes while gaming, browsing web, no response from mouse or keyboard ??

[ChrissyDoc1888]

my pc keeps freezing while gaming, browsing web, no response from mouse or keyboard, happens almost daily, have to reboot it for it work again and dont get a crash log etc.

PC SPECS :

MOBO : GIGABYTE GA-990X SLI
CPU : AMD 8320 BLACK EDITION : 3.5GHZ(not oc'd)
PSU : AEROCOOL INTERGRATOR 700W 80+ BRONZE
GRAPHICS : MSI GTX 1050ti 4Gb
RAM : 8GB HYPER X 1866MHZ
CPU COOLER : BE QUIET PURE ROCK
CASE HAS 5 FANS 1 EXHAUST, 2 TOP MOUNT AND 2 FRONT MOUNT

While you could have problems in your video drivers or MB VRMs, your power supply is highly suspect. The reviews I have seen for Aerocool were kind to the brand on price. Ripple control was listed as an issue. Some of the opinions of the brand on Tom's forum use the word "junk"

A Tier one or two psu would be recommended.

Nice one ill have a look into this, i thought if it was psu it would just shut the computer down, i have checked for video drivers there all up to date as with mobo vrm ill have a look into that in the morning never looked into that before

As for the VRMs, on some motherboards, you may need additional cooling put directly on the VRMs for stability. Would setup fans to exhaust from top if not done already (heat naturally rises) Bundle cables for smooth airflow, etc.

I'm assuming you already checked your motherboard manufacturer for RAM compatability, something else that can cause the symptoms you stated. My apologies for not including that earlier. If using an XMP profile, bumping down to stock may be helpful as well for stability.

im sure the 2 fans at the top of the case are extracting the air as there is a vent just at the back of the case a put my hand in to see if if it was blowing the air into the case but doesnt seem that it is so must be exhausting the heat, when i play games my temps are usually fine they never rise above 55C also removed the panel for the optical drive and have a desk fan blowing cold air into the case while gaming so not sure if it will help to cool down the VRM, also dont think i use a XMP profile i will check though, and check compatibility with the RAM

UPDATE : i checked the ram is compatible according to this link

i did check it before i bought it but just wanted to double check as take that off the list, its really bugging me tbh, as with the XMP i dont really know what im looking for, if you could point me in the right direction

For the VRMs, Looking at your motherboard (from pictures), do you see the the line of capacitors (tiny short cylinder shaped) and blocks on the opposite side of the cpu from where the memory plugs in? This is between the cpu socket and the rear motherboard ports. As the primary VRM area, it may be helpful to put a small fan directly on the area. Ironically, depending on cpu cooler type, this area may get decreased airflow. This is a balancing act as you don't want airflow from your cpu cooler impeded

Just want to reiterate, loose cables in the airflow paths can cause turbulence and decreased airflow. bundling them, your path you route them through, and carefully zip tying them out of the way is helpful for smooth airflow.

You didn't mention your case. Not sure of what fans it has, but options to increase CFM (cubic feet per minute) flow may help if your current fans aren't as efficient.

To check if you are running in XMP mode for memory, you'll need to go into the BIOS. Your motherboard manual will have that information.

Running a memtest program may be revealing. One can be found at:

A memory failure may indicate a faulty module. It can also indicate faulty power delivery to the module.

Stress testing your system for stability isolated from the graphics system may be helpful. If you fail stability at stock clock rates on your cpu (not overclocked), it could be faulty CPU (unlikely), a CPU or VRM cooling issue, or faulty power delivery. There are many programs that can help you monitor cpu temps during the test to make sure they are within normal ranges.

How and how long to use the programs to test I will leave for you to google. Detailing each would def take this post into TLDR territory.
