Monitor screen shuts down, cpu fan ramps up to 100%

[Wingback18]

Hi everyone

I have a a88xm plus motherboard with a A10 7890K
32 GB of ddr3 ram @ 1866 Mhz 9-9-9-27
Rx 480 with a custom cooler
750 watt power supply

This week , the PC was working fine , after I uninstalled avast antivirus . With the windows 10 antivirus it's fine .Then PC started doing this , The monitor screen goes black , it says no source , the cpu fan spikes up to 100%. I have to hold the power button to shut it off wait a few second to turn it on again That's the only change I've made to it .
The cpu it's OC to 4.5 Ghz , it's stable as it gets . The RAM too . That the only change I remember making before this started happening .

Should I install back avast ??

The latest drivers for the 480 are installed .

I also ran a disk to check for errors and nothing

After a few tries I got it to finish the virus scan and nothing .


It's not dust. I keep the pc clean, it has 3 120 mm fans

The power supply looks to be working fine too .

If anyone can point me in the right direction on what to do , it'll be my h appreciate it .

What make/model PSU do you have? Temps? Looks like your GPU is losing signal causing the odd crash. Any logs in event viewer? RX 480 OC'd? If so, I'd set to stock again.

hi
its a termaltake 750 though power gold .
the gpu looks fine ....
no events in event viewer , i checked !!!!! lol

i did that too , back to stock , still crashes ..

but something I've been looking into , i recently installed another two ram sticks , they are different frequency . but in the bios , i set it to be the same . i took them out . that put the pc to work again

I see. Still odd to cause that specific problem. You did same thing I would have regarding settings, at least to try. Are they mismatching kits, or totally different?

 

[Wingback18]

yay..... i did something right ..lol

they are different frequency and different kits . i even change the timings in the bios too and i up the voltage

now , everytime i put the case together , i put the cpu in the place it goes . it doesnt work ..lol

Something loose somewhere, such as a cable? Maybe moving around the finished system causes a cable to pop out.

thats my next project , im going to sleeve and cut the cable length , its going to be fun . i have everything ready

but i think im going to change this ram , but it doesnt make sense . I've to do so . this pc i built its about 4 years old , i think its time for an upgrade . and ryzen its looking pretty good

Something wasn't loose , it was the mobo , in her last posts .
I try it turning on the PC with no ram. I get the same as if there was ram .
I took the cmos battery out , waited 10 mins. That didn't work
I try the on board vga. , didn't work either , the only thing left , it's try another pci lane .

Thanks for your help

Glad you got things narrowed down a bit. A Ryzen build would serve you well from the reviews I've seen.
