Hi Guys This is my build i been using it for 4 years Recently i face a problem that my display turn off and GPU fans start running at maximum speed suddenly I think and make noise while the computer keep working and don't turn off (if a video was playing it keep playing) then i had to turn it off from psu if i try to turn it on again it stop on VGA Ez Debug Led.

What i try to solve this problem
Check ram (swap them change slots)
Check GPU cable (change it to new one)
Use new GPU cable
Update BIOS from MSI center (it failed when the computer restart) then try to update it via M-Flash it went well (even the display turn off while flashing bios)
Format computer (display went off in update step on format)
Sometimes the computer works just fine for one day or so then suddenly the display turn off and the GPU fans start working at max

For troubleshooting, try to rule things out. First i would try to rule out the PSU in such cases, this can only be done by using a different one. It has to be known good, not too old, and of decent quality. Maybe you can borrow one and connect it on-the-fly using its own cables. But also, if you can borrow a different GPU, that would be another important thing to test.

Thanks for your answer i test my gpu in a friend setup it gave D6 code error which mean GPU not detected now i got no display and once i got the boot blink display then it goes off not sure if the problem is from PSU or GPU or Mobo now
 
With this happening in your friend's PC, there is a high probability of the GPU having some kind of defect. Try to borrow your friend's GPU and test that in your PC. If it boots up fine, then you need to get a new GPU.

cannot borrow my friend GPu cause i will need a PSu in my friend pc as i told you the GPU did not work , and it shows D6 code in his motherboard that mean gpu not detected.

i test it in another friend pc that got MSI motherboard it show. VGA Led too but we try to use other DP that not used before the display work till windows login then it go. off and when we restart the pc same problem it stops in VGA ez Led.
 
Yeah, i'd say, get a new graphics card then. Something like an RX 6600 would be 50% faster as well, an RTX 4060 another 20% faster over the 6600.
 
You can, as long as it's at least the 400W version of the Pure Power 11. Those cards have a higher efficiency than your old card, so they have a similar power draw for higher performance.
 
Yeah, that's easily enough then.
Thank you well i will see when i can buy GPU also i notice that the computer don't boot up correctly the keyboard TAB button don't function like to show a sign that its activate so you know the system boot up correctly however i made many CMOS reset and bios updates I think that the reason and it need to be reconfigured
 
We already have clear signs that the GPU has a problem. So now you need to use a GPU that works properly, then your problems should go away, in theory. If you still have some problems, we troubleshoot more. But three PCs where the GPU doesn't work properly, i think it's proof enough that it developed a problem.

Right thanks i will keep you updated in this post.
 
Ok. By the way, just looking at your specs again, are you really using a single 8 GB RAM module? Or is that a mistake and you're using a kit of two modules? Because a single module means single-channel, which is cutting the RAM bandwidth in half. Single-channel DDR4-3200 is like dual-channel DDR4-1600, too slow. You always want to use a kit of two identical modules, in the 2nd and 4th slot from the left (slot A2 and B2) to run dual-channel, only this way you get the proper RAM performance. And of course, a lot of games require more than 8 GB RAM nowadays, for gaming you should always have 16 GB. So if you buy a new GPU, i would also order a new RAM kit of 2x 8 GB DDR4-3600.

But when i research your RAM model name, it comes out as a "Patriot Viper Steel DIMM Kit 16GB, DDR4-4400, CL19-19-19-39". So maybe you have two modules installed, and they're running at DDR4-3200 for some reason, maybe the CPU's memory controller can't do more? The sweet spot would be DDR4-3600, above that it becomes too difficult to run properly (without having to use a divider and lose performance again, see point 4 of my RAM thread).

i have 2 x8 in total 16 yes and 3200 slots got problems i think cause only way it work. now is A1 B2 if i try to put them A2 and B2 i think they wont. work and i will end up with DRAM Ez debug led Thanks for the information and thread i will read it
 
Ok. If you use them in mismatching slots (like A1+B2), that's no good either. So you need to get it working in A2+B2. When you have the new GPU and flashed the newest BIOS, try again to get it working properly.

i think now i have the newest bios even i think im on beta like you see in picture it stuck now on DRAM and if i recall i use to use them in the schema you mentioned
 
Can you even troubleshoot properly now, or are you only checking if the DRAM LED comes on instead of the VGA LED? Try each module individually (alone) in slot A2. Also, remember which module was in A2 and B2, and reverse the positions. These are things to try, if you can only look at the LEDs.

Only LED that i can test with one Ram only work in A1 and B1 solo.
the two at same time they work in A1 and B2 now.
