Hello,

I have purchased 4x RX 580 cards one of them is RX 590 they are mining well individually each giving me 29+ Mh/s but when combined together they are working fine but whenever I run the miner it's crashes my computer and giving me the blue screen. I am super newbie to rig and mining so all help would be appreciated. I have just contacted a technical guy who have told me it's a settings issue and he also said this rig can not work on windows, I need Linux for that and charging me $250 for the setting on Linux. I never thought it could be that technical. I am pretty confused and spent all the money on the GFX.
I am also sharing screenshot please see to it and let me know if it helps!

Best Regards,

First, I hope you not trying to use your personal computer for mining at the same time. That's a bad idea for sure.
Check how much power your PSU has. it seems like you don’t have enough power when it’s all on. Buying some cards it's not enough, there is a lot of work and knowledge which you should have.

Why don't you try to install it yourself HiveOS or samplemining. You will find enough tutorials on how to setup your mining rig with them, also all settings you will do through the dashboard panel.

Listen to this advice and fix whatever you did wrong

1. Make sure you have more than 2gb RAM on motherboard for smooth operation
2. Increase your page file, calculate your 4x gpu memories, for example 8gb per RX580 in four places that's 32gb, so go into page file and add 32,000 MB and apply, may asked to restart PC
3. After things balanced out make sure you deactivate windows 10 updates, they are well know for reducing hashrate speed

The information you provided is too limited, what is the wattage of your power supply? How much watts are those rx580s drawing? Do you know that a single rx580 can draw up to 140 watts when mining? Unless you do some tweaking on core voltage to lower power draw, I think the culprit is your power supply, if you don't have 850 watt power supply you are doing things wrong

The technical guy isn't qualified or don't have experience about mining rigs, believe that, he said the setup won't run on windows and I'm running 8x RX580 8gb on windows 10 OS here with no issue at all, if your page file size if small the miner will crash, not every mining softwares warns people about page file size

Mining on windows can be tricky and needs practice, you new to it. even small windows update can ruin your rig. crash above you told is looks like driver crash.if you insist using windows then:
1-install fresh windows dont connect to ethernet. disable all updates and defender. make virtual memory big as 50-60g
2-install good driver from list which miner recommends.
3-dont oc your cards yet make sure they all appeared on device manager.
4-start mining and then optimizations good luck

I have 2000v power supply, power is not the issue, secondly this is mot my personal PC, i bought a new 4th gen motherboard and the ram is 8GB 4x2GB

4 memory slots can cause some problems. Try to eliminate one by one module.
Try with HiveOS. Install it on USB Flash (min 8GB). The installation itself shouldn't cause you any major problems if you follow all instructions. Then you can easy overclock cards on OS dashboard.
They have Android and iOS apps, you can monitor everything that you need.

Editing Page File resolved my issue and now I can mine :D
The second big issue I am getting is AMD Drivers, they keep crashing every 5-10 minutes causing blue screen again and again.
Please also help me with this!
Thank you all!

Here is what AMD says!

Mate not everyone can view Dropbox images because it requires an account it's better to use imgur or order image platforms that doesn't require an account, also try changing your AMD driver to the latest version you can use ddu uninstaller to erase the old driver and install the new one

AMD RX 580 and 590 can work side-by-side with no issue make sure you install the latest AMD driver and also make sure that both cards have normal temperature because if one is not well cooled the temp can be the reason why it's crashing

Thank you all so much for your help, because of you guys I withdraw $200 :D
Few thing I want to add:
1. Make sure you never touch your rig, hit the table while cleaning or by accidents while running.
2. Make sure your cables are not overheating.
3. No sparks in the power extension or any plug.
4. Avoid any power failure or power outage problems.
5. Make sure your cards are not overheating if yes then change the paste on the main chip by removing heat sink also get an AC if the environment is too hot.
This will definitely help everyone!

Those are the common factors I have found practically which causing crashes such as the blue screens or  multiple restarts.

Good Luck and Happy Hunting!!!!
