Hello ,,

My Dell Precision T3500 doesn't run at all,,

When i runs it , The CPU fan and GPU fan Unusually become very loud

And nothing happens on the screen

And i've got this error code (3-4) on the front of my case
in the user manual this represents a Memory failure
but i've Checked all components
RAM-PowerSupply - GPU - CPU
It's all worknig on my other Dell Precision Computer

I need help :( !!!!!!!!!
