HP Slimline 290-p0043w Desktop PC Product Specifications

you probably have a problem with the memory module
in its original configuration it is mentioned 4 gb
I can't know if it's one or two modules
so if only one, it will probably have to be replaced and
if you have two, you have to test one and then the other

Take the recommended precautions, to open a computer
after unplugging the plug, keep pushing the power button for a while
if only one module
remove the module, then replace it correctly, possibly in another slot
reconnect everything, and restart!
no better, you have to buy an identical module, or why not install more
