Just acqured a used Alienware Desktop Computer and it won't power up

[vortalexfan]

OK, the memory it uses according to the manual is DDR4 and I had some DDR4 memory chips laying around but possibly it might of been the wrong speed of DDR4 memory, because I know at one time (during the DIMM and SODIMM era anyways it used to matter what speed of memory you used on certain motherboard makes and models.)

Also maybe the wrong videocard?

I'm not familiar with high end gaming computers and how they spec out and or how they work compared to a normal non-gaming computer.

I would guess that gaming computers would use differently spec'd parts compared to a non-gaming computer and maybe that was my problem?

Normally, gamming computers have more big cabinets, robust PSU, better ventilation and a motherboard with a lot of slots, for using 2 videocards + soundcard etc, and accepts hi-end CPU, due to choosen chipset. Most are prepared to accept the lowest end RAM for compatibilities (is not needed to test with hi-spec RAM), but sometimes yes, incompatibilities can occur.
