Need help with inspiron 3650 upgrades

I purchased a dell pc that had some added parts but kept the same i3-6500 and one stick of 8gb ram. Recently i bought an extra stick of 8gb ram and a i5-7500, however now the pc would light up whenever pressing the small button on the back but the pc wont turn on. i was wondering whether this is a power issue or a user issue and whether i'd have to get a new motherboard or get a lesser cpu

Your Inspiron 3650 can support 6th generation processors only.  You added an i5-7500, which is 7th gen CPU.  Hence the PC won't boot.

Two separate issues.

First, that CPU is not supported -- the system will not power up with it.  Return the original CPU to the system.

Then second,

Try the added RAM.  If it doesn't work, contact your memory supplier for compatibility information.

chino is spot on.  top cpu for 3650 is i7-6700.

ejn is on correct topic too.  3650 (like 5040 Opti) takes DDR3L memory for desktop only (low voltage DDR3).  Not regular DDR3.  certainly not DDR4. 

regular DDR3 memory would physically fit but is not supported.

similarly, i5-7500 would physically fit the cpu socket but is not supported by 3650 bios.  Dell did not write a bios update to support 7th on the 100 series chipset of 3650.  a bios update is required but Dell often does not help user in that regard.  that is the long answer

DDR3L memory was used during a transition from 4th to 6th Intel gen when Dell had some bridge ram spec.
