Generic PC help thread.

I'll make this short.

PC: Has computer parts.
Issue: Boot up is lagged, black screen after mobo screen, integrated nic fails.
Issue2: Figured it was ram, bought new ram, install ram, left "damaged" ram in, boot, it boots with about 2 seconds of black screen instead of 5 mins.
Issue3: Remove Ram "Damaged" doesn't boot at all, no-post beeps, nothing, dead. HDD spins, all the lights say "ON" but video card not sending any signal to the Monitor - Tried two diffrent monitors. No post beeps.
Issue4: Put "Damaged" ram back in, boots up as per-normal.
Issue5: WTF?

damaged ram will cause failed memory tests, not missing hardware.  it's not your ram.

is there a yellow question mark in your device manager?  if so, get your motherboard cd and (re)install the nic drivers from there.

the following can cause missing integrated hardware:
 - hardware disabled in BIOS (option such as "Enable Internal NIC" or something like that)
 - "Plug and Play OS" setting in BIOS set wrong (also try "Clear ESCD Configuration Data")
 - fucked up motherboard
