HP Pavilion a4316f-b 6GB RAM 1 TB HDD Desktop Tower Computer Not Working (READ!).

Item exactly as pictured. 1 TB HDD and 6GB (3 x 2GB) RAM included. Hard drive has been wiped/formatted. System powers on and seems as if it should work but nothing comes up on display when monitor was plugged in to test. Could be a simple fix, not sure. Will obviously need everything re-installed since I’ve formatted the HDD. AMD athlon II 620 quad core processor. NVIDIA integrated graphics. DVD burner. Power cord included. No physical damage whatsoever. Fast shipping.
