I have purchased a hp ethernet 1gb 2-port 33t network adaptor. I wanted to install it into a HP Elite desk 800 Gl Tower(320 W PSU) I installed it but then the PC would not boot up. It gives 5 beeps which is the code for memory error.

I took out the card put it in a different HP computer which booted up fine.

The PC has no graphics cards, 1 HDD, mouse, keyboard, 1 extra dual serial port card. In the bios the slots are all active, and it is in legacy mode.

Anyone got an ideas what is wrong?`

  • Check the RAM? If 5 beeps is a memory error, I would look at that. – Tim G. Jul 29 '16 at 14:35
  • It's incredibly unlikely to have been an issue with modern power supplies and hardware, but did you happen to ground yourself when installing the card protecting from ESD? – JaredT Jul 29 '16 at 15:07
  • Does it boot when you remove the network adapter? I'm with @jatuttle0, it's easy to inadvertently damage hardware if not properly grounded. – root Jul 29 '16 at 19:35
  • Assuming the other computer you tested the PCI card in accepts the same RAM, try testing each stick by itself in the other computer. Do a bunch of single-change tests and see what fails vs what boots. – JaredT Jul 29 '16 at 20:13
  • I removed the card and it boots fine. I also put the card in to a different pc where it booted fine. Idid ground my self :). I get a new card tomorrow so i will try that and report. – DavyGravy Jul 31 '16 at 7:32
