I bought a new graphic card for my PC, before I had a 8400GS and now I've bought a VTX ATI 5450 card, however, after installing it, my computer stopped booting and made a clicking sound through the internal speaker.

I tried this card on a different PC and it is working fine.

If I remove the card the PC works again.

I've double checked cables. I've taken the PC to bare bones with the graphic card and the same problem still occurs. Also swapped out the PSU with a GS700 and the problem was still there (The GS700 is a certified power supply unit by AMD).

My Specs are the following:

  • Abit SG-95 motherboard.
  • Pentium D 3.2.
  • 2.5GB RAM.
  • 230V 400W PSU.
  • ATI 5450 Graphic card that I'm trying to install.

Any help is appreciated.

Could it be that the power of the PSU is insufficient to power the new video card? Could you verify with the PSU rating of the "different PC" – Karthik T Jan 8 '13 at 13:53
He needs 400 watts, 1 gig of ram and an x16 lane, all of which he appears to have. – Snesticle Jan 8 '13 at 13:58

400 watt PSU minimum is required. There is a possibility its power related and also the PCIe slot could be defective. Check your BIOS to ensure the slot is enabled as primary video. – CharlieRB Jan 8 '13 at 14:03
@user1860175 - Which means what Dave noticed is likely the reason its not working. The computer that isn't working will be unable to support the graphic card you purchased. Your power supply not supplying enough power could be a problem. What other hardware do you have connected to the power supply? – Ramhound Jan 8 '13 at 15:29

The card you have bought is PCI-E 2.1

Your motherboard has PCI-E 1 slots.

Now, some cards can work on PCI-E 1, some at reduced performance and others fine, but not all. I suspect yours cannot due to the AMD site not declaring it is compatible.

Please note, there are posts on the forums that some have fried their motherboard by attempting what you are, so do proceed very carefully. To be honest, my suggestion in the comments of trying a more powerful PSU may have been ill-advised as it could have caused damage.

According to the standard, all PCI-e v2.x cards should work in a PCI-e v1 slot. And all PCI-e slots should be able to supply up to 75 Watt power via the PCI-e slot (The card has no extra power connectors and feeds of PCI-e supplied power). So it should just work. -- @user1860175 Does the card work in another system? – Hennes Jan 8 '13 at 15:34
@Hennes , I agree, but we both know should means nothing :)! Yes, his card words on another machine. This is a post with similar question which may be interesting reading – Dave Jan 8 '13 at 15:38
Aye. Hence my use of italic. (Which you picked up on, but which is hereby made explicit). – Hennes Jan 8 '13 at 15:45
Yeah I'll have a read through that, and perhaps try contacting ATI support as well as Abit, I'll get back if they give a reply. – user1860175 Jan 8 '13 at 18:08
