Installing a PCI USB 3.0 Port card & PC Fails to boot.

PJ5ingh · Jan 24, 2015

I have tried inserting PCI card without sata power connector which is optional anyways. My PC would try to boot up and then cut off after 2 seconds. Then it would retry it 2 seconds later and cut off again. My concern is that would it fry my motherboard if it keeps trying it again? because I just ordered another one because I though it was defective.

This is the card - http://www.startech.com/Cards-Adapters/USB-3.0/Cards/4-Port-PCI-SuperSpeed-USB-3-Adapter-Card-with-SATA-SP4-Power~PCIUSB3S4

FYI: I inserted this in a regular PCI slot. I never installed the Drivers that came with it before installing the Hardware. Do I need to do that first? I don't think that it would matter.

On the Technical Specifications tab:

System and Cable Requirements: Available PCI slot, Available SATA or Floppy power connector

Why not provide power to it as it could resolve the issue? If it still doesn't work, then it's defective or it isn't compatible with your motherboard.

Installing drivers won't help until the OS is loaded; your system doesn't even POST.

I tried the power floppy connector with 4 pin molex on my power supply and it didn't work. I tried it without and it still didn't work. So with or without it doesn't work. I looked at the card carefully when I received it and it looks like the card have few pins on the bottom that are mashed in. They are not poking out. I made a clear conclusion that the card is defective. I have already ordered a replacement of the card. My question now is lets say if the new one doesn't work and my pc tries to boot up again. Is it over killing my motherboard or something when it does that? Do i need to be careful or be worried?

Pictures. Look on the very right side. There are two clear spots.

Thank you for the reply in advance.

the problem may be on the card if new one works then the problem was in the card

Still waiting on a concern about trying it again & not frying my motherboard on an accident. I love my PC and I just don't want anything to happen to it. Will it harm my PC if it tries to reboot over and over again like it did in the past?
