After I installed the Plugable USB 3.0 PCI-E express card I noticed my 64 bit Windows Vista system slowed down significantly. I thought it was the driver but after I uninstalled the driver the system was still slow. I then physically removed the card and restored my system to before the install and this solved the problem. Any ideas on how to fix this issue?
Thanks for posting, I’ll be happy to assist. The most likely reason why the card could slow down your system is if it is not installed in an X1 slot. The card is only designed to work in a PCI-e X1 slot and can cause many different symptom if it’s installed in an incorrect slot.
The next thing I would check is that it is seated correctly. To be sure you can remove the face plate or bracket and seat the card, then try again.
Also, can you say what the make and model of your computer is and what you had connected (if anything) to the PCI-e card while the system was showing the issue.
Let me know these details and we’ll figure out what’s next.
My PC is an HP Pavilion a6500f. I did not have anything connected to it and it was still slowing down the PC.
It looks like that HP Pavillion a6500f has:
1 PCI Express x16 slot for graphics card
2 PCI Express x1 slots
1 PCI slot
A USB 3.0 add-in card would only be sure to work in the two PCI Express 1x slots (the shortest black ones). Was that were the card was plugged in – and did you happen to have a chance to try the other one of the two?
What you’re seeing sounds like a low-level hardware issue with PCI bus or interrupts, that sometimes is solvable. And if not, we don’t want customers stuck with hardware that isn’t working for them – just visit http://amazon.com/returns and we’ll be able to get you a full refund quickly.
