Alert! Error initializing PCI Express Slot 4

Question

Greetings Everyone: When I booted up yesterday, I was stopped on the way by this message: 'Alert! Error initializing PCI Express Slot 4'. I was/am able to boot into Windows (Windows 10 Professional) now by hitting the F1 key, but the error persists every time I restart or reboot. I read about a similar situation (on another thread here at Dell Forums .. ) that the problem was a couple of burned-out capacitors on the PCIe SAS Controller Card, so I'm wondering 1. if this is also my problem and that, therefore, the fix for the problem is still a valid one (Alert ! Error initializing PCI express slot 4 - Dell Community) and then 2. where to get the replacement parts (either the two capacitors, or a new SAS card instead, if that will work) as my computer was made by Dell in 2010. My last question concerns the card itself, why do I need it/why do I need an SAS Controller Card? (I have a single, 1TB SSD and therefore, have no use for RAID, that I know of anyway). Can I safely remove the Card altogether, or does it have other necessary functions (other than RAID) that would make that impossible? Thank you for your help Kindest Regards,David

I had an old PC that had an add-in RAID controller card. when there were no RAID drives detected on startup (I had only one hdd), it gave an initialization error. once I took out the RAID controller card, no more error on boot.

Re: Can I safely remove the SAS controller card altogether

yes. you do not need it.

Optiplex 980 slots:

PCI (white SLOT 2 & 3, 5V 64bit & 32bit)

PCI Express x16 connector (blue SLOT1)

PCI Express x16 (wired as x4) connector (black Slot 4)

it has only two PCIe slots in addition to two PCI slots. 980 980

I thought that I should add that my SAS Controller Card is in my PCI Express Slot 2, while my Slot 4 (the PCI Express slot that the error message is pointing to) appears to be empty. Thanks again!!
