Hi, as shown in the title, I've been getting a mostly random BSOD that says PCI.sys didn't do it's job. I'll post the minidump files below.
📎 AI Summary:
The thread discusses recurring BSOD errors related to pci.sys on a Windows system. The initial poster reports random crashes, and subsequent contributors identify potential causes such as memory corruption, outdated BIOS firmware, or recent hardware changes. Recommendations include updating the BIOS, disabling memory caching/shadowing, and testing RAM with Memtest86, with an overall focus on troubleshooting hardware and driver issues to resolve the BSODs.

Solution
Looks like the dumps are pointing to memory corruption. You can try some of the following
- Check your hard drive and make sure it's not full (page file issue)
- Check the manufacturer site for any BIOS update
- Look in BIOS if you have either memory caching or shadowing, try disabling them

Probably caused by : pci.sys ( pci!PciProgramMsiXInterrupt+95 )
Followup: MachineOwnerthis is quite a common bugcheck and is usually caused by a recently installed application. Have you installed anything new recently?
Driver wise you look in good shape, did you install these drivers from your actual support page?

Your Bios however is out of date.
BiosVendor = TOSHIBA
BiosVersion = 1.20
BiosReleaseDate = 05/02/2014
SystemManufacturer = TOSHIBA
SystemProductName = Satellite C55-B
Latest bios is running to 1.70 and has many fixes. If your unsure on how to flash the bios then leave it to a proffessional.
If the bsod continues then you'll need to test your RAM. Windows does have a memory testing app but it can miss errors and the best app for the job is Memtest86.
If you open the link below you'll see you can run Memtest86 in two ways. You can either burn it to disk or install it onto a USB drive it's entirely up to you. You'll then need to enter the bios to change the boot order so you can boot from either the Disk or USB stick you have Memtest86 on.
You must test for at least 12 hours unless it becomes obvious there is a problem straight away.
