First, it is highly doubtful you PC is dead. However, did you mean to write IRQ? The reason I ask is because there is absolutely nothing on the internet concerning this designation.
However, Stop 0x44 Multiple_IRP_Complete_Requests is. If this is what you meant to write from what I have researched it appears to be due to third party drivers.
The thing is we don't know what software/driver it could be. If you attach your minidump files (and if it is permitted here) Zip together the five most recent by using the option found in the Manage Attachments button, and I'll attmpt to read them for you.
