BSOD at random times, error 0x0000001E and 0x0000001A

[duncanpano]

Hi everyone, recently our desktop computer has started to crash and get the dreaded BSOD. Initially it appeared to be a problem with a driver for one of our phones, which I removed but the problem has resurfaced. Seems to be getting more regular and taking the computer longer to reboot and login now. Attached is the crash dump file as per the posting instructions, along with 2 pictures of the BSODs themselves. Any help on how to fix this would be much appreciated.
