You had one 0x50 error and these can be caused by defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card).
The problem is your minidump only cited a general Windows core driver.
You had one 0x8E error and these are almost always caused by hardware issues, but sometimes can be caused by a faulty driver. But, again, nothing specific was cited by your minidump.
The other three were all 0xC2 which means a kernel-mode process or driver incorrectly attempted to perform memory operations. Typically, a faulty driver or buggy software causes this.
2 of the dumps cited general core Windows drivers, but one cited TM_CFW.sys which is a driver belonging to TrendMicro's firewall.
I suggest doing the following:
1. Go to Dell's website and update for your particular laptop.
2. Temporarily disable your firewall and see if it brings stability; or update your firewall..
