My computer keeps on rebooting

A file or application (I don’t really know what it is) keeps on getting access to my startup and causes my computer to reboot. I tried to delete it but it recreates itself every time after being deleted. I took a look at my startup and here what I saw:
KernelFaultCheck
dumprep 0 -k
Location: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
Path: %systemroot%\system32\dumprep 0 -k

Please help me prevent that file or application from getting access to my startup.
