Please double click on the critical error messages. In the lower right corner of the windows that opens will be a button labelled "Copy". Use that to copy (and then paste) the error reports to your next post.
FWIW - recent information about these errors that I've seen in other posts, tends to suggest difficulties with the Video card (if it's a PCIe device) and the allocation of IRQ's in the OS.
Here's 2 links about this (although they apply to Vista, I'd suspect similar results in Win7):
The system may stop responding during restart when a computer that is running Windows Server 2008 or Windows Vista Service Pack 1 has a PCI Express interface
A "0x00000124" Stop error message occurs when you use the "hot plugging" feature to add or to remove a PCI Express device on a Windows Server 2008-based computer or on a Windows Vista-based computer
