You have a fist full of dumps. I looked at six dumps.
All of your dumps point to hardware. They blame atikmdag.sys and Direct X most frequently.
To begin your troubleshooting, uninstall McAfee using this removal tool: Info > Tool. McAfee is known to cause crashes on some Win 7 systems. Down load and install MSE http://www.microsoft.com/security_essentials/ in its place and make sure Windows Firewall is turned on.
Stop error code 50, PAGE_FAULT_IN_NONPAGED_AREA - usual causes are Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus, Device driver, NTFS corruption, BIOS.
Stop error code 3B, SYSTEM_SERVICE_EXCEPTION - usual causes are System service, Device driver, graphics driver, ?memory.
Stop error code 124, WHEA_UNCORRECTABLE_ERROR - usual causes are Hardware, Incompatibility, May be driver corruption.
Normally when I encounter error code 124, I stop right there and list the things to try. However since I see only one error code 124 and all of the 50's, I will approach the other error codes first. In the usual causes for error code 50, you will see Anivirus listed. This is why I suggest you get rid of McAfee ASAP.

PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced. This cannot be protected by try-except,
it must be protected by a Probe. Typically the address is just plain bad or it
is pointing at freed memory.
Arguments:
Arg1: fffff88008f01c48, memory referenced.
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.
Arg3: fffff88004a5f235, If non-zero, the instruction address which referenced the bad memory
address.
Arg4: 0000000000000002, (reserved)

Older third party drivers can create problems with Win 7. I find two on your system that are slightly out of date. Update these drivers.
LGPBTDD.sys Wed Jul 01 14:47:52 2009 - LGPBTDD Driver is a driver file from Logitech Inc. belonging to Logitech GamePanel Software.
Downloads. This driver was indicated in two dumps I looked at.
Rt64win7.sys Thu Feb 26 04:04:13 2009 - Realtek 8101E/8168/8169 NDIS 6.20 64-bit Driver for Realtek 8101E/8168/8169 PCI/PCIe Adapters.

If, after updating your drivers and uninstalling McAfee, you are still getting BSOD's, read the following on the 124 error. Upload any new dumps and we will begin checking hardware.
