Question about memory upgrade

Not sure if this is for the motherboard or the memory section. I recently upgraded to Windows 7 64 bit. I have 4 GB of RAM currently (2 X Kingston 2GB 240-Pin DDR2 SDRAM KVR800D2N5/2G). A friend gave me two Mushkin 2 GB sticks to throw in there (part 991850) to make it 8GB, but after installing the Mushkin modules my computer won't boot. I turn it on and the screen just stays blank; no beeping or anything. The Mushkin memory is not on the QVL from ASUS for this board. Is anyone out there using this motherboard/memory combo with success? I also noticed that the Kingston memory is 1.8V and the Mushkin is labeled 2.0-2.1V. Could this be the cause of my problems, and would it hurt the Kingston RAM to increase the DIMM socket voltage to 2.0V? I'm not interested in overclocking. Here's my specs:

Current setup:
ASUS P5Q
Intel E8400 3.0GHz
4GB RAM (2 x Kingston 2GB DDR2 KVR800D2N5/2G)

What I'm trying to add:
4 GB RAM (2 x Mushkin Enhanced 2GB XP2-6400 Part 991580)

The difference in voltage can be the reason. For reference, try booting with ONLY the Mushkin sticks and see if that works.
