Windows 7 Kernel-Power 41 (63)

I do realise there are posts already on this forum and many other forums, I have followed all the 'solutions' people have posted, I have not came across a person who said it has solved their problem, nor has any solved mine.

I am having the Critical error Kernel-Power 41 (63).

Every time I try to launch a game. I've noticed that people have this issue doing other tasks, some have it with transfering files, on itunes and simply just downloading music or surfing the net.

I assumed it was my power supply, I first ordered a OCZ GameXStream 850watt sli ready that was out of the box dead on arrival haha, so I returned it and took my 3 year old OCZ GameXSteam 750 watt sli ready my computer had no errors or warnings or critical errors at all for the first few days of running. these errors started on the 21st as you can see. For no reason what so ever. So I replaced my power supply with the OCZ Z Series 80+ Gold certified 1000Watt SLI Ready. My computer is still having the same error.

I've came across people saying to do things such as:

Updating Realtek driver (I'm not sure what that has to do with anything, it's just a sound driver although; I could be wrong.)

Updating the firmware on the HDD (I have the newest version)

Clearing CMOS (I've done that)

Checking the voltages running to the RAM and CPU and making sure they're default at the least (CPU is fine haven't checked ram so far)

Graphics card drivers out of date (I have the newest versions of the ATI Catalyst.)

Updating the Motherboard bios (I haven't checked that yet)..

These critical errors have just started 2 days ago, the tasks I was doing that causes them now, I was able to do perfectly fine before(playing video games such as left 4 dead 2, borderlands, audiosurf so far the only ones that have crashed my computer not so much as a crash but it freezes completely.) The thing that baffles me is that it just randomly started for no reason after the things I was doing were working perfectly fine before >.<

I have a brand new computer built last week, I'm not sure why this is happening!!

I'm running these specs:

Windows 7 Home Premium 64Bit.
ASUS P7P55D-Deluxe Motherboard.
Intel i5 750 Processor.
OCZ Reaper 4GB DDR3 Dual Channel ram.
OCZ Z Series 80+ Gold Certified 1000Watt SLI Ready PSU.
XFX Radeon HD 5770 (crossfire XFX Radeon HD 5770).
1 Seagate Barracuda 500GB 7200.12RPM 16MB(Super Speed enabled. ASUS P7P55D option in Drive Expert)
1 Western Digital 250GB 16MB 7200RPM (Ultra space, it's a ASUS P7P55D-Deluxe option when Drive Expert is enabled)
Logitech G15 keyboard.
Logitech MX518 mouse.
Logitech Z5500 speakers.
Samsung 22" LCD 2MS 10000:1 monitor.
Turtlebeach Ear Force-AK-R8

I'm pretty sure I have all the proper drivers installed I went to the websites and downloaded the windows 7-64 drivers.

If you need more information just let me know, such as voltages, or any other bios settings.(I have them all set to auto, default)

Thank you, all help will be greatly appreciated.
Brent.
