Upgrade causing problems

[staticx57]

Hey there I upgraded my ram/mobo/cpu today and kept everything else the same but now something isn't right.

The new stuff is:
Gigabyte ud2h-b3 Motherboard
Core i5-2500k
Corsair Vengence 4x4GB

Else:
PC Power and Cooling 750 watt (pre OCZ)
SLI 465 GTX
2xHDD
1xDVD ROM

The first sign is noticeably degraded sound quality when using audio over HDMI and anything even graphics intensive such as the windows experience index(meaning not at all) will cause a whine in the power supply that I have never heard before. I have been using this PSU with these graphics cards with no problems for at least the pasy year around but now with this upgrade i'm running into this problem.

Tell me I am missing something obvious as I do not want to spend money on a new powersupply.

Do you have another psu to try.this sounds like psu failure.

Unfortunately I do not at the moment.

Bumping this because I RMAd my power supply and I'm still having a boatload of problems. I get constant BSODs for no reproducible reason. It does not matter whether I'm running something stressful such as 3Dmark or prime95 and neither produces a crash related to the GPU drivers(surprise for nvidia) or anything CPU related (that I can tell). The BSODs are half the time driver related and the other half kernal related with a few that suggest RAM or HDD problems.

That being said I've run memtest86+ for 18ish hours with 7 1/2 total passes with all 4 ram sticks with Zero errors. I have also run check disk but on that same boot up when I went to login I got a BSOD before getting to the desktop.

I would probably start by pulling everything out and restarting by adding one component at a time. Maybe start with just 2 RAM sticks and use the onboard GPU at first, work your way up.

Yeah, sounds like RAM. Use 1 to 2 sticks at a time to narrow down which one.

I don't think the ram sticks themselves are bad. Hell they all pass memtest86+ just fine. I, however, have no experience with the z68 boards and google searches yield many ram incompatibilities with these boards and it seems im no different than any of these people that have these problems. I tried bumping my voltage to 1.575 still BSOD?
