Help with what motherboard and cpu to buy/help with pc problem

[dirtyolive]

hey everyone,

I'm not really sure where I should post this so I'm sorry if I post this in the wrong place.

I'm trying to find what motherboard and cpu that I should buy. I don't have a preference for either AMD or Intel motherboards so i would be fine with getting anyone of them.

Currently I have an asus m3a32 mvp deluxe motherboard with an amd athlon x2 7750z cpu and the reason why I want to change them is because whenever the computer gets put under load the screen goes black(it goes other colors too like orange with horizontal lines, blue with horizontal lines etc). I have changed the graphic card and gotten a new power supply but the issue is still there. I have also tested the RAM and the harddrive and all of that tested fine without errors(also tested RAM one stick at a time). I RMA'd my motherboard and got it back but the problem still persists.

At this point I have no idea what else to do except get a new motherboard and cpu -_-

Here's what my computer currently has:
ASUS 790FX M3A32-MVP DELUXE
AMD ATHLON X2 2.70GHZ 7750Z
4x1GB DDR2 PC2-6400 U-DIMM 800MHZ
1xSEAGATE 250GB SATA 7200RPM 16MB HDD
1x ATI RADEON HD 6870 1GB
CORSAIR 750AX PSU
1x DVD DRIVE

For budget I think the most I can spend is like $400ish.

Any help would be appreciated. Thank you.

This would make for some solid system guts around $400'ish
I've never had a prob with ASUS
And 5'oclock is up the street from me (8miles). Used them for many years.

Edit: You having tried another GPU (vid card). Your video issue sounds like it might actually be a monitor problem not a system issue.
