Help plz. will not load / blue screen error message

I had a P4 1.6 emachines system break down on me.

Everyone I talked to suggested to get a new mobo due to the symptoms (crashing, locking up, finnaly freezing at windows load screen).

I just bought a new mobo off newegg (ecs, PM800-M2) got it installed and now as it starts to load windows it goes blue screen error saying:

a problem has been detected and windows has been shut down to prevent damage to your computer.
at the end it gives this technical information:

*** stop: 0x0000007b (0xf7c46640, 0xc0000034, 0x00000000, 0x00000000)

I am totally lost and dont know how to fix it, and was told it would cost $400 just to find out whats wrong. I tried new bios settings and reinstalled windows (again, 4th time...) and still same error message.

I have in the system right now:
x2 elpida 512mb pc2700
256mb geforce fx 5200 video card
herules fottissimo 2 sound card
factory 60gb hd

the old mobo was a ECS L4S5MG.

If you need more info please let me know, any help / tips would be greatly appreciated.

p.s
My friend is bringing over a new HD tomarow to see if thats the problem, i will post the findings.

We ended up having to totally reformat my Hd and now it seems to be working. We didnt want to have to do that but nothing else worked.
