Windows Crashing / Multiple problems.

[Jeffenator]

Greetings ladies and gents,

I've got a couple of questions regarding the 'failure' of this pc.

Basicly it comes down to this:
Pc specs are:
Mobo: ECS H67H2-M deluxe versie
Proc: I7 2700k stock
PSU: thermal take 700w true power
Ram: 16gb Gskill ripjaw

Video cards tested on the system:
hd5870, hd3470 en hd6850

After putting in a MSI 7870 OC into the system, it keeps on crashing every 5-ish minutes.
With the other videocards the system runs perfectly. (re-installed windows aswell)

Aswell as a second problem:
I've bought a couple of HDD's (brand new formatted)
Seagate Bara's 400gb.
After installing them: my pc doesnt want to boot and the only 'issue' I get is that it asks for a HDD-password

Any ideas?

Thanks in advance!

The issue is either the power supply or the 7870. Try changing the power supply and see if that helps.
