No monitor signal with 5870

So, about 3 weeks ago I got a PowerColor HD5870. Installed it, hooked up the 2x6 pin PCI-e, fired her up. No monitor signal. Turned it off, took it out, put it back, no monitor signal. Tried both DVI ports, nothing. Put old card back in, everything works.

So I figured it's DOA. Sent it back to Newegg. Yesterday I got refunded and overnighted an XFX HD5870. Installed it, blah blah, no monitor signal. Kay, wtf? Either I'm lucky enough to get two DOA in a row, or something isn't right here.

What the fuck.

Also, once I put my old card back in and start up, it says that my overclocking has failed. I'm not sure what that's all about as my overclock has been stable for like a year. It did this on my first 5870 too, so I figured maybe my overclock was screwing me and reset CMOS...but that didn't help any.

Suggestions please. I'm getting very irritated.

Specs: AMD x2 4800+
MSI K9A Platinum
G.Skill 2x2GB DDR2 1000
PC Power & Cooling Silencer 610

Well, turns out it was just the fact that the card didn't want to work with my hardware I guess.

Cause I got a new CPU (Q9400) and mobo (Gigabyte EP45) and now it works.

did you remove your previous gpu drivers. could driver's installed for an older card cause problems when a newer card is installed? I don't actually know. just guessing.

It's rare that some motherboards aren't compatible with certain GPU's.

One of these cases is an EVGA 8600GT and a P5Q Pro; no signal.

Nah, cause it had no signal at all. If it were drivers, it would only mess up when Windows loaded.

That motherboard had this molex plug above the PCI-e slot. I never really knew what it was for but I heard somewhere that it was for PCI-e power. I might be shooting in the dark here but perhaps this is what was screwing it up - I dunno. All I know is that it works now and I am very happy.

On a side note, what the hell can I use to monitor temperatures and adjust fan speed on that 5870? Nothing seems to support it.

Is that the only way?

I hate CCC.

5870 isn't supported.

There is no overclocking or fan control.

I forgot about GPU-z, I'll try that.

EDIT: Ah, GPU-z gives me temp monitoring. 40*C at idle, with 21% fan speed. Noice.
