Ok guys I really need someone to help me out here! Let me try to describe to you what is hapening...

One day I press the On-Button and my pc wont boot up.

- I can hear/see that all fans including GPU fan are working.
- On monitor I see "No signal"
-4870x2 has 3 red lights on it.

Now if my card would be dead, then why does it boot up like 1 out of god knows howmany times...

What I did:

- Changed the cables for the spare once
- made sure everything is connected
- updated BIOS
- put my card into another PCI slot
- removed mobo battery

When pc is on it can work for days but then when I turn it off and try to turn it back on it gets 3 red light on the graphics card and "no signal" on monitor.

Also when I just do a restart it boots up just fine.

It's working right now after i was trying for like 5 hours to turn it on.

I have looked around google for hours, people either have to weak power supply or they have 3 red lights right after plugging the card in for the first time.

maybe the heat sensor inside the card has broke or something?

Please HELP! :cry:

It could be caused by a faulty PSU,what's your PSU model ?

Yes, it's likely PSU issue.
What is your PSU? brand? model? how old?

I got "Be Quiet Dark Power Pro 850w" It's about 2 years old now. I did try differend sockets btw, same problem.

The pc is been running for 2 days now, I'm to afraid to turn it off thinking it wont start up again.
