Connected everything together, but when turned it on for the first time, it started up, then died down again (keeps doing that every time I turn off PSU from the back), then started up and stayed on, but no signal to the monitor. All fans working (Case, Graphics card, and CPU)

What I tried doing:

Made sure, the 24 pin and 8pin are connected (even tried 4 pin)
Taken Ram out (no beep, am I supposed to get it, like everyone says)
Tried 1 stick at a time (both)
Made sure graphics card is properly inserted int PCIe slot, made sure 2 PSU connecters (6pin each) are properly attached (although if the fans are working that shouldn't be the problem?)
Tried disconnecting all extra devices, but have to try that again, not sure if I got them all. Was getting tired by that time, so stopped experimenting.

One thing I think I've done wrong is when installing heatsink onto the mobo, first time it haven't fitted properly, so I lifted it up again (thermal paste included with Core 2 was spreaded), and put it back on. Then when the comp wasn't working I tried refitting it again. Is it essential that after applying thermal paste you don't keep lifting heatsink up from the motherboard? Whatever the case is, I'm going to buy some thermal paste and refit the CPU, then pull the mobo out of the case and try to turn it on with just PSU, ram and Graphics card.
Any suggestions or help would be appreciated.
 
You'll need to clean and reapply thermal paste whenever the contact is broken in my opinion. Grab some AS5 or similar, but be careful when applying it, it is conductive.

My advice in these situations is usually remove eveything that isn't essential, i.e. add-in cards, HDDs, most of the RAM, etc. Then try booting having reseated everything. Also triple-check the cabling and power is good etc.

Do you have another PSU you can test with, or do you have another system you can test that PSU with? It may well be your problem, although the corsairs are great, there are always duds unfortunately. You won't get a beep unless you have a speaker attached btw (i.e. front panel connector type).

Reset the BIOS using the CMOS jumper or taking out the battery for about 10 min.

The GFX could be at fault, does the 260 have a green/red light on when it's getting enough power? My 280 has a green light at the end when it's all good. Some of these cards also suffer from power connectors not tight enough, so check they're right in and making a good contact.

Once you've done that let us know, then we can narrow it down.
 
I had exactly this on my last build... Turned out to be a faulty memory stick. As you say, should get a few beeps with no memory installed. I wouldn't worry too much about playing about with the CPU / Thermal paste and try it again with just CPU, GPU and Memory. Also, swap the sticks around in the slots just to be sure.
 
Usually when the thermalpaste has been put down and spreaded it usually needs redoing as the force applied above has say spreaded the paste out a bit more and when its refitted that force ontop may not be as much as before so it wouldnt make propper contact however ive done this once or twice and it hasnt been a major problem but i would re-do it if i was you.

as a whole, ive had a problem like this once or twice but a quick unplug of everything and i was away but if you've tried that then idk what to sugges :S
 
Thank you for your suggestions, I'll try all of that when back from work, and I'll grap some thermal stuff and cleaning liquid on the way. I have a green light on my Mobo, if its on, does it mean its working, or could the light be on, but some other part of mobo be faulty? I tried with both my ram sticks as I mentioned, but I'll get a friend to grab his, so I will try it with different make/speed.

Havent seen any lights on the graphics card, will try to take it out, have a look, perhaps refitting it could solve it...

Can PSU still be faulty even if it powers up all the fans? and perhaps mobo (judging by the green light on it)

Is it possible to get BIOS withour RAM?

Green light on the mobo means it's getting some power, could still have a problem. Trying some other RAM is a good idea, yes.

GFX may have one, mine is at the back (blanking plate end).

The PSU could still be faulty, even if it powers up the fans. They do not require much power, and the load incurred when turning the CPU, GFX, etc all on could be enough to overload it with a fault.

Don't think it is possible to get to the BIOS without RAM, usually you get nothing and beeps from a speaker, or a screen sying no ram or words to that effect.

Read the Antec manual to find if it has a speaker, usually they're attached to the bottom of the case. My P182 doesnt have one, I see little point in them nowadays anyway.
 
Mobo manual will show the right pins for speaker and front ports etc.

Blanking plate end, I mean the end near the outside of the case, sorry.

In fact I do, will be trouble finding the right wire though :S, and anyone know where to connect it to on the mobo. Also if I do that how do I decifer the beeps?

Do you mean the end that shows up from the back of the computer, where all the usb, lan ports are... If so I only have 2 DVI and 1 S-Video (I think its S-video) and nothing else
 
Yeah, the back of the PC. I've only seen the light on the inside, but I never go behind my PC, so it may be on the back, but it's definitely visible inside when it's on. Again, i'm not sure if it's a feature of the 260 series.
 
Page 2-35 of your Asus manual will show you where speaker connects... Can also download from Asus site if you don't have one.
 
K, I've taken everything out and only powered up mobo with CPU, graphics card, with 1 stick of RAM, still nothing.

I checked the PSU on my other computer and it works, however because my other computer is so ancient and its an AMD, there is no chance to test CPU, ram, or graphics card, also it has an AGP graphics card, which I can't test on my new mobo. Will try and find a friend who has a newer comp.

So until then I'm kind of stuck what to do here.

Also attached the sound from my old case, and there are no beeps at all
 
Sounds to me that the motherboard is not getting the required power (most would beep when they get to BIOS or at errors).
Other things to check would be that the CMOS jumper is on and in the right place. (check the manual to find where it its) check the BIOS battery is definately there as well (never seen it not be). Also is your GFX card's 6pin connection coming from different rails - if you have a 2 molex to 1 6pin connection. The 2 molex should be on a different rail.

Contact OCuk about possibility of RMA for your motherboard would be my suggestion.

How can the mobo not get enough power, if its just graphics card and the mobo, the supply is 520W. Yes I checked the CMOS jumper, removed it to clear a couple of times (put it back on after), also removed the battery now, was advised to do that by the technicial from OCuk.
What you said about connection is very hard to understand for me, but what I have is, PCIe x6, to the graphics card, and I have 2 separate wires. They also have an additional x2 on one end of each, but that can't be used (from what I've read its for some graphics card that have 8 pin connecters)

Got a mate to bring his functional graphics card and ram, to test the mobo. If that doesn't work and the fact that CPU is rarely faulty, I'll be sending mobo back for testing.
 
K, sorted it out, I know you prob not as excited as I am, but its working and I'm really happy. But just for educational purposes, it was solved by simply taking the battery(cell, whatever u call it) out of the mobo for about an hour or so, and then putting it back in.
Now it comes up with:
"Reboot and select proper boot device... etc" which is more normal.

Anyways thanks for your efforts and all the best ;)
