I have an HP envy h-8 1534, Specs are here:

 http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?spf_p.tpst=kbDocDisplay&spf_p.prp_kbDocDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c03639067-7%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken

I push the power button, power light comes on, fans turn on, monitor stays in standy mode. If I plug the monitor in after I turn it on the monitor comes on for a second (with a blank screen) then says no input signal. I've tried multiple monitors / cables. All monitors / cables work with other computers. The computer does not have integrated graphics. I've bought a new graphics card (EVGA GTX 750ti), because I was sure that was the problem, it has the same problem.

The computer was working fine one morning, tried to use it later that day and had this problem.
Any help would be much appreciated.

What happens if you try to start in Safe Mode?

No sounds, other than the various fans.
As for the PSU, I don't know what brand it is (or If it even has one), but I do know it's a 460W.

So the monitor is working,the videocard is new and working,the cable is upright but there is no screen.There is no power or CPU is the problem.

Try to clean your CMOS battery which is attached with your motherboard; this is just like a watch battery and after you clean it out by rubbing it a little bit put it back in. Then clean your RAM by pulling it out and also dust off your CPU.

I did a quick search for information about the front panel LED display but couldn't find anything.  But I suspect that this desktop is like others and has a LED display which indicate hdd activity.  Are you seeing any sign of hdd activity?  If this computer is successfully going through the POST there should be sounds indicating activity with the printer or scanner.  See if you can open the optical drive.

Well, I removed/cleaned the CMOS battery, reseated the video card and ram, and now it works perfectly. I'm guessing one of these got knocked loose.
Thanks for the help guys, I was  on the verge of just buying a new desktop alltogether.
