Sometimes it start, sometimes it dosen't

Few days ago I went on took out my GPU to see if there's enough space for my next GPU upgrade, then put it back in place. However, that night when i tried to start it, the can hear the DVD drive and CPU fan, case fan spun for half a second and then stopped, it won't start while it kept doing it automatically. I thought it was problems caused my dusts, I cleaned everything with a air blower and a vacuum cleaner without touching the mobo, and it started eventually, but the problem came back today. Having no idea of what happened, i checked on all of my cables to see if they are loosed , and it still won't start. Then I decided to send it for repair, still, I gave it a last try, after accidentally banged it on the floor, it started normally, except for a bit of stuggle( DVD drive made weird sound)

Now I'm guessing that it is the power button causing the problem

Please help ! THX

What operating system are you running?

Did the computer boot the OS then stop or did it stop before the boot had finished?

Win7, and it stopped before the OS boot

This doesn't seem to be a power button issue.

Has anything changed in the system since it last worked apart from the removing and reinserting of your GPU?

A bump and it starts working again - suggests a loose component - as you have checked the connections (worth doing again) - remove and refit graphics card and memory sticks to make sure fully home in their slots - check the connections to the hard drives and DVd drives as well.
