Hello guys, I have a problem with my pc, using MSI PM8M3-V. It boots up but there is no display. The monitor says "Check signal Cable" tried it on my laptop cable and monitor are fine. I then did these:
1) CHecked video card - I replaced with an old one which definately works and still no activity. I then thought it could be the AGP slot but when I put the original card back i removed the power connections for it and it started beeping, so I presume the slot is ok? Not sure though.

2) Made sure all cables were in correctly - yes

3) Removed CMOS battery and replaced - no difference

4) Memory - removed one stick - no difference, removed other stick - no difference.

4) CHecked CPU - seemed to be seated in correctly but removed and replaced anyway, again no difference.

Please help. It was just working before, i turned it off now when powering, nothing works.
