I'm 1000% positive that it's not my monitor's problem.
maybe you put it back together wrong. here's a tip- next time you decide to do something like that, make sure you know what you're doing!
did you probably didn't ground yourself and when you touched the motherboard you ruined the on-board video card..
I have to agree you shouldnt touch this if you dont know what your doing, check everything again, and make sure all cables are in correctly including your ide, or sata cabling. Take out the ram stick and put back as this is usually why nothing shows. Take a look at link for more help and info
Mkay, Check all power cables including all motherboard cables, which means the making sure that the power switch cable is in the right pins. If there is no beeps or sounds being emitted when you turn the computer on, you can almost right away assume it is a power issue, make sure the right cables are plugged in is crucial. Make sure everything is seated correctly: i.e. your processor, processor fan, RAM, CMOS Battery, Video Card, Network card (if you have one), etc. Make sure that the power supply itself is turned on, sometimes theres a black switch on the PSU and that could be it. Another idea is (and one problem i had) is to make sure there is no screws that are caught between the motherboard and the case (when you've seated the motherboard in the case) because that can ground the motherboard and it won't work, but i doubt thats the problem. Anyway, for the most part I would say this is a cable problem because the computer should at least turn on regardless of a hard drive or a ROM drive put in. Best of Luck! Any more questions?
