oem desktop pc user here also. there are two components that are pretty much guaranteed to go awry with this type of hardware application. first things first, chances are your power supply that came with the unit is negligibly underpowered. i would recommend listening to POST beeps for an indication that the mobo can give you. POST beep indicator patterns can be googled. a nice power supply that i purchased for my sony vaio desktop is the thermaltake 430w. not bad for $40 and all the plug-in extensions you could dream of ...another thing to consider with a new PSU purchase is volts. all the watts in the world is useless without the voltage to jam those watts through the circuit.. seeing as your fan is blasting high speed on startup, that is going on during the POST (power -on self-test). another sure thing that will go wrong is your video card (i.e. gpu). if the gpu is faulty, your pc might be doing multiple looped boot processes with no display or disarrayed pattern display showing on your monitor. if you do decide to go the power supply solution route, make sure you document all connections your existing power supply is configured to before you dismount the existing PSU (power supply unit) and install your replacement PSU. also, check the back panel on your PC for an extra port for your monitor to plug into. that would be your provided "onboard" video. if your gpu is at fault, use this auxilliary port to connect your monitor AFTER you dismount your existing gpu from the mobo.
