The pc is a brand new unit. Its full system specification is as follows:

Intel Core 2 Duo E7500 3.0GHz
Samsung 1TB 32 MB 7200RPM
Seasonic SS-500ET Active PFC

Samsung DVD-RW SH-S223F x22
Gainward 9500GT 512MB GDDR2
Compucase 6A19 Black NO PSU
When I brought my new pc home, and tried to operate it, I saw all the light and heard the noice of a working unit, but the screen stayed black. I brought it to the lab of the store where I've ordered it. The technician switched all abovemention items (excluding the MB and the monitor, which was left at home), and found no fault in any of the items. Therefore, he put all original items back. Surprisingly, the system started working normally.
I brought the pc back home and connected to my SyncMaster 940bw monitor. The unit started, no signs of any BIOS related steps showed up. Still, when windows xp (SP3) phase was reached, it continued in a normal fashion.
I brought the computer once again back to the lab. The technician checked it throughly (I was out of lab while testing took place, but the system was under testing for 5 hours. (I asked the technician which checkup programs were used and he mentioned the following, which may or may not be the exact list used: Furemark 1.65, OCCT 2.0, Orthos, CPUz 1.53.
If I missed any needed information, please let me know and I'll try to provide it.
You seem to concur with my suspicion that the problem stems from an incompatibility between my video card and my monitor. The response I got for this idea was rejection.
I don't have a card to try this idea, but strangely enough, I connected my pc to another samsung monitor, a syncmaster 173v and it work falwlessly.
