my specs: Mobo : asus p4p800-uay chipset : p4 2.6 HT SC: Audigy VGA : Geforce 5700. so here is the problem, the pc itself started but there is no picture from monitor, right to say that the monitor led is blink... its like it getting nothing from the vga. for your info: VGA is fine, Chipset is fine, Monitor is fine, PSU is fine. i tested this to another pc.. i had re-assembled the pc again, nothing change. could it be agp slot broke? is this so? can agp slot be change? i try with another vga, the samething happens, nothing from monitor.
