the story: was turning on the new build and fan is working, hear the sound of the computer running, but the LCD display doesn't show the boot up screen. try it a few more times with different video cards and no video card. still, the same problem. and then like 20 seconds after its turned off (for the nth time), the power supply (we think) blew up, there was this loud pop and this light coming from the inside of the case. We switch it to a different power supply and it boots up, but same problem. Hopefully all the other parts are okay! (please lord, my c2d..) My brother built it and he's build 2 computers before so you would think he knows what he's doing (but thats beside the point here). Thats why we think its power supply problem and not a problem with the other main parts. So asking the experts here to identify if its because there isn't enough current/power from the PSU thats causing the LCD display to not work? (i assure you the LCD is 100% functional). For me, i would think the power outlet supplies all the energy it needs for the lcd to work and its a graphics card problem. or could it be some other reason??? Core to Duo e6300 Asrock 775Dual-VSTA 512mb pc3200 and 512mb pc2700 ( we did try just the pc3200 to see if it was the source of the problem. but its not) Asus x1300 pro video card 120gb maxtor ide hard drive aopen 16X dvd-rw tsuname leo-46 case (psu is a goner now) so now im planning to buy a good PSU if its the source of the problem (antec or enermax) but i need to know how many watts I need +30% on top (for future upgrades).
