Hello

i upgraded my pc : gb p35-ds3l ,e8200, ati 3850, 2x1gb 800mhz 5-5-5-15 RAM with 2 x2 slots of RAM.

when i assembled back and tried to boot the pc started and shut down after 2 sec.
i pressed again power on and it seemed to boot normally but i got no signal. i thought i was misfitting of vga tried to fit it again( i had some probs on fitting in the past) but after many tries nothing happened . every time the mobo worked and fans and leds everything. Also i cleaed cmos.
so i disassembled hdds ,next vga , even all ram and cpu and when pressed power the mobo started without any sound. i suspect i may caused prob while adjusting the vga.any ideas is my mobo fried or cpu or vga prob? how i can tell ? can i find if i can enter post without vga?
thx alot

If you are using on-board VGA then try putting in a graphics card and see if you get a signal; if neither work then its probably a bad mobo. Try another mobo if needed; luckily LGA 775 boards are common.
