Sorry about the long description just want to give details..my sons old computer(A dell XPS 410 was my old computer that I gave to him that I upgraded) that he got from his moms house(sitting in basement) started up but no video..OK. I took it home with me ..I thought..he needs new card. I put my GTX 250 in that I know works cause I just took it out of my computer from an upgrade and I get the same thing...no video not even a BIOS screen. everything powers up fans and all but nothing on DVI or VGA inputs..after awhile I thought that maybe it could be the HDD??? I can unhook the SATA and power and the puter still powers on with no beeps and I can plug it back in while running and still nothing..I did notice that the front might have had water or moisture on the front bezel and not sure if it touched the hdd..Would a bad hdd not give you any video or not start up or anything not even any beeps or is it the motherboard..??? I am perplexed...shoot me any questions...
