I cant figure this out, my computer starts up but my monitor wont come on. I have had this problem now 3 times in 2 years. I've replaced motherboard, memory, power supplies, and changed video cards. I currently have a k-7 fsb 400 motherboard with amd sempron processor, 350 watt power supply, geforce 5200 ddr 64mb graphics card, kingston 512 ddr memory, wd cavier 7200rpm hard drive, and a dell monitor. everything starts on computer but monitor wont. yet monitor does on my friends computers. i've reseated the memory twice, tried differant hard drive, tried differant video card and power supply. still nothing. It must be the motherboard right? I just bought motherboard 4 months ago.
