Hey everyone, This is my first post on the forums, so I don't know if this is a bad question or not. I have a custom built computer that has never worked. When I first got it it would never POST or boot at all. It sounds like it is working, but nothing comes up on the screen. I have tried almost everything. I returned the motherboard three times and it tested OK everytime. I also replaced the power supply with a 650 watt Ultra Power Supply. Still nothing. Here are the specs: AMD 3000+ Dual Core CPU Asus A8N-SLI Motherboard 1 GB Corsair RAM EVGA 7300 Video Card SeaGate 120 GB SATA HDD If you need anymore specifics, let me know. I will be glad to look them up again. I have booted it up a few times by luck, but it managed to lock up within 10 minutes of it turning on. I can also boot it up when I reset the CMOS. Then it will boot up. Any suggestions will be greatly appreciated. Thanks.
