I built my own computer last week. I used an AMD 3500+, VNF4 Ultra ZENITH VE mobo, and a cool case and a harddrive that i already had. Well the first problem i ran into was that my old computer used a different kind of memory so i couldnt swap memory with my old computer. Therefore, my new computer has no memory. second, there were no hookups on my mobo for my monitor so i had to use my old card. Third, the power supply uses a 20 pin connector and my mobo uses a 24 pin connector. I tried plugging it in anyway and it would just make a short ee that was kind of gravly(not real clear and clean). Well naturaly i thought that the powersupply was the problem, so i ordered an adapter for it. Well the adapter got here today and i used it and guess what?! It still wont boot. My power supply is 420 Watts by the way. If anyone has any ideas about what could be wrong, please dont hessitate to post them. ANY help will be much appreciated. For the mean time, my lifeless computer will continue to just sit on my desk and mock me for sinking close to 500 dollars into it(thats a lot for a 16 year old that only works weekends).
