about 2 months ago i was playing a little wow and my computer turned off. i thought the plug was loose but it wasnt. for years ive been running a 300 watt psu with upgrades like radeon x1950 pro card. now i know thats bad but it ran fine for 3 years.. i opened up my comp each year and found the 12 v rail and the box where it connected to was burnt. some capcitators were poped up. i went to the tech and they told me to replace the psu first. ok i replaced the psu with a 450 watt one. keep in mind the 300 one was still working as i tested it with the 12 v rail unhooked. tested the 450 one like that the same. but when i plugged in thr 12 v rail its the same problem when ud press power on ud hear a split second "pts" sound and the fans spun 1/4th of a sec. ok i replace the motherboard too got a good one which is compatible with everything. same story tho with the 12 v rail in the pts sound and no power... so i am thinking now is it the cpu? cpu is a p4 3.0 ht 90nm processor with a stock heatsink. i took it out it looked fine. even with the new mobo its the same story.. anyone? i tested ram and vid card and hd they worked.. is it the cpu guys? i cant power on my pc...
