It is possible to get a new PSU DOA not normal but possible. Barring that I would think motherboard. Possibly cracked or warped especially around the main connector. The new psu didn't cause the fans to move at all? How old is the board? Can you see any areas that appear burnt or any swelling of capacitors on the motherboard?

yes my new psu dosent cause anything to move and doesnt make any noise as far as the motherboard its fairly new supports ddr2 ram and i took it out and i dont see any fried components or cracking but iguess it is possibl it is m y mobo. would my old psu making a tss noise and causeing the fans to move a little mean its still ok and my new( really cheap 35$) psu be dead even tho its new?

Being that cheap it is very possible it is dead. $35 for 600watts woah. Before buying anything else I would have the old PSU checked either by a technician or by puting in another system if you do not have a meter yourself to check it with.

Could be an issue with the power switch itself as well. Do the fans move or jump each an devery time you try it with the old psu? Does the new one have all the same connections that the old one did?

yes they do but not right away i have to wait like 5 to 10 seconds before it will jump again but has done it everytime my old psu actaully does work and ther is nothing wrong with it put into another computer and it booted right up as far as the switch goes i could test that and see what happens. and yes both psu have some connectors and both psu do work in other computers how can i tell if its my motherboard or if it could possibly be my cpu?

At this point I am betting motherboard depending on how the switch checks out. The only way I konow of to test would be to put cpu in another system. You may want to call a technician and see if they can test it for you. Last cpu I fried the hdd still spun and all the fans and lights still worked so I am leaning to motherboard.

On the new psu is there a little slide switch may be red or black right below where the cord plugs in? If there is make sure it is set to 110 or 115 which ever just not 230.

Is the four pin connector from the psu connected to the motherboard?

old one psu yes its connected and yes its at 115 im just having this thought that its mycpu which came with my old motherboard and my rams brand new and unfortunaly i have no way of testing those on a diffrent computer unless i took it in to a techy... but i am debating if i should just sell my parts and buy a new computer thats better or just fix this problem.

my computer seems to be trying to get the post it seems like it keeps restarting the proccess. i dont know i just have had about enough of trying to fix this thing lloll

How did you test the old psu? Have you tried the new psu with the new motherboard?

Try reseating your ram again and maybe test with one stick of ram at a time.
