I think (well almost sure) that my psu has screwed my comp

Boy it has been a long and arguous journey to build my new computer.... First i was sent a defective gigabyte nforce 4 mb with no northbidge fan that was overheating... sent that back and got a new msi nforce4 ultra... had to send some ram back cause one was not working... got some new ram... then one day i came home from school.. my gf said that the computer had turned off and turned back on once and then would not even post....arghhhhhhh...
i reset the cmos and took out the battery...then tried just motherboard and cpu.. led said that the proccessor was not working or installed incorrectly... so checked it out... looked fine so i put it back in.... oops bent one of the pins on my amd64 3500+ socket 939 ..... arghhhh... had to buy a new one..... got it yesterday installed it yesterday no cheese.... so i did the same things that all the troubleshooting guides say to do cmos reset different combinations of components.... still no swiss... i am either going to run out of money are i am going to have to start taking some strong drugs before i lose my mind... i frequent these message boards as well as others and have read that cheap power supplies are ussually the hidden culprit in many cases... well i think i found the lil f'er, I am a newb to building so when i chose my components i paid no mind to the psu... i just used the one that came with my cheap case... a rosewill case with a 400 watt psu.. nice case but i think a ratehr lackluster psu.. does anyone think that this psu is the insidious pest to which i can attribute my problems????now b4 the flaming ensues just remember that i am a newbie....

I think it definitely could pose a problem. yes

I would recommend swapping another PSU into the system (see if you can borrow one).. a GOOD one of course, and see if that helps.

or the motherboard could be bad....

Yeah i tried it with a more reliable psu from my friend an aspire piano black 400 watt... but still nothing... only the fans spin...and still says proccessor not working.... i think what happened was that the psu blew the 4 pin 12 volt connection on my motherboard.... does this sound right??

 

[PurdueRy]

whatever it is, its probably something wrong with the mobo. Sorry dude

 

[automaton20]

thanks....rleemhui , yeah i figured that...now i have to buy a new motherboard... i really liked the new msi platinum nforce 4 ultra it was so sweet... even the posting screen looked cool.. it is nice to have a community of other computer enthusiasts that can feel your pain... Does anyone else think that it is possible for a cheap psu to short the 4 pin 12 volt connection on a motherboard

 

[PurdueRy]

probably not short....but it could just received a spike in voltage or current and sent that right to your mobo. Get a surge protector with power filtering to avoid small surges

 

[automaton20]

yeah i have a everything for my computer hooked into a surge protector... hmmmm

 

[PurdueRy]

it may not have filtering. Its usually a really high end thing.
