PC will not turn on

Hi guys i am having a serious problem. When I press the power button the cpu fan starts to spin and then stops and the computer does not turn on. Can anybody help me PleaZZZZZZZZZZZZZZZ!!!!!!!!! It would be greatly appreciated.:cry

 

can you give us a lil more info, like what lead up to it???was it acting weird befor this happend??and u can tell us what u have for a set up ram,hd,cpu,ext.
this would be helpfull on our end to better give a diagnoses for your issue.thanks.:major

 

Thanks for responding. Yes it was acting weird... there were times when i had to manually spin the pc fan or leave it for a half a day b4 it would power up again.
Specifics
I have an AMD processor, 160G hd,a 512MB DDR333 MARKVISION RAM,windows xp system,a K8M800 MOTHERBOARD. hOPE I COVERED everything.

 

ok i hate to ask but can you tell me what the symptoms were be for it just stopped???any error codes??

 

ok, no problem... a couple of times i got some dumping memory screen. Away from that i only had a problem after i shut it down it wouldn't power up again right after, if i needed to. I woud have leave it off for sometime or manually spin the fan on the motherboard. her
otherwise there were no error codes that i can recall.

 

ok i see.. well i have a dell with the same problem,and on the back of the tower their is a set of lights labeld A B C D and on that mine wont start either and like u said if i leave it alone for an hr or so it might start up normaly and it might not but i noticed that the lights (A,and B) would be lit up in yellow and not green and dell told me that is a memmory indication,so mi have a faulty memmory stick, i havent run any test yet but you may want to remove 1 stic ata time and see if that helps. or wait pull both and power up and see if you get the mother board to beep.if it does than power off and stick 1 stick back it and see if it will boot.if not power down agen and pull the 1 mem stick and stick the other one in and power on agen and see if it boots.if it dose than you know that one of your memmry sticks is bad. if none of this works than let me know. and we will try something else. keep me posted.:major

 

thnks... just tried it it didn't work, the fan just spins then stops

 

ok if you tried the memmory thing and that didnt do any thing than i have to agree with plodr about the power suply.:major

 

thanks earl & plodr ill try and do that soon hopefully tmrw. will let u guys know how it goes. Thanks agin

 

you are welcom just keep us updated.:major
