Clean or replace the CPU fan, sounds like it's overheating.

i cleaned the fan, put more termal paste on the cpu and check the fan's rpm which is 2700 , but it still restarting

any more suggestions plz
tnx a lot

It could be the RAM, try replacing the RAM if cleaning the CPU fan doesn't work

oh sry tought different ppl will answer,

ok well i checked the ram, hear this
the MB has 3 slots and each have a 512mb ram, well i removed all of them and just put one of them, the computer started and then restarted, so then i tryed the 2nd one but this time the computer started and there was no signal on the screen, so i tryed the 3rd ram and the samething as the 2nd happend, tryed the other 2 slots with the 2nd and 3rd ram and still no signal on the screen,
then i tryed the 1st ram agian on each slot but then it showed me no signal on the screen.

do u think its the motherboard or ram??,
tnx a lot

looks like motherboard problems. first of all check the RAM slots on your motherboard, remove any dust hanging about. then check the gold connectors on the ram for any scratches or dust. if that doesnt work then try the ram in a different pc if possible. finally, take out your CMOS battery, clean it then put it back in. its a bright silver little disk. Be careful with it. if that doesnt work try another computers battery. im not sure if there are problems with changing the battery so research it just incase.
