pc problems

[carlangas]

Hi all,

 

this morning i tried to boot up my pc, only to find that nothing apeared on screen and the num lock light was flashing. the pc was on and but nothing happened, no hard drive noise. it boots when it wants to and sometimes it even shuts down itself as it tries to boot, once it boots it seems to behave ok, i tried running a diagnostic tool from its manufacturer (compaq) and when it got to the hard drive tests it just reboot itself, I run diskscan and it gave no error messages. now its behaving ok but im afraid it will keep on doing this. have any of you had a similar problem? or know of a free diagnostics too out there.

 

thanks

yeah im running xp home sp2, the pc never gave me problems. its 3yrs old but it gets the job done. p4 2.5mhz 1g ram

sounds like overheating to me but since it works if it boots off ... must be a ram ..... do u hear any beep sounds ?

Also could be hard drive controller - considering it crashes on the hdd diagnostic.

thanks for the responses, there is no beeping what so ever. I will look into the hard drive driver. ive had those for a year now and had not had any problems od any kind.

is just dust in some chips or conector, tke the memory and hard drive off and clean up the dust and then reboot, also take out the videocard and clean the fan, use compresed air to remove the excess of dust from the processors.

Ever, I cleaned all components, disconnected the harddrive connectors, ram, cards. and havnt had any problems, ive rebooted a few times now and it seems the problem is gone, maybe something was loose..
