startup problems

Just installed a Biostar M6VLQ with Celeron 1.3, and when you start it up the system runs for about 5-10 seconds and then powers off. Any ideas what could be causing this?

 

Sounds like a heat issue. Did you apply thermal grease to the cpu and are all the fans running ?

 

Yes I have applied thermal compound and the fans are working, that is the frustrating part.

 

Are all drives detected i the bios ?

 

It does not stay on long enough to get into the bios.

 

Remove the cmos battery for a couple minutes then reinsert it and attempt the bios view.

 

Could be that CPU fan RPM's are not correctly passed to the mobo (mobo build in security if CPU fan fails it will power off)

Try different CPU fan or more easy exchange the CPU fan connector with 1 of your case fan's if its got the same 3 lead connector !!! for diagnoses only !!!
Ps. if the CPU fan only got 2 leads you'll probably need a different fan , 1 which registers RPM's with 3 leads.

If still don't work , minimize your system hardware by disconnecting everything not needed except power supply , mobo , CPU , 1 memory module , VGA card & screen.
By reconnecting hardware 1 at the time you can sometimes isolate the culprit.
