Boot up, turns off, boots up

All,

I have a Computer, 3.0 Ghz Pentium 631, Asus P5MT-M, the prolblem I am having is that sometimes on boot up what will happen is bios boots fine windows boots up just barley and then the machine tries and boots up again.  I open it up move the parts around and it works again... not sure what is going wrong??? Any suggestions??

THANKS!

I think your power supply may need to be replaced.  This is a common symptom, where a cold boot doesn't work initially, but a warm boot right after will work.

Hi,

I would suggest you remove all the parts and re-seat them after ensuring all contacts are clean.

Next, I would reset the CMOS via the CMOS jumper to flush any wierd settings out of the computers setup.  I.e. sometimes if the Setup is wierd i.e. if someone had it beofre you and did something like jack the Front Side Bus Clock speed to 280 Mhz or something like that you would have stability problems.  You never know.

So, reseat everything and reset CMOS.

Also, connect your speaker, so you can hear any beeps when it doesn't boot.  It sounds like a motherboard issue to me.

As Callandor has indicated the Power Supply is a likely candidate but another source could be a the motherboard.  As you have the case open look around for any obvious blemishes or bulging capacitors on the motherboard.

Hope this Helps!!!

All,

Thanks for your input,

some specific questions to Callandor & David523, I am using 380W for 4 SATA's and One IDE, is this enough power? Should I move up?

The rating is high enough, but the unit may not be working properly in order to supply enough current.  If it isn't a quality manufacturer (PC Power & Cooling, Enermax, Zalman, OCZ, Antec Trupower, Thermaltake Purepower), go for a higher-rated supply.

Hi, althoguh high enough, it wouldn't hurt to upgrade your power supply.  It would at least rule that out.  Still, I think it is a motherboard issue.  I just see a lot more motherboard than powersupply issues.
