Computer automatically powers off

[siaokia]

Hi peeps,

I'm currently using a Pentium Celeron 2Ghz, Kobian (Mercury) P4M266A MoBo,1 x 256mb Kingston DDR 333 and 1 x 256mb Kingston DDR 266 Ram, 40GB Seagate HDD, 16x LG DVD Rom Drive with a 400W PSU

Recently my comp has been going heywire... sometimes the computer will just suddenly shut down by itself as if the power had been pulled and when i try to restart the comp, the computer will also just power off even before reaching the video card screen... and when finally it does boot... it will shut down again...

All these started happening after I installed the DVD drive... but I've tried disconnecting the drive but the problem is still there...

peeps anyone know what's the prob? Thanks

Possibly could be heat issues, or a bad power supply. Also, check your PS connections, as you may have loosened one up when you did the drive install.

That's where I'd start.

Hi there,

Thanks for the advice... could it be a MoBo prob? how do I check if it's a bad power supply?

Thanks again

unplung the power cable of the dvd drive and test, maybe your power supply is not proving enough juice.

I'm having a similar problem, you might find some answers here.

Washe> yup I've tried that already... still it doesn't work... so far my comp's been ok for the past 2 hours... just afraid that it will power off anytime again...

Gil> thanks for the link =] maybe it's really a PSU prob... guess I better get one to test if the problem still exists... what wattage would you recommend? I'm using a 400W PSU now...

Thanks peeps

no, 400W is fine imo, just try a different one.
