Sudden Power Off · DIGIT-ARC

N

Hi..
I am facing an unusual problem for the last three months.
My pc powers off all of a sudden, no overheating problem, i changed my heatsink paste. But of no results, when i took it for repair, there it was running smoothly, but after returning back home this same problems occurs. I have recently changed my motherboard. My config is: P IV 3 ghz HT, intel 945 gcnl mobo, 1 gb ddr2 ram, 256 mb graphics card, 250 gb SATA hdd.

Thanks in advance.

1. Check SMPS, use a friend's SMPS for a few days.
2. Check your house's power cables... Check the socket the comp is connected to.

1) PSU problem. Use someone else's as suggested above.
2) RAM problem. Run a MemTest.

^^ I havent heard of RAM problems causing power downs, they usually cause restarts. I might be wrong, though

Get a UPS(has inbuilt Voltage regulator+Surge Protection+Backup)...i think ur power supply voltage is fluctuating or having higher/lower voltage than the range or 190v to 270v A.C...better get ur supply checked by an electrician.......

if u have a knowledge of using Digi. multimeter.......try checking the supply voltage-should show around 210-270V A.C(if ur are skilled at it else don't try..be careful doing that-dont touch any terminals by mistake)

do you have a UPS?
if yes get it checked.....or try connecting your system directly to the power socket.

Dude Ur SMPS Is on its last leg change it....man
If Possible Check UR SMPS Power Connections as well as internal wiring inside the cabinet
a lose connection may be a problem!!!!!!!!!!!!

or the system may not boot (by not giving a beep sound

)
