Hi
My problem is that the system turns off all of a sudden. When I press the On button it doesnot start. I have to turn off the UPS and turn it on again. Then if I press the on button it starts.
What could be the problem?

Before this prob, was ur pc workin fine????
Ur PSU definitely needs a change...
Can u enter the bios?
If yes, enter bios and check the procy temp.....
I have this prob since I bought the PC. As the problem occurred occasionally - once in a week or so i didn't care for it. Now also it occurs like that only. Previously I thought that it was due to power problem at our place.
Process Thermal Margin: 37 C
Motherboard temperature 43 C
MCH temperature 45 C
ICH temperature 82 C
PSU may be the culprit....
now try removing the GPU and connect the monitor to mobo and switch on....
Try to reconnect everything once. Else most probable PSU.
Hi, I also came to the conclusion that the PSU is the culprit.
I have replaced the 300 W Prime Source SMPS with I-ball Sprinter -500 W. Hope My system will work fine.
whats the cost of the new PSU? theres better option available but maybe you went for shopkeepers words. all the best. just hope this last for a couple of years.
Thanks guys!
The I-Ball sprinter 500 W costs Rs. 2400/-
After the replacement the problem solved.
