We need way more info than that.

First specs, brand and model, as much as you can tell us, including video card.

We need brand and specs, on both power supplies.

A little history.
How old is this?
Do you clean it regularly?
How long has this been happening, on the old power supply.
What was the room temp when it shutdown.

Exactly what jumper?
The CMOS reset?
Just removing it should do nothing, you have to put it on the reset pins, for it to do anything.

There is no reason to reset, on a power supply change.

The CMOS jumper has 3 pins, 1 and 2 are normal, and 2 and 3 are reset.

My pc__
AMD Phenom II X4 965BE
MSI GTX560 1GB DDR5
MSI GMS E35 Motherboard
8GB Trancend ram
XFX PRO 550W core edition psu (now)

Delta Electronics multi-rail psu (+12v rail 30A) is the previous one

the thing is i used the Delta psu for 4 months with that rig and faced no problem. Then I just get the XFX PRO 550W for single rail replacing delta psu.

After changing that I am facing this problem. it is hapenping after playing above 30 minutes. Except gaming pc is running perfectly.

MSI Kombustor and prime 95 shows the pc's temp is ok.
If the psu is problem, how to check it's error.

**It was COMS jumper and i think it isn't the problem. :P

It is pretty hard to test a power supply without test equipment.

If 2 power supplies do the same thing, I would not suspect the power supply.

A 450watt should surfice, unless it is crap.

I'm not sure of Deltas, or XFX, but would trust XFX more than Delta.

If you have a multi meter, you can test the Rails under load.
Without recording equipment, you will have to have someone watch the meter, while you game.

The voltages, should remain fairly steady.


My first guess is still heat.
Either the video card, or the CPU.
What are both temps, just before the crash.


I am not familiar with you indicator lights, but a flashing power button, usually means standby, or sleep mode, not shutdown.

What operating System?

Test your RAM.

How about viruses and malware?
Not my first thought, but all bases must be covered.

Rereading.

Did the Delta work?????
