Witam,

I have a problem.
About 4 weeks ago i have changed my pc cpu,mb and memory.
it was working well until last week.
PC started tu turn down itself about week ago. There are two sympthoms:

1. Monitor is going black and it shows: "No Signal Going to Sleep", later PC is rebooting.
2. PC is rebooting, after this it starts again or reboot again while starting windows(xp sp3).

I dont know where is the problem. This is happening while surfing in net or playing games.
There was no overclocking.

My config:

cpu: Amd Phenom II x4 925 (am3)
motherboard: Foxconn A74ML-K (am3, chipset AMD 740G)
memory: 4gb ddr3 Kingston (w jednej kości)
graphic card: Gigabyte Radeon 4850 HD 512 MB ddr3
power supply: Chieftec GPS-400AA-101A - 400W - 12V1-14A(168W), 12V2-15A(180W), 5V(26A)+3,3V(28A) - 5V+3,3V-140W

Do You have any ideas what can couse this problem?

Thank You for help.
Best regards.

Yes you are maxing out your PSU.

based on a PSU calculator your system is requiring 415W

What spec should have a good psu?
Corsair VS 550, or OCZ CoreXStream 500 will be good?
I would like to change gpu some day for something modern (650TI boost or similar).
