Hello,

I have problem with my PC. it has a sudden shuts down. 2 days ago it shut down suddenly on idle after few hours of internet surfing. Yesterday I had no problems using my computer all day long and today it shut itself down again. This happened 4 times in 10 days always on iddle.
It only happens when it's on idle, temperatures are fine, around 35 degrees Celsius cpu and 30 mobo. I can play games for hours, run benchmarks etc. I don't know if it is a power supply Chieftec CFT-600-14CS 600W, which I bought used 10 days ago, before that I had LC Power 600w, which was shutting down on full load sometimes and thats why I replaced it. My question is could something else cause the sudden shut down excpet the PSU or it is 100% PSU's fault.

Also few days ago my onbard Realtek LAN adapter dissapeared, device manager does not see it at all...

My configuration: Gigabyte z77 hd4, Intel i7 3770 @3,4ghz, Sapphire 6950 Toxic, 3 WD HDDs, GeiL Enchance Corsa 2x 4Gb 1600 Mhz, Chieftec CFT-600-14CS 600W, Soundcard Asus Xonar DGX and Rajintek Wireless adapter. 4 system fans and fan controler.

PS. Ignore the GPU temp, it sometimes has a thermal sensor bugs...

I hope you can understand me, English is not my native language so sorry for grammar mistakes.

Thanks for answering. But main problem I bought used, yet Chieftec PSU, is a really low bugdet, I got it for about 40$ with 15 days warranty and I tought it's a good model for that money. The seller told me if this continues he will return me money and I will buy something better. But I would like to know is there anything else that can cause this occasional shutdown?

What I forgotot to mention is when shut down happens and I turn PC back on there is no "start windows normaly" or something like that. Just few minutes ago my roomate pulled iron from the plug and electrical fuse had conflict so power was loss in entire flat... When I turned pc again it showed me that start windows normaly option. So I concluded that it might not be power loss.
