G31M - ES2L Shutdown unexpectedly

[zecter]

Hi, there... I'm just a newbie in this forum and wanna say hello to all forum user.

Btw i wanna ask some questions, I just brought a new PC with G31M-ES2L  as a mainboard. I'm tried this new baby with some games, but suddenly after I played the games my windows was shutdown unexpectedly. It's just like normal shutdown but without I'm ordering it to shutdown. I tried to turn on my PC but only after POST messages my PC was went off again. It seems like it's doesn't enough power.

I opened the case, and tried too look what is wrong, but everything was in order. I turn on my PC, but it's happen again but with worse messages. My BIOS was broken! Thx to Gigabyte dual BIOS, my mainboard try to fix this thing automatically. But when the repair almost finish my board were went off again. And suddenly the board went on, report the same problem, try to fixing it.... went off again. went on again ... and went off again. wew....

Unintentionally I touch my board chipset (the heatsink in the middle of main board with gigabyte sign on it). Whooa... the heat... it's seems to burn my finger already! Ok I know Intel chipset can quite hot but not this hot!

The questions I wanna ask is, does my board broken? I bought my PC a week ago, and i'm only play it for only 3 days! Except for the optical drive an computer case, everything was new. And the 2nd question I wanna ask is if my board was broken what cause it? Power shortage or does it not enough power to my PC coz I'm using 500 w PSU.

Btw This is my PC specs

Intel E 5400 2,7 Ghz
Gigabyte G31M-ES2L 
Seagate 500 GB Sata
Pixel View GF 9500 Gb
Memory 1 GB PC 6400
1 DVD RW IDE
1 DVD ROM IDE
PSU Simbadda 500W

Btw sorry for my bad english.... Thx 4 your reply

Hi and welcome to the forum
It sounds like an overheating problem and from whatb you said about the northbridge it would confirm this. Is this a self built computer or did you purchase it made up? It  would appear that there is not enough cooling in the case especially around the motherboard area. Can you post some more details.

Overheat? Hmm... it would sound fair enough. I'm using standard cooling system (cpu fan and 1 system fan, off course there was vga fans. Oh yeah since that accident i open my computer case and never close that case anymore). Yup I build this comp by myself, not a branded one ( It's to expensive to me for brought a branded PC  )

Btw sorry for my foolishness, but can I ask what detail information do you wanna have regarding to my case? Thx for the reply

As much information regarding the components that you installed when you built the computer as possible. Case, fans,  psu, mobo,  chip, ram, graphics card, drives etc, you get the idea. It's just the more information we have access to the more complete picture we can build up regarding your problems.

When you built the system did you set bios to load optimised default settings then reboot? If not do so now. Have you set voltage settings for your Northbridge or is it on auto?
