Windows 7: Unexpected Shutdown especially when turning on games

Unexpected Shutdown especially when turning on games

My computer randomly shuts down and reboots by itself. It's usually unpredictable but inevitable if I turn on a video game. I don't see any BSOD errors but just to be sure I decided to follow the instructions here and post. I hope someone can help me find the reason behind the shutdowns. I'm willing to bet on a faulty power supply but I need to be sure before investing in a new one. Btw, Event log shows the EventID 6008, as in "The previous shutdown at *time* was unexpected". I need to fix this problem urgently so please help me. Thank you.

Welcome to the forum taiyo

You think it might be a power supply problem but yet you don't list your power supply in your System Specs. It would be helpful if we knew what power supply you are using.

Take a look at my specs and it will give you a idea of useful information.

It would also be helpful if we knew what cooling your system has and what temps the cpu has with a load on it.

I use a Gigabyte Superb E720 GE-E720A-C3 PSU. As for cooling I use stock coolers with cpu and gpu and one fan that came with cheap Delux casing right under PSU.

Your picture show some poor voltages from the power supply.

Could you go into your bios and list these in your next post.

+12V ?
+5V ?
+3.3V ?

Also another picture of HWMonitor showing those voltages.

I'm not understanding a fan under the power supply.

Could you post a picture of the case with the power mounted or a website showing the case you are using.

The power supply should mount with it's own intake and exhaust ports. No other fans should be needed for the power supply other than what it came with. If their is anything blocking the intake or exhaust air flow for the power supply it will over heat.

I meant the fan at the back of the casing. Sorry I'm a major noob at these things. :/

Suggest you remove your Graphics card,clean out the motherboard slot,use a clean pencil eraser to clean the card contacts,then a lint free cloth dipped in methylated spirits to wipe over the card contacts.If the card has a cooling fan attached,clean the dirt from the intake and exhaust louvres and the fan also.confirm the fan works by blowing on it.Inspect the card for any discolouration caused by heat,in particular the capacitors,(large cylindrical objects) for any deformation,no lumps or bumps.This might help.
