Hi,

My PC running Windows 7 ultimate is restarting automatically.

I already unchecked the automatic RESTART option from system settings.

Also, I disabled wakeup on lan option on my network adapter setting.

But, still PC starts automatically without blue screen.

I found out that most of the time, it restarts when I run videos or heavy applications like android studio.

Also, sometimes it restarts many times at interval of 1-2 seconds.

Anyone knows what is happening?

PC configuration:

i5 processor,
H61 motherboard (ECS)
Ram: KINGSTON- 8gb
hard disk: seagate 1TB
Network adapter: Realtek inbuilt



thanks in advance.If you've unchecked automatically restart it could be any number of things. First heat, have you recently checked the interior for dust? If not, you should do that first. Other possibilities:

1) Power Supply

2) Ram (run memetest to CHECK)

3) HD (download & run the hd manufacturer's diagnostic utility)

Those would be my initial thoughts.Hi Allan,

I checked Ram and dust.

By Power supply do you mean SMPS?

thanksI don't KNOW what smps is.

I mean your power supply. If you happen to have a spare one that you can try, you might want to do that.
