Laptop suddenly shut off no error, no bsod no restar. Kernel power

Hi, i really need help with my problem before i go to tech shop and get drained all my money

My laptop, windows 7 ultimate x64. Acer Aspire 4738zg suddenly shut off like the power been cutted off .

I recently got bsod with my graphic card and managed to fix it by updating the driver and with a clean format. Now another problem came up. After formatting my laptop works fine for about 2 days.

Then it suddenly shut off by itself whem im watching hd videos, surfing web or anything else within a period of time.

Ive been monitored the temp. The cpu temp were in normal temp (60c-70) even when multitasking with Hd vids, hd youtube, but the gpu is slight hot when im stressed it with multi tabs of hd youtube and vids (up to 95c) but it doesn't occur yet .then i closed all the task and surf the web or doing anythg else, then it shutt off with no restart,error,bsod

Btw my battery is out (consider replacing your battery).
Driver up to date.


I went to event viewer. It say kernel id 41 task 63 level critical.

Excuse my english and writing. Im a newbie and Im typing with smartphone right now as my laptop got this problem. Sorry.

AFAIK that only means that the last shutdown was not clean. Which you already know as it was quite sudden.
Can you reboot after the shutdown?

Hi , thanks for you reply . Oh i see . and yes i can still reboot. Right now , ive already reboot and do a system restore . From the last an hour , its still working fine right now with no shut down . Im gonna monitor it for a while to confirm it because sometimes it happen right away , sometimes it dont , but it will at other time . Just like this .

Im still wondering what could be the problem because , i can boot into safe mode etc, sometimes its okay, sometimes it not . I had already search entire forum and other forum about this but still not find any answer to this .

Next time it happens try to boot again and see if there is an error in eventviewer before the unexpected shutdown. Unfortunately that is not always the case.

After 5 minutes i posted my previous reply . It happen again .Sudden power off . i rebooted , and went to event viewer , it show critical error(X) for event id 41 and error (!)with my previous shutdown was unexpected .

What could this problem be ? To be more specific , the PSU or GPU or Software level ? So i will be prepared when at the tech shop

If your GPU is overheating it might be just that. Are you using the OS the laptop was originally shipped with?

But sometimes it happen whether gpu temp is high or not. Im currently using windows 7 ultimate x64. My original shipped was windows 7 home premium.

Overheating remains a possibility. You are running without a battery so any problem with the power cord would lead to an immediate shutdown as you described. The last thing you could try before getting ready to open up the laptop is to post in System Security - Windows 7 Help Forumsand ask for help to check if you have a malware infection.

I brought my laptop for diagnose at the tech shop for free and found out that the hard drive is failing and it causing the power off. Could it be? I never thought the HDD would be the culprit. Need advice asap before i bought a new HDD.

You could test the drive yourself. Use a tool like Seagate Sea Tools. If you have a CD drive on that laptop I recommend using the CD version, if not install the Windows version. SeaTools | Seagate
