HI, I have a 2.5 year laptop computer. It is an acer Aspire 4730zwith windows Vista. Lately while I'm surfing the web or doing other computer workit will just turn off. It's done this 5 or 6 times the past few weeks. Three times alone yesterday. I tried running malwarebytes' and fell asleep while it was running. When I woke up a couple hours later, of course it was off. Of course when I restart it, it say's do I want to start windows normally. I don't know what to do or how to find out what might be causing this abrupt shut down. Do you have any ideas what might be causing this and how I should fix it? Thanks in advance.
Response: remove all covers you can from the base give a blow out of whatever you can get at. Follow ESD precautions by grounding yourself by touching the metal frame of the computer every 30seconds or so when working inside the comp.
you said it happened in safe mode while scanning with MalwareBytes. So it's not only while surfing the web?
Although I'm guessing it's a hardware issue the fact that you couldn't complete a malware scan raises a yellow flag. I'd suggest you post in the Am I Infected forum to rule out malware. If indeed it is NOT malware, it's almost certainly a hardware issue of some sort since it also happened in safe mode.
Please let me know if you need more information. I appreciate you time and help.
