Laptop Shuts Down Suddenly

If it helps you at all my laptop (which is less than a year old) started running really slow and crashing and I took it apart and cleaned everything and now it runs really great. The fan and heatsink can definitely be an issue for slowing a laptop down. They can also ruin internal parts of a laptop such as the motherboard (but in that case, the computer would not start at all. It would just appear to be dead.)

Did you get your laptop to start again after you took out the battery and put it back in? and did the battery have a good charge when you last used it?

From the error message "application failure to initialize" that could mean many things but If you can get your computer started I would scan for malware / viruses. There are script files that can be placed in your registry to make your computer shut down after a certain period of time.

Other than that, I would suggest using your windows install disc to try to repair any problems, or if you can get to the boot screen, try system restore, or starting in safe mode and searching through the processes and applications running at startup.

Hope this helps somehow.....Good luck.

Just a thought: could be that one of the hardware connections was not reseated properly upon reassembly.  If the connections are imcomplete/barely touching you will have issues with unexpected shutdowns, so it would be worth you while to have them all checked out.

I think both G3 and starkers have offered good advice...starkers has helped me with stuff in the past with good explanations and he does build his own computers.

I think you should try G3's advice and if it doesn't help, take your computer to a reputable technician and have it well examined...

Good luck with it, Supe.

Yes It started back. Now its running fine after that hide-and-seek but I just want to make sure there isn't a short circuit bcoz I have to do all my work on it for at least 14-15 months.

I was coonected to internet but I could open only few sites.

avast, winmatrix forums and wincustomize forums and gmail.

Yes there was a registry problem few days earlier with 'Stop Error code c000021a' when I had installed ubericon 1.0.4 and iColorfolder. I mentioned it here https://forums.wincustomize.com/345931

But I had restored the whole disk image after that. So there should not be a single trace of it left.

I looked the processes at startup. The only dangerous is this...

But its Intel-manufactured. Should I disable it?

Might be true. He claimed to be an expert but I suspect. I asked him to please read the service manual. He said "Boy, I know everything." He gave my laptop three scratches on cover. I didn't say him anything for that though.

Also when he reassembled everything there were two screws left. When I asked from where these screws came he said " These screws are mine." 

I said " But they look like mine, please sir don't play with my laptop like a toy and place these screws at the proper place"

He said " Comon trust me nothing will happen"

I said "No I have to move it here and there. I can't lose two screws"

He said "Do you want me to reopen your laptop"

I said "What can I do? I have brought my laptop to remove the dust not the SCREWS"

He said "Alright I will do"

I said "thanks"

Then he removed the keyboard, looked if the screws were missing, then he looked down and wverywhere. At last he opened HDD. Alas! the screws belonged to there.

What a funny engineer "I know everything!" huh.

"Jack of LOL trades"

Sheesh...engineer? Sounds like a lazy, arrogant slob.

I say if you have a backup, try G3's suggestion. Then starkers...I'm betting that probably a combination of the two will fix you up.

I'd also say that sometimes you can get perfectly good files (and necessary ones) being identified by antiviral software as being potentially "dangerous". If you can identify the file as Intel, or obviously good, don't let the AV software touch it and put it in the AV program's "ignore" list. Also, don't let those programs do anything to files "automatically" except warn you.

Again, Supe...good luck!

I think both G3 and starkers have offered good advice...starkers has helped me with stuff in the past with good explanations and he does build his own computers WITH SPAM.

I think you should try G3's advice and if it doesn't help, take your computer to a reputable technician and have it well examined...

Ooops, bringing back an old thread I see. 

BTW, SpambaRobot, we can read your edits.

What the heck, now that ruffles my feathers!
