Windows 7: BSOD 0x116 AT START UP.

I hope that that was the problem. Wait a bit longer before declaring it "fixed".

Computer is working well now.No bsods even after playing half-life for continuous hours and the game is finished.

So,chip set driver was the culprit.

Thank you so much Sir John,for your quick solutions.

Glad to hear it!
Thanks for letting us know!

A very interesting question that came in via PM:
I see it fairly often, but don't normally do anything about it unless the user has some sort of problem that involves it.

Note that the error refers both to the engine (the core of the program) and to updates. I don't know if this is a terminology problem, but the first thing to do is to check and see if this error occurs after getting the latest updates.

If it does, then the "fix" is to:
- download a fresh copy of MSSE
- uninstall the current copy of MSSE
- install and update the fresh copy of MSSE
- immediately do a full scan of your system.

I have done all that things.

First I thought it might be a virus problem.So installed malwarebytes and superantispyware and found no issues.Then I uninstalled it and installed it freshly.Still there is the problem.Then I uninstalled it and installed it via Windows update.It didn't solve the issue.When I checked my laptop,the exact error is also there in the laptop.That is the strange thing.Then I called my friend who is also using the same antivirus.He is not a computer expert and I just him to check whether this error EVENT ID 3002 is present in Event Viewer.He told along with many errors,this particular error is also there.Not one,many.

Then I went to Google and searched.I noticed many people are having the same issue and this is a common bug in MSE or Windows.

When I contacted tech support of Microsoft(after posting here),they told it is a general issue and they are working on to resolve this bug.They told some bug both in Windows and MSE. Thats why it is reported in event viewer and told a false positive and no need to worry about it.Anyway MSE is working fine but this is strange!.

Thanks for the info, I had no idea that it was that widespread!

Till now,no BSOD occurred again.

Now,I am told that I haven't installed "all" the updates provided by Microsoft.So my concern is will it make any issues in future?
But I have installed all the updates and never let an update to be missed.(Except crappy drivers by Microsoft).Most of the updates or SP1 update,I have done via offline.ie I have disk of an SP1 update.How can I know all the updates are not installed eventhough Update service says Windows is up to date.
