Can this error result from changes in services ?

As the Announcement posted at the top of this forum indicates, HijackThis logs should only be posted in our Viruses, Spyware, and other Nasties forum.

Right. I should have done that , but i think this has got nothing to do with virues or spyware .

Thanks,

Prakhar

Neither do I, actually.
I would start by having a look through your System and Application logs for any entries flagged as "Warning" or "Error". Such entries might help you narrow down the offending component(s). You can view the logs through the Event Viewer utility in your Administrative Tools control panel.

I checked the logs. Something is wrong. The last log recorded is like one month old and i have been using my pc almost daily

What should I do ?

1. That's definitely possible; why do you ask? If you made adds/removes/changes to your services or any other software components just prior to the problems occuring, please give us the details.


2. Without the logs, finding clues will be difficult. I'd suggest you start by running the System File Checker (SFC) utility and see if it finds any missing/corrupt system files or other inconsistencies. More info from Microsoft on the SFC is here.
