Thank you all for your replies, here is what has been going on over the last couple of days:
- As suggested by Alan, I have been running the defragger from IObits, its taking an awfully long time to defrag; but things are going on.
- Usasma: I have tried that and here are my notes: everything is normal till I click on any icon in the desktop to launch the application, that application will take up 100% of the system resources for about 90s-100s till it launches. Overall I have noticed though that my firefox uses much much more memory than it used to. I un-installed and re-installed but that didnt seem to help.
- Maximillian: I looked in the search folder and cleaned up all the un-necessary applications. I have worked with the registry before that was guided and the instructions were very specific, haven't modified the registry after that.
- Garmanma: very true
, I wont modify the registry yet, but will sure make a backup of it before I do so, thanks for the link.
for now, the defragger is running, will post back with my notes after that finishes. any suggestions in the meanwhile are welcome,
thanks a lot,
