After a boot sector crash, I formatted my hard drive and reinstall Windows 7 from scratch.
Although my laptop now takes ages to startup (about 10-15mins!) and after I'm logged in, everything lags!
This started after I rebooted my system for first time, after Windows installation and after some updates were downloaded and installed. What can be the cause of this?

I have seen it with very old Dell PC stations, getting new HDD helped.

Your hard drive is currently in the process of failing. The very long read times are likely because it is seeking for an extraneous amount of time due to either a damaged or badly off voice coil or a damaged platter resulting in difficulty locating tracking cylinders.
Immediately copy all of your important data off of the drive. It may fail entirely shortly and with no warning. In some cases, performing a thorough wipe of the drive (such as a Gutmann wipe) may actually restore functionality (I don't understand why), but I wouldn't trust this to last. Purchase a replacement drive, they're not very expensive.

^^ Take the above advice. Next, download one of the many free bootable OS on a CD, and see if boot time is dramatically different. This will (mostly) separate your concern -- is it HDD, or is it laptop? Have you run a drive checker? Some bootable OS CDs have techy utilities you can run to check out the laptop. – Robert Kerr – 2011-08-20T22:37:08.303

Sounds like HDD problems.
There are many software for troubleshooting these kind of things.
You can try HDDScan which is a freeware and rather good at finding problems with the HDD.

You might start it from a live CD/USB. A live OS won't touch your HDD, won't install anything but it might contain the tools to recover/examine the errors like HDD corruption or memory defect.
You can give a try:
*Hiren's Boot CD *Ultimate Boot CD * and many more..

I think this is a question for Superuser, as it does not seem to contain any questions about programming in general – wrongusername – 2011-08-20T22:15:03.123
