As u know that when we search for a thing in any search engine it shows number of websites to choose from and we start hopping from one to other ofcourse there is no doubt that there are some gr8 websites which helps to minimise this hopping but can't prevent.one more such attempt is mine to minimise the switching and get a priority wise alignment of the total info available on net submitted by different users
my 1st topic: WHY MANY WEBSITES ARE NOT OPENING UP EVEN WITH DIFFERENT BROWSERS?
Check your Windows HOSTS file - Make sure there’s no entry in the hosts file that maps the website’s address to localhost or an incorrect IP address like 127.0.0.1 – it is a possibility if you have imported some third-party hosts file.
cmd /k notepad c:\WINDOWS\system32\drivers\etc\hosts
The hosts file is a computer file used by an operating system to map hostnames to IP addresses. This method is one of several methods used by an operating system to locate network nodes on a computer network. On many operating systems, the host file content is used preferentially over other methods, such as the Domain Name System (DNS). Unlike DNS, the hosts file is under the control of the local computer's administrator.
If you don't use special DNS-settings, you should clean hosts file.
Some programs (e.g. Spybot Search & Destroy, Ad-Aware & so on) change them to prevent the connections from your PC to the well-known bad sites.
The problem here is, that the quantity of bad sites rises prompter, as database update by security tools and the hosts file after 4-5 updates will be too large.
That is why we recommend you to hold hosts file as written.
Start HijackThis (http://www.tomcoyote.org/hjt/).
Choose Config... (down on the right side)/MiscTools/Open hosts file manager/Open in Notepad.
The file will be opened for edition in Notepad.
Delete all strings excepted
If the such string does not exist, you have to add it.
VERY IMPORTANT::: Additionally only for Vista/Windows 7
Pls. check/add the next string
::1 local host
: Find Faults in the Pipeline – Paypal website may be up and running but it is possible that the real problem lies with a router that is between you and the computer hosting the Paypal website. Do a traceroute and check for messages like “Request Timed Out” – they will help you find the location of the breakdown.
Type the following command in the Run Window:
cmd /k tracert www.paypal.com – remember to replace Paypal with address of the website that is unreachable.
: Clear DNS Cache – The DNS cache keeps a record of sites that you have recently visited on your computer. If that gets corrupted, you may have issues opening sites that were previously accessible without problems.
click start----select command prompt-----right click select run as administrator-----type cmd /k ipconfig /flushdns to clear the cache.
alternate:---Type cmd /k ipconfig /displaydns in the Run window to see the cache entries. If that unreachable website is listed in the cache, type cmd /k ipconfig /flushdns to clear the cache.

: Website May Be Blocked – The chances are rare but it is possible that access to some particular website may be have been restricted by the Office firewall. To test this, send an email to email@example.com with the problematic website URL in the subject field. If the website is up, you will get a text copy of the web page in an email message.
Suspend the Anti-Virus and Firewall – If you are running an external software firewall or anti-virus program (like Norton, ZoneAlarm, etc), exit and restart the web browser. Is the problem solved now ?
When nothing works, open 192.168.1.1 and reboot the modem. If that fails, restart your computer and as a final step, call your ISP support.
