wont let me on sites that need usernames and passwords??? pls help

i cant get onto sites that need usernames or password, ie.. facebook or bingo sites.
i can get onto the page and put U&P in but when i press log in it jumps to white screen sayin can not connect to sever? im on a 3 dongle which works ok i have unintalled it and put it back on again just in case that was the prob, but its not my dongle.. any help would be great ive been trying to fix this for last 48 hours! x

sounds to me like either your security settings are set not to permit it, or javascript is broken on the machine
if you've not changed anything yourself, try using system restore to roll the machine back to before this happened

If this is a problem with Internet Explorer then you might well be able to work around it by installing an alternative web browser like Firefox or Chrome.

ok so i tryed the firefox like u said alan and it downloaded fine then when it loaded it said can not connect cos i have no internet but im on the net cos i just downloaded it!! and jon i cant do a system restore because i switched it off and on again and it wiped out all save points!! ( stupid move) so it could be the dongle or my setting i dont no any extra help pls cos im going mad with this.x

jon i think u might be right with security settings or javascript how would i check that?? it wouldnt let me download avg aswell cos it says im not connected but i am i can browse the web!? x

This is reminding me of the symptoms of a type of virus that changes your DNS server to another corrupt one. Typical symptoms are that you can access some web sites but not others, often not antivirus web sites for example, and it doesn't matter what web browser you use. You may also find that if you do an internet search then click on one of the links you end up somewhere different to where the link was supposed to be taking you. Antivirus software can find it difficult to detect and deal with this problem because often it hides very effectively by infecting a Windows system file. It's often the atapi.sys file that gets infected, but not necessarily. The virus might well be stealing your user names and passwords when you try to enter them.

If I'm right then the cure is either to reset your computer to its factory settings or call in a good computer engineer (i.e. someone with the nous to find and remove the virus rather than just reset your computer to its factory settings).

and if i restore to factory setting then i lose everything dont i?? can i save anything?

u sound bang on tho alan, i cant open norton aswell!?

is it not pos then to remove it by myself! lol, i only ask cos i dont know anyone who could come and have a look and i dont want to lose everything i dont have disks to reintall it all :(

Yes, a factory reset if very drastic action which I, as an engineer, only use as a very last resort. It's also a quick fix for computer engineers under time pressure or who don't really know what they are doing. You DO lose everything so you should first back up all your documents to an external hard drive or a memory stick or CDs/DVDs and be prepared to reload all the software that didn't come with the computer. You'll also lose all your settings, personalizations, stored passwords etc.

If you can pay for a repair then a PCIQ engineer should be able to visit and fix the computer for you. Follow the 'Get Support' link on the PCIQ pages.

Laptop computers often have a repair partition on the hard drive rather than disks, so a factory reset might still be possible if you know what procedure to follow.
