Well i have came to a conclusion that the computer that I'm working on has a boot sector virus. Is there a program that i can use without having windows up and running to fix the problem. A program that is boot able ?.

Sorry i have posted three threads on this matter but really trying to get this working.... Thanks

What antivirus is installed as most AV's will detect booot sector virus.

smoker.

Some bios setups can be configured to prevent writing to the boot sector of the hard drive. This may be of some use against boot sector viruses. However, if you need to reinstall or upgrade the operating system, you will have to change the setting back to make the MBR writable again.

turn off write protect in bios.

go here http://www.avira.com/en/support/support_downloads.html

and download the boot sector removal tool from another computer if possible.

copy to floppy some how.

or get a live Knoppix or pclinuxos cd and copy files you want to keep to a cd/dvd or two. better still external hdd.

or use the OS install disk after turning off write protect in bios. best option?????

feedback please.

cheers ?

Sorry for the slow reply i was out of town... I got everything you said but i don't see a setting in the bios to turn the write protect off?. Would it be called something besides that... Also i tried the pclinuxos 2009 and i get a error saying can't mount the device... Thanks again for all your help here... Smoker :thumbsup:

Sounds like a hard drive problem...if you tried Windows and linux and both have problems with the drive, IMO.

I have put another hd in the system with no os on it but get the same blue screen when trying to load the os to the new hd...
This must be a wicked virus cause it even set a admin password as well that won't let me bypass...

Well...I would tend to believe that it's a motherboard/CPU/PSU, et alia problem...if it's common to two different hard drives.

But, I've been wrong before.
