Hi My computer has a boot virus that is not detected by any virus scanner. My bios virus protection detects a boot virus but can fix it or identify it. It puts different coloured blocks of colour all through parts of the screen during load up, and will randomly shut down, and freeze. It also stuffs up directx games and programs in windows. My other partion of linux gets no effects. I believe this virus travels by disk, because the disk drive lights come on at unusal times. I cant find any unusual files on my harddisk or any odd things in the sis ini and wiin ini files so i cant send nod a sample of the virus. I also I believe i have had this virus for alot longer than it has been doing very noticable things and that it survived a format by placing itself in my graphics card memory,(winfast A380 geforce 4 ti4200 chipset) i tried doing a graphics bios flash and reseting the memory of the card but no such luck, and this virus is really restricting my computer in alot of ways. It sometimes takes up to 20 reboots before i can get it into windows successfully. I would appreciate any help. Thank you.
