I had PC that was infected with a boot virus. I no longer have the HD for that computer. Is there anything that would still remain on the mohterboard or ram that would infect a new one if I got another HD. Or could the ram be installed in another computer?
Thank You

No, certainly not.
No need to buy new HDD just because of boot virus.
Download Slax linux (or ask friend to do it for you). Burn it and boot the machine from CD-ROM. Slax will load even without hard disk so this is the whole trick.
Boot with it and format the infected disk in Full mode (if there is selection).
I don’t think boot virus could survive such action.
In case if this fails somehow, get a low-level format software from your hard disk vendor and do a low-level format (it will be also accessable through such booting process).
Sure you’ll lose the data but you won’t have to buy a new HDD just because of this 
RejZor, can’t he boot from an old DOS floppy, uses FDisk to delete the partition, use the command line:
fdisk /MBR
to delete the Master Boot Record
Then create a partition, format, etc.?
Yeah, but i found Slax to be much better and more flexible tool.
I keep Slax on that small 8cm CD for such cases. And it saved my ass when IDE bus drivers went rogue on me. Got BSOD no matter how i booted. So i used Slax, burned backup using K3b burning tool in Slax and format the drive. All i lost was some time 
Thanks I am going to try the Slax method.
