Installed nfs2 now computer wont start

[mnewell]

Hi all

Ok so a friend of mine brought a wiondows 7 system from a local cheap shop. he tried to install NFS2 successfully and went to play it and now the computer wont reboot.
Sometimes it does and I get to the desktop other times I get the dreaded blue dump screen.

HELPPP

Thanks

Michelle

When you boot up the PC, boot it into safe mode.
Keep it like that. Check if the BSOD appears.
Also, does the BSOD happen all the time ? Like between constant intervals like 5-10 mins of use ?
