Thanks for your reply antikristuseke.
Here are my specs
Intel q6600 2.4ghz, 4gb ram 800mhz, mobo im sure is a p35 with pcie 1.1 (CPU,mono and 2gb ov ram are all thts left of a six yr old dell) cx 750 psu, 1 tb Hdd, gtx 650ti 2gb dcu2 boost pcie 3 and win 7 64bit. My plan was to upgrade CPU, mobo and ram which may well help (ive read tht diff pcie are backwards compatible but can still cause issues) however as ive just moved all my spare cash is tied up
. I did uninstall and reinstall drivers myself rather than GeForce expieriance doing it automatically but to no avail. I dont even have a working sh3 to fall back on :'(
