Bros,

i have a asus engtx460 768MB gc which was running superb.

after the latest driver (335.23) update thru geforce experience, my display has this weird green lines and win7 aero is disabled.
device manager shows the gc with error 43.

i took the gc apart (no warranty d), cleaned the heatsink, removed old paste and added new thermal paste, and put it back...same issue.
then i rollback driver, still same issue. all the drivers dont remove the green lines even win standard driver

but if i use the mobo graphic card its ok but no aero la.

i never has problem with any component in the pc, all mantap. MW3 can play online no lag, full HD movies cantik.

can someone help me and tell me what can possibly be the issue? or any other steps to try.Thank you bros

PS: also i heard this card is the anak tiri of the gtx460 cards from asus - http://www.asus.com/Graphics_Cards/ENGTX4602DI768MD5/
