my display driver messed up my desktop and im trying to go into safe mode to fix it but safe mode wont show up. IM running windows vista.. i keep tapping F8 when it boots and nothing shows up. I also tried holding F8 no luck either..Since my display driver is messed up could it not show the writing for safe mode. Becauce when i tap f8 or hold it it seems to give me a longer black screen then usually
