My computer crashed, shortly after i had installed a new USB peg. Ever since then i cannot get into windows - i have tried starting in safe mode, the desk top flashed VERY briefly before crashing. I then triend to restore my registery - which it said it had done but when it rebooted it crashed just before loading again. Please help - how can i solve this? I have a master CD ROM, but it doesn't read this at start up - is there any way i can get into DOS and fix this? Having read through other similar problems, i think that maybe there is something wrong with my RAM drive, if so how can i fix this myself?
