hi
i have a

Parkardbell easynote
Vista Home basic
1 gb ram
140gb memory

every thing was fine up untill 2 weeks ago when i got my 1st blue screen, i ran start up repair an returned laptop back to it original factory state..
yesterday i was installing new windows updates an i got a new blue screen crash
i get the option of launching start up repair or starting windows normally..



start in windows normally results in a blue crash screen

this time around launching start up repair is different, i still get the white bar saying windows it loading files,but when the bar is filled it trys too boot up windows normally again resulting in a blue screen again
the error message i get is

stop: 0x0000007E (0XC0000005,0X8471E0AE,OX8514FBA0,0X8514F89C)
volsnap.sys - address 847270AE BASE AT 84722000, DATE STAMP 47918F92

I still have the option of pressing f2 or f8 when u turn it on
Everything on the safe mode option screen results in the same error

is there another way i can launch start up repair or any other ideas of fixing this?
i dont know much about computers an would appreciate any help.. thanks

p.s id didnt come with a disk

thanks but this is no help..

i cannot access any part of laptop
as i said i only have access to f2 an f8 bios options
safe mode options result in blue error screen


any more ideas?
