Windows close and a blue page with white writing on comes up on screen, before you can read the fisrt line the computer starts in normal mode. it seems to work ok until the next time the same thing happens. Allan McMullin

Hi i have the solution to ur problem it's basically when ur windows file gets corrupted u will observe this sort of error message like what u have described a blue screen i recommend to install a fresh version of windows u can do this without losing any of ur critical data just follow these steps:
STEP 1:as soon as ur PC starts and u observe the logo on ur screen for e.x(INTEL,MERCURY) domething of this kind press F 8 immediately and u will see the next thing on ur screen is the PC asking to on ur system or load windows by providing some options select the option containing my msot recent settings that worked and ur windows will load surely without any blue screen error
STEP 2:as soon as ur windows will load try backing up ur critical data in a separate drive other than the drive containing ur windows files and folders and then install a fresh copy of windows or u can also repair ur previous windows using windows boot CD.
was this helpful to u if yes pls do rate my solution and thanks for visiting fixya.
NOTE: if the option u select do not work try other option specifying to load windows with all files and folders this will work sometimes but the above option works 99% perfect and if u face any problem just insert the windows boot CD and try repairing ur previous version of windows.
