Hi forums. 1st post here and as the topic suggests I'v been having problems with BSODs for the last few weeks. Its usually caused by a SYSTEM SERVICE EXCEPTION or BAD POOL HEADER or CALLER. Usually happens at start up, but does not seem to have any obvious pattern. (will restart 1-20times then becomes stable until next restart.) I'll try and include the minidump files and if anyone can offer any help or advice I would be very grateful! (I dont know my way about computers too well either I'm afraid, so will probably need to be spoon fed!) Thanks for any help, Stuart.
