HI. running XP Home SP3 (updated recently) on a Fujitsu_Siemens laptop, my system will not start at all & gives me a BAD-POOL_CALLER blue screen with an error code of 0x 000000c2 (...) everytime just as Windows appears to have finished loading. I';ve tried the Fujitsu Recovery disc Repair option... it seems to hang at the C:\WINDOWS> command & don't know what to type next.
