hello all,

Dell Dimension 8250 Pentium 4 , microsoft xp ( not sure on home or professional, as well as service pack , I'm guessing 2 or higher) will not boot up.

It gives me a blue screen stop error code

STOP: c000021 {Fatal system error}
The windows logon process system process terminated unexpectedly with a status of
0xc0000005 (0x00000000 0x00000000).
The system has been shut down.

I am reparing this computer for my sister , did some searching around , but i know computers are a case by case basis. i'm able to run it beside my via a seperate monitor , i just need help if anyone is willing!!


Thank you in advance , Justin
