HI guys. I had a common problem happen to me yesterday that i have fixed before. Its theold one windows/system32/config/system missing or corrupt, where you use your recovery console and boot disk to replace the files. i wasnt too worried and went to do this. Big problem though... I opened up recovery console, and when you select the drive you want to log onto, i.e "1. C:\Windows" , i press 1, and get a BSOD. Same BSOD when i try a re-install. This is the Error that appears in the BSOD "REGISTRY_ERROR" blah blah blah blah advice "STOP: 0x00000051 (0x00000003, 0x00000001, 0x00003000, 0xE1295030)" The nasty thing is im unable to reinstall windows! nevermind recover all my files, which do include important coursework for school!!! the pc is completely inacessable, all i can do is go into bios(which im rather clueless about). Things i may look into doing: 1. Open up computer and reseat the memory stix and remove dust. i think this may be a memory dump problem or something similar. 2. A BartPe ultimate windows boot disk. I have no clue what this is but ive read about other people using it here, so i would like to find out more about this. Currently i have to use a 7 year old pentium 3 which has trouble loading msn messenger let alone windows! All help appreciated thanks!
