I have had an old Dell Optiplex GX620 sitting around for about a year not running. It had a few modifications made back in the day, new extra RAM and HDD's but worked like a charm until I got a laptop and stopped using it. I tried to turn it on a few weeks back and it didnt work, went to some bluescreen, so I opened it up and blew all the dust out just today hoping this might rectify the issue as it was pretty darn dusty in there.
It runs windows xp 32bit, 2 gig of ram, pentium 4 3Ghz, 280W power supply.
When I startup it goes to the black screen prompting to start in safe mode or in last known successful startup profiles. Whichever option I try it has a long list of files that then run down the page (checking fo rdrivers I think) until it finally reaches a blue screen which displays the following;
STOP: c0000218 (registry file failure)
registry cannot load the hive (file):
or its log or alternate.
It is corrupt, abscent, or not writeable.
