Hey there,
First, let me preface this by saying I am really not sure if this is a hardware or a software issue, but there is no indication it is a hardware issue.
My wife's Dell Inspiron 1420 with Vista Home Premium SP1, 4 Gig of RAM has suddenly begun acting very strange.
Over the last few days she has received a couple of random BSODs, and several times the windows start error of "Windows failed to start properly, either a software or hardware change might be responsible" -- previously windows repair using the backup disk shipped from Dell fixed the problem. However, now neither that nor System restore will fix the issue. its simply a perpetual cycle of start/restart errors.
Safe mode doesn't work either, windows starts to load up, reaches the "crcdisk.sys" module and then hangs for a moment, and returns to the aforementioned error screen.
I downloaded a RAM check program, and she ran it (it was an autostart program with no OS load required) and it returned no errors on her RAM, so I'm fairly positive thats not the issue (that and the fact that safe mode hangs in the same place everytime).
My wife is a graphic design major and would like to avoid reformatting before she has a chance to backup her last few days worth of files -- any help or suggestions you guys could offer would be greatly appreciated.
