I seem to have an intermittent but fairly frequent hardware problem.
I crash a lot, get many different BSOD's, sometimes a reboot with no BSOD, though
once (in Safe mode) the screen suddenly turned to a total garbage snow pattern...
no response to keyboard.
I pulled most components (optical drives, floppy, modem & sound cards) and crash still
Next, I disconnecting the hard drive, and ran Microsoft memory diagnostics off
the floppy. It has not yet crashed this way (and it HAS run twice as
long with no crash this way, as it ever ran when the hard drive is attached).
Thus, I suspect the hard drive, or perhaps the SATA cable or drive circuitry on the system
However, perhaps it's related to the video card (the only component i don't know how
to disconnect). The video card isn't tested very much in Memory diagnostic mode (only characters on the screen, no graphics, icons, etc.)
I have TWO questions...
1. Does my diagnosis so far seem reasonable? Are there other tests I can try?
I am now trying memory diagnostics (booted & run from floppy) with the hard drive
ATTACHED, to see if it is something like an intermittent electrical short from the
2. If I want to copy the whole C: drive (all of Windows XP SP2) to a new hard
drive (in case the old drive is faulty), what tricks must I do to get a fully bootable XP?
Do I need the old DOS "sys c:" or other tricks to get EVERYTHING (like the registry)?
Will I be in trouble if the new hard drive isn't the same size or geometry?
Do I need to use particular copy tools (not just drag-n-drop in the Windows explorer program)?
THANKS SO MUCH FOR YOUR TIME & ANY HELP!!!
PS. HISTORY - it's the 3rd time this machine started frequent crashes in 6 months...
First time replaced a bad optical drive, then it ran fine a few months. Then frequent crashes
started again (suddenly), eventually replaced power supply, ran fine for
3 weeks, now frequent crashes returned. I dont suspect the power supply since it's
new (and has higher watt specs than the old one).
