thanks. The machine was working great. It was off about 10 days and then when
I returned that is the message I get. The error message that displays is
"Stop (000021a) fatal system error. Sytem error. f 0x0000005(0x0-). Also, I
can get to the administrator account in safe mode.
Something is apparently happening in regular mode that isn't in Safe
Mode. I just don't have enough information to know whether this is
hardware error (possibly something with the video card) or a software
issue. Here are some things to check to hopefully narrow it down:
1. Is the computer completely virus/malware-free? Go through these
general malware removal steps systematically -

You will need to get the tools and updates you need for the malware
scans from a known-clean, working computer with an Internet connection
and save the tools/updates onto a USB thumbdrive or burn them to CD-R.
Since you can get into Safe Mode, you can run the scans there. It is
preferable to do malware scanning in Safe Mode, anyway.
2. If the machine is clean, then do clean-boot troubleshooting to see if
something starting with Windows is causing the problem:

3. If neither #1 or #2 is applicable or changes anything, perhaps it's
time to turn to hardware testing. Since you say the machine has been
sitting turned off, I'd carefully clean out any dirt and dust bunnies
with compressed air. Then reseat the video card, any other PCI cards,
and the RAM. Here are some general hardware troubleshooting steps:

Standard disclaimer: I can't see and test your computer myself, so these
are just suggestions based on many years of being a professional
computer tech; suggestions based on what you've written. You should not
take my suggestions as a definitive diagnosis. If you can't do the work
yourself (and there is no shame in admitting this isn't your cup of
tea), take the machine to a professional computer repair shop (not your
local equivalent of BigComputerStore/GeekSquad). If possible, have all
your data backed up before you take the machine into a shop.
