Hi, when I turn on my computer, it turns on and gets as far as the 'windows is loading' screen then just restarts again... it just keeps doing this over and over! any ideas?

Do you get any sort of a blue screen?

Is there any sort of error code?

When you boot your machine, press F8 (Not F and 8, the F8 key along the top of the keyboard) to bring up the XP boot options menu. Select "Disable Automatic Restart on System Failure".

When you reboot, you may get a STOP error screen. Please post the error code you get. It should be 8 hex characters, ie. 0x???????? (Where ? = 0-F )

Good luck,

Thanks very much for the reply! Hmm I just tried to do what you said but this time it started up! (1st time in about 15 attempts!) I'm still a bit concerned though, it seems quite slow and always sounds like it's thinking even when no applications are running or snything. I have avg anivirus and antispyware. Anything you can think of that would cause this?

Hello again, vundosucks. (and it really does)

Can you export the "System" event log and send it to me?
Follow these instructions:
Open a run prompt and enter the following:
compmgmt.msc
On the left pane you will see an "Event Viewer" node. Expand this.
Right Click on "System" inside of this node, and select "Save log file as...."
Save it to your desktop
Then go to http://billy-oneal.com/fileUpload
Browse to the exported file on your desktop.
Enter your BC.com username where indicated.


!!!!! DO NOT REBOOT IF AT ALL POSSIBLE UNTIL I GET BACK TO YOU !!!!

This seems relevant to an error with uninstalling programs, see here: http://support.microsoft.com/default.aspx?...b;EN-US;Q328213

But I do not think that is the case here.

Please look in the following directory (it may not exist)

C:\Windows\Minidump

Send me the most recent file there (with http://billy-oneal.com/fileUpload ) , if the folder exists. At least that should remove software from being the problem.

Thanks for the dump. This is the analysis of the dump. It indicates some sort of hardware problem.

*******************************************************************************

UNEXPECTED_KERNEL_MODE_TRAP_M (1000007f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault).  The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
		use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
		use .trap on that value
Else
		.trap on the appropriate frame will show where the trap was taken
		(on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
Arguments:
Arg1: 00000008, EXCEPTION_DOUBLE_FAULT
Arg2: 80042000
Arg3: 00000000
Arg4: 00000000

Do you know how to burn an ISO file?

Download the latest version of memtest from here in zip format: http://www.memtest.org/#downiso
Unzip it.
Burn it to a cd.
Boot to this disk, and let it run overnight.

See if any errors are reported. They will appear in the bottom of the window in red.

Good luck,
Billy3
