Blank screen on windows startup, sptd error


When I try booting Windows XP, the Windows logo and 'Windows is now starting' screen loads normally, but then immediately afterwards the screen goes blank. There is no blue screen of death, no automatic restart, and in fact the hard drive is blinking. I tried booting up Windows in Safe Mode with Networking and no screen problems occur. I can't run Norton Antivirus while in Safe Mode.

Checking the events log, I found the same error for the several instances I tried booting up (source: sptd; event ID: 4):

'Driver detected an internal error in its data structures for .

Any image mounting software?

Daemon Tools

Yep, I do have Daemon Tools. I've been browsing various forum threads and tried following the methods but I still have the same problem. I tried deleting Daemon Tools within Safe Mode (couldn't properly uninstall it nor can I find it in Add/Remove Programs so I had to delete the folder and registry keys), disabling Daemon Tools in msconfig, disabling sptd.sys through editing the registry key(HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sptd), tried System Restore, but none of these solutions work. Any ideas please?

Find the daemon tools support site.

Sorry I don't have a procedure to remove that but I bet it's author or support site might. It appears to create problems and why we don't use it at the office.

Other event viewer errors

I also noticed these three errors popping out, not sure if they're relevant:

The intelppm is mildly interesting.

But only was an issue for HP AMD based machines. HP and others wrote what to do next.

Repair install, new BSOD error

I decided to do a repair install for Windows XP. Not having the original Windows XP disc with me, I used an OEM disc for my separate HP laptop.

After the repair install finished (the one with the DOS like screen and the progress bar), it automatically rebooted, and then I came across this error:

'IO System Verification Error in HIDClass.sys (WDM Driver Error 22e) [HIDCLASS.SYS + 18b2 at BA4328B2]'

I can't boot into safe mode as the setup process hasn't finished. This error didn't appear originally- is this the real source of my problem?

Sorry but using the wrong CDs was a mistake.

I've found that to be a fatal one as the OS is now more corrupt than before.

I suggest you save what files you need to save then start over.

I also suggest you heed the words in red when posting. For example there are issues with some HP AMD based units and that IntelPPM but you didn't address that or supply (if you did, I missed it) the make and model number.
