This is quite a strange problem that started recently.
I turn the PC on, all is well, boot screen comes up within about 10 seconds or so after its done all the bios stuff as you would expect.
Then the windows user login screen comes up as normal, i put my password in, click on enter, the 'loading your personal settings' message comes up for about 5 seconds and disappears as usual.
Then my desktop background comes up, and thats where it all goes wrong.
All there is is the image itself, no start bar, no icons, no nothing, just the background image and the mouse, which i can move around the screen, but there is obviously nothing to click on.
I timed it earlier and it took 9 minutes and 36 seconds of this before windows itself came to life and the start bar and desktop items came up.
During this 9 minutes and 36 seconds there was no hard disk activity at all, as if no attempt is being made by my pc to load anything up whatsoever.
Once it finally came up there was plenty of hard disk activity and the disk led was flashing away as usual.
After about a minute or so of loading up.. AV, firewall, ad aware se, ATI control centre, etc.. the computer is running absolutely perfectly and there are no problems with it at all, it is in fact quite fast! (for a p4)
It is this big pause with no activity that is worrying me.
I am guessing that what is actually happening is that explorer.exe is not loading, or being prevented from loading for quite a long time somehow but i just don't know why.
If i boot in safe mode the big pause does not happen, it is about 10 seconds of waiting as normal.
Debugging mode (whatever the hell that is supposed to be) doesnt work, i get a black screen, and the mouse, which freezes totally and the PC hangs after about 2 seconds and thats how it stays. (i left it for an hour like this, got pissed off with waiting and restarted it)
These are the things i have tried so far to fix it, all of which have failed.....
* Removed all entries from the startup section of MSCONFIG apart from those needed for windows to run.
* Did a AVG 8 scan, no problems found
* Did a Adaware SE scan, no problems found
* Did a IObit advanced systemcare scan, no problems found
* Did a Spybot S&D scan, no problems found
* Ran DRwatson, no problems found
* Ran Ccleaner
* Ran JKDefrag, (HD not majorly fragged, but worth doing so i did it anyway)
* Removed all old or rubbish programs that i dont need or use much.
* Deleted lots of old stuff from my documents folders that i dont need anymore.
* Unplugged all devices apart from my keyboard and mouse (including disconnecting both cd/dvd drives from inside the computer)
* Thoroughly cleaned and removed all dust from inside the PC using 'henry the hoover'
* Removed GFX card, network card, ram and CPU fan, cleaned and refitted to make sure nothing was loose.
* Checked every single piece of wiring inside the PC to make sure its all properly connected, which it all was
* Fitted the spare big internal fan which i forgot i had got and wired it up for extra cooling.
Then i had my dinner, and a beer, and now i have truly ran out of ideas.
There is only one thing that i can think of that may have triggered it, possibly, as i managed to knock the PC over the other day by accident and it turned itself off, although if i had damaged some hardware then surely it would either not load at all or be permanantly slow??
I appreciate anyone who reads this massive post, and i thank you all in advance for any advice.
PS: LFS still works fine so not all bad!
