windows 7 uprgrade from vista - BSoD during start up

Hi I wonder if anyone can help me please? I have upgraded from Vista Home Premium 32 to Windows 7 Home premium 32. When I try to start in normal mode it crashes during start up. I have tried system restore but it does not work. I have tried disabling all non microsoft apps from start up and that does not work. I can only get going in safe mode. This is the error code displayed on the BSoD:

BCCode: 1000008e
BCP1: C0000005
BCP2: 8C451979
BCP3: A657F964
BCP4: 00000000

Anybody any ideas?
:cry

 

Check that you do not have any thumb drives, sd cards, etc plugged in..

 

You have to install win 7 from the begining ( do a clean installation ) , don't use upgrade method because some old files will be remain from previous ( vista ) installation , welcome !! :wave

 

Can Iuse the XP version that is on the installation disc or do I have to buy a complete new disc?

 

It's impossible using xp version because you would like to install windows 7 , two options : downgrade to xp for free or you have to buy a new one windows 7 disk , select one of them , what is your computer specifications ? :confused

 

In safe mode can you pull up the device manager...? click start>>right click on my computer>>click manager...when screen opens click device manager...Look for any red x's or yellow exclamations..
