First of all I was getting bad pool caller error

That stopped and the pc (lenovo ideapad z570 Windows 8 64 bit) then started to restart itself in the start-up sequence every time and come up with a 'I had to restart so I want to send Microsoft a message' strip across the middle of the screen every time

Now it just doesn't start - goes to black screen - so I re-start it using the on/off button and it seems to be OK

Please can you help?

Many thanks

A bugcheck (BSOD) is a mechanism to protect your PC from damage.

Bug Check 0xC2: BAD_POOL_CALLER

http://msdn.microsoft.com/en-us/library/ff560185%28v=vs.85%29.aspx

The BAD_POOL_CALLER bug check has a value of 0x000000C2. This indicates that the current thread is making a bad pool request.

To see the cause I have to take a look at the dumps with the Debugging Tools for Windows.

Please start the Windows Explorer and go to the folder C:\Windows\Minidump. Next, copy the dmp files to your desktop, zip all dmp into 1 zip file and upload the zip file to your public Skydrive [1] folder and post a link here.

If you can't see dmp files, make sure your Windows is configured correctly [2][3] to generate dumps.

If you want to analyze them your own, check those videos [4][5]
