Ok.
I looked at the 4 minidumps you attached and all of them are saying the same thing
Probably caused by : ntkrpamp.exe ( nt!HvpGetCellMapped+5f )
All four of your minidumps are 0x8E errors. These are nearly always hardware compatibility issues (which sometimes means a driver issue or a need for a BIOS upgrade -- though a BIOS upgrade, In my opinion, should be a last resort).
Dumps 1 and 2 have this
DEFAULT_BUCKET_ID: DRIVER_FAULT
BUGCHECK_STR: 0x8E
PROCESS_NAME: services.exe
Dumps 5 and 6 have this
DEFAULT_BUCKET_ID: COMMON_SYSTEM_FAULT
BUGCHECK_STR: 0x8E
PROCESS_NAME: services.exe
Before I can try to help you further I need to know some information...
System specs:
When the crash usually happens:
Around when did the crash start:
Did you add any hardware or software that you can recall when this started happening:
Also have you done a scan for viruses/trojans adware/spyware/malware all that icky stuff? I can't be sure what's happening until I get the info I requested..but here is something I found just with a quick search.
Services (1)
Services.exe
(Microsoft)
Windows NT4/2000/XP/2003 only. This is the Services Control Manager which is responsible for starting, stopping, and interacting with system services. It’s full path as shown in The Ultimate Troubleshooter is either C:\WINNT\System32\Services.exe in Windows NT4/2000, or C:\Windows\System32\Services.exe in Windows XP/2003.
Recommendation :
An integral part of the operating system, leave alone.
Services (2)
Services.exe
If, regardless of which version of Windows you have, this task appears on the Startups tab of The Ultimate Troubleshooter, then you most definitely have a virus such as the W32.Ahker.B@mm virus.
If you have Windows NT4/2000/XP/2003 and the full path to this program on the Tasks tab of The Ultimate Troubleshooter is
C:\WinNT\Services.exe
or
C:\Windows\Services.exe
or
C:\Windows\inetg\Services.exe
or
C:\WinNT\inetg\Services.exe
or C:\Program Files\Common Files\Services.exe or
C:\Documents and Settings\ <anything_here>\Services.exe,
then you also most probably have a virus such as the W32.Netsky@mm or W32.Neveg.B@mm or W32.Conycspa@mm virus.
got that info from this site
