BSOD several times a day...

Welcome to SF!

Please upload your dmps for analysis. https://www.sevenforums.com/tutorials...-analysis.html

I looked at your last four dmps. All four are indicating hardware problems.

STOP 0x0000008E: KERNEL_MODE_EXCEPTION_NOT_HANDLED

Usual causes: Insufficient disk space, Device driver, Video card, BIOS, Breakpoint in startup without having a debugger attached, Hardware incompatibility, Faulty system service, 3rd party remote control, Memory

STOP 0x0000000A: IRQL_NOT_LESS_OR_EQUAL

Usual causes: Kernel mode driver, System Service, BIOS, Windows, Virus scanner, Backup tool, compatibility

BugCheck A, {34, 2, 1, 82ca6028}

*** WARNING: Unable to verify timestamp for lserial.sys
*** ERROR: Module load completed but symbols could not be loaded for lserial.sys
Probably caused by : lserial.sys ( lserial+5f70 )

The two files listed in the bugcheck, ntkrpamp.exe is a Windows systems driver. I am certain that ntkrpamp.exe is not the cause of the problem. lserial.sys is an old driver dated 2007. Did you do a clean install of Win 7 or did you do an upgrade?

You have four more old drivers:

hardlock.sys Jul 27 2005 (this one is very old. It predates Vista)
nskbfltr.sys Jul 10 2007
vmm.sys Feb 18 2007
VMNetSrv.sys Jan 24 2007

Lets start with updating these drivers listed above. They should either be updated or the programs they are associated with should be uninstalled.

How To Find Drivers:
Quote:
- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.
- - Driver manufacturer links are on this page: Drivers and Downloads

Edited to add: lserial.sys appears to be from Lavasoft Ad-Aware Boot Cleaner and I thank Jonathan for finding this. I recommend that you uninstall this program using Revo Uninstaller. Revo will get rid of all traces of the program.

nskbfltr.sys looks like a keyboard driver.

In case you did not see my edit above:
