This occurs just after I log into Windows 7 Home Premium.
Does any body what this means and how to resolve the issue?

This is likely a malfunctioning driver activated as it occurs after login, or do you experience randomness?
Please read this article to troubleshoot your BSOD, try to see if Safe Mode works and check the Event Log.
If you can get there, please upload the dump file so we can analyze for you which driver did this.
Not checking the crash dump is trying to fix a problem without knowing what the problem is.
So, you can try to remotely obtain the crash dump file, it is located at one of these two paths:
The best way would be to connect the hard drive to another computer...
The driver that is crashing your computer multiple times is
mfehidk.sys, from McAfee, your virus scanner.
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e) This is a very common bugcheck. Usually the exception address pinpoints the driver/function that caused the problem. Probably caused by : mfehidk.sys ( mfehidk+188e9 )
If we list the module, we get:
fffff880`03ab2000 fffff880`03afba00 mfehidk T (no symbols) Loaded symbol image file: mfehidk.sys Image path: \SystemRoot\system32\drivers\mfehidk.sys Image name: mfehidk.sys Timestamp: Fri Jul 31 23:59:58 2009 (4A73695E) CheckSum: 0004F637 ImageSize: 00049A00 Translations: 0000.04b0 0000.04e4 0409.04b0 0409.04e4
It's April 2011 and that driver dates back to July 2009, that's horribly out of date for a virus scanner.
If you can get into safe mode you can try to remove the virus scanner, if not you could attempt to rename
C:\Windows\System32\drivers\mfehidk.sys so that the operating system should not load it anymore.
There are ony two dumps mentioning the
iastor.sys driver, which is related to your hard disk. This makes sense as either the virus scanner driver or the hard disk driver is accessing memory in such way that the other one can't write to it, as a virus scanner scans files but this one seems to do it too early...
See how both dumps have problems reading or writing the memory:
ERROR_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx. The memory could not be %s. DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1) Arg1: 00000000000007e1, memory referenced Arg3: 0000000000000001, value 0 = read operation, 1 = write operation Arg4: fffff8800112a4ff, address which referenced memory
So, the steps to take are:
Prevent the virus scanner from loading, with either safe mode or by renaming the driver.
This will verify if the virus scanner is the culprit.
If it's not the virus scanner, do a error scan on your memory and hard disk.
As you are crashing on the
iastor.sys only now, I've looked at its date.

If I look at mine I see this:
So, updating your Intel Rapid Storage Technology drivers might fix your issue.
Uninstall any Intel Matrix RAID and Intel Rapid Storage Technology drivers first if possible...
This is likely a hardware problem. It is very difficult to determine because it is a generic-enough message that it could be any number of subsystem components - graphics, CPU, memory failure, hard disk or controller, etc.
My first suggestion is to run Memtest, which will test the stability of the memory subsystem. Usually if you're able to get through this your CPU has a good chance of survival as well.
Next would be to see if Windows boots into Safe Mode, by hitting F8 before Windows starts up (just before the "Loading Microsoft Windows" appears on bootup). If you are able to successfully get into Safe Mode, you can start trouble-shooting other hardware components by enabling / disabling or uninstalling / reinstalling drivers.
Had this happen and diagnosed the problem for weeks. Eventually read a few posts in the darkest corners of the web which gave me some hope. Took my laptop apart, dusted it thoroughly, removed the very hard and dry thermal paste off the CPU, GPU and chipset and replaced with fresh paste. Booted, working, no more issues.
Before doing the above I ran every benchmark and memory test I could find. Downgraded my video card driver to the standard windows driver, disabled network cards and anything else i did not use. Booted into safe mode etc... trying to determine where the problem lay. Checked the thermals on my laptop, looked good within specifications. None of this helped though.
