BDOD when playing Heroes of Newerth,error 0x00000050

Welcome,

Don't get pissed. Keep calm and eat aam.

See the usual causes for the BSoD bug checks:

Code:

STOP 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA
Usual causes:  Defective hardware (particularly memory - but not just RAM), 
Faulty system service, Antivirus,  Device driver, NTFS corruption, BIOS
BugCheck 50, {fffff800010ab10d, 8, fffff800010ab10d, 0}
Could not read faulting driver name
Probably caused by : ntkrnlmp.exe ( nt! ?? ::FNODOBFM::`string'+4514f )
------------
STOP 0x000000E3: RESOURCE_NOT_OWNED
Usual causes:  Device driver
BugCheck E3, {fffffa800700a390, fffffa80058903f0, 0, 2}
Probably caused by : ntkrnlmp.exe ( nt! ?? ::FNODOBFM::`string'+1a3e3 )

BugCheck BE, {fffff880041490ac, 18c0000115400121, fffff88005f818f0, a}
Probably caused by : ntkrnlmp.exe ( nt! ?? ::FNODOBFM::`string'+40434 )
------------
STOP 0x00000124: WHEA_UNCORRECTABLE_ERROR
Usual causes:  Hardware, Incompatibility, May be driver corruption
BugCheck 124, {0, fffffa8004b43038, b6000000, 181}
Probably caused by : hardware

Suggestions:
Please uninstall Avira Antivirus, it's known to cause BSoDs on some systems
Download and install Microsoft Security Essentials instead (or at least to test)
→ Avira AntiVir Removal Tool - Download
→ Microsoft Security Essentials - Free Antivirus for Windows

Run the System File Checker that scans the integrity of all protected Windows 7 system files
and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions
if possible:
→ SFC /SCANNOW Command - System File Checker

Run Disk Check on your hard disk for file system errors and bad sectors on it:
→ Disk Check

Let us know the results

I wonder why you're having storport.sys as BSoDs
Go through these links for ideas
Urgent Help please! system dead! - storport.sys - Vista Forums
The storport.sys driver leaks nonpaged pool memory when volumes are scanned, mounted, or dismounted in Windows Server 2008 and Windows Vista
You randomly receive a "Stop 0x0000000A" error in Storport.sys when you start Windows Vista

Does your motherboard have a onboard VGA slot?
Connect your PC there and see how your computer performs

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: fffff800044303e8, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, bitfield :
	bit 0 : value 0 = read operation, 1 = write operation
	bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff800033f6558, address which referenced memory

Yes but they must relate or give you ideas as well
Did you connect to your onboard VGA? What's the age of all your computers hardware?

You need to change the settings from the BIOS (Connect back to your graphic card first, go to the BIOS and change the settings, turn off your computer, connect to the onboard slot then power on)
It should be something like "IGD" or "INTG" something like that in the video/graphic settings of your BIOS
Is it still under its warranty?

Okay..were you able to connect through onboard VGA?
And since when are you having these BSoD problems? Is it from the time you got this computer?
I've done some research on the similar BSoD you're getting..and most of them pointed towards hardware
