BBoD Again...

So i was hoping that it wouldn't keep showing up, but 3 bbos this month, i figured i'd do something about it...

I ran AV & MW removals, nothing...
i used CCleaner for registry clean...
and still...

1 time i was playing starcraft 2
this last time (10 mins ago) i was watching a show streamed... so im thinking its something with my video card maybe? but its a new one... just had it replaced like 1 month ago (fan quit working, but it's not that)

So a little help please?

Win7 64x
ATI Radeon 4870HD
4gb Ram
1TB HDD

Thanks in advance!

Also on the Event Viewer... there's this...

I'm confused... i got an 850w power supply... it shouldn't be it... is it??
Also i got a good power surge protector, i don't know what else... i didn't hit the button or anything... also it seems that its the same error that's been giving me the bbod... the dates seem right for all of them.

Hi,

Don't worry, let's work on it step by step

First of all, can you please remove Zone Alarm completely from your system. I've seen so many BSODs caused by third party Firewall and Zone Alarm in particular. Also, NETIO.SYS was blamed, it usually happened when third party antivirus or firewall is the cause.
Use this tool to remove it:
ZoneAlarm uninstaller - removal tool available - Windows Help Forum

Here is the usual cause of stop code 7F:

STOP 0x0000007F: UNEXPECTED_KERNEL_MODE_TRAP

Usual causes: Memory corruption, Hardware (memory in particular), Installing a faulty or mismatched hardware (especially memory) or a failure after installing it, 3rd party firewall, Device drivers, SCSI/network/BIOS updates needed, Improperly seated cards, Incompatible storage devices, Overclocking, Virus scanner, Backup tool, Bad motherboard, Missing Service Pack

Next, please update this drivers:

<---See if you can update this one, I think it might be the newest one possible
