Windows 7: Multi BSOD's Physical Memory dumping & 0x7e & 0x1

Multi BSOD's Physical Memory dumping & 0x7e & 0x1

I'm currently having quite an issue with my computer at home.
I suspect a hardware failure, but it's not impossible to be software (virus?).

System Specs:
Core i3 530 (Clarkdale)
Asus P8 PRO Motherboard (Will have to check specifically which model it is, I'm at work now)
4GB G.SKill RIPJAW RAM (2x2gb dimms 1600mhz)
eVGA Geforce 9600 GT
Primary HDD 1.5TB WD
Windows 7 Ultimate OS

I can't get into windows in any form (normal/safemode) to run the SF Diagnostics Tool, so I cannot post any logs.

Here is what has happened.

Playing a game the computer froze, then went to a BSOD saying "Dumping Physical Memory".
Once the memory was dumped (0-100%) the computer reboots.
After this the computer would not boot up and just rebooted at random while loading windows. This would happen at random points during windows startup, sometimes it would reboot as soon as it started the "Starting Windows" screen, other times I made it to the login screen, and twice I actually made it to the desktop before it BSOD'ed and rebooted agian.
Safe-mode does the same thing, so I couldn't get access that way either.

I suspected bad RAM, ran MEMTEST86+ and found errors on 1 DIMM of RAM.
Pulled the bad DIMM and tried to reboot with the good DIMM of RAM (2gb).
Same issues, so I tried moving the good DIMM to the other RAM slots to make sure it wasn't the slot itself that was bad. Same issue.

-=End of Day 1=- (Haha?)

Popped my Win7 CD into the computer and started it up, thinking I could try and repair windows from the install screen. Nope.jpg
Computer reboots once the loading bar hits 100% (full grey bar) while trying to boot off the CD.
Tried a Linux boot CD (Koppix I believe?) to see if that would work. Nope, same thing! Once the loading screen for the OS appears the computer crashes.
Tried two Virus/Rescue disks (AVG and DrWEB) same issues, once the computer starts to load the OS/scanner it crashes.
Seems anything past loading the BIOs is failing.

At this point I tried booting into Win7 for the hell of it and noticed that the reboot now no longer occurs randomly, but always happens as soon as the "starting windows" logo appears. The BSOD I get is also no longer the "dumping physical memory" message but a 0x7e error (0x0000007e). I've also seen a 0x1 error msg (0x0000001). All "fixes" I've read about for these errors seem to assume you can boot into Windows in the first place, which I can't.

I've tried resetting my CMOS, but that did nothing.

My primary suspects are:
1) RAM
2) Motherboard
3) CPU
4) One hell of an issue with Win7 system files? But then why would the BootCDs fail... ehhh

-=END OF DAY 2=-

What are you're thoughts guys? I'm able to sit in the BIOs with no problems, no reboots, CPU temp sitting stable around 38-40 degrees C.
Quite confused by this point and I'm not sure what or HOW to tell which component is having the issues.

Thanks for reading!

You have hardware problems for sure if it's rebooting from the Windows DVD environment unexpectedly. Did you happen to run Memtest on the "good" RAM stick as well? Perhaps the "good" stick is just as bad as the bad one! If it's giving errors regardless which slot you put it in, the stick itself is bad, the RAM is just not compatible with the mobo you have, or the ultrarare case where all ram slots on the mobo are faulty. Make sure to check the mobo website to ensure both the model of RAM you have and the specs for it coincide with their compatibility chart.

Otherwise, yes, I recommend replacing hardware starting top-to-bottom from the list of suspects you provided.

Thanks for the reply!

I have not yet ran MEMTEST on the "good" dimm in all 4 slots on my MOBO.
I will try that tonight and see what happens.

I did however pull my HDD and connect it to an old AMD 64 3000+ system I had collecting dust! was able to boot up to windows and saw no problems with the HDD itself.

I was looking at replacement prices for my motherboard when I noticed that the i3 Clarkdales are a socket 1156 chip and so is my mother board (Asus P8H55-M PRO btw).
1156's has been discontinued and board choice is rather limited due to this.
So I'm either stuck with tracking down and buying a cheapo 1156 board OR I bite the bullet and replace my CPU+Mobo+Ram all in one swoop.

~$100 for a fix and continue running the same i3 Clarkdale CPU
~$350 for new 1155 Mobo and CPU (upgrading to i5 IvyBridge at this price)

Sorry, I know I'm getting a little off topic with this stuff for a Win7 forum.

Yes, this certainly not a HD generated problem. There are specific crashes for that. Instead, we're getting the usual variants caused commonly by some other component.

It's up to you which road you wish to go. If you urgently need a replacement then you probably want to go the cheaper route at this time. Don't forget to check RAM compatibility charts!
