BSOD in Windows 7 Ultimate x64. NETIO.SYS

My Machine Specs:

AMD Phenom II X6 1055T (2800 Mhz)

Corsair 4GB (2x2) DDR3 1600Mhz RAM

Asus M4A88TD-M/EVO/USB3 Motherboard

nVidia GeForce 9400GT 512 MB DDR2 Graphics Card

WD 500GB + WD 320GB HDDs



Problem:

My PC has been running fine for almost a year now, until a few days ago, I started getting BSODs while playing HON (Heroes of Newerth) or watching Movies in VLC player. First I thought it was a Graphic Card issue so I installed new drivers, nothing changed. Then suddenly I couldn't boot up in Windows. A black screen appeared just before the welcome screen and the PC Restarted. So I removed the graphics card and continued to use the On-board Radeon 4250 HD. Then I reinstalled Windows 7 Ultimate x64 (Clean install), and after it was completed my PC froze again. This time, no error, nothing. Just froze at desktop. I kept it running and started experiencing random crashes and BSODs. So I reinstalled my previous Graphics Card and then after a few days again, I got BSOD. So this time I used BlueScreen view to get the DMP file and the error was identified as :



KMOD_EXCEPTION_NOT_HANDLED it was caused by NETIO.SYS



Also a thing I noticed was, when I restarted my PC after it froze, during the BIOS, sometimes it said Overclocking Failed, please enter setup.

Now I haven't overclocked my system, but I've used Asus Core Unlocker to unlock 6 cores and sometimes, only 5 Cores are active after a crash (3rd Core was OFF).

These crashes are totally random. Please help me identify the problem. Is it due to overheating or any other Hardware issue. I've attached the DMP files here.

The skydrive link errors out. Please upload them here.

These were caused by a memory exception. Please run these two tests to verify your memory and find which driver is causing the problem.


1-Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

RAM - Test with Memtest86+



2-Driver verifier

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Driver Verifier - Enable and Disable

Thanks a Lot. It's solved. The problem was with my RAM. Even though MemTest did not find any errors.

One of my RAM Stick is giving the error. I tried to run the system on each individual stick and found the culprit. I'm sending it for replacement now.
