Windows 7 - Random BSODs almost daily, Bluescreenview blames ntoskrnl.exe

Hello. I'm not very tech savvy, so please bare with me while I try to explain my issue.

For about 2-3 weeks now, I've been experience random BSODs. After trying several things, I decided to reset to factory last week. All was well until a few days later, it continued with another BSOD. Ever since then, I've been getting them at random. Sometimes it'll happen 10 minutes after I boot my computer, other times it could take a day or so.

I download Bluescreenview in hopes that I could find what was causing this issue and get it resolved.
Bluescreenview stats that the bug check string is: KMODE_EXCEPTION_NOT_HANDLED
caused by driver: ntoskrnl.exe

There are other crashes where the driver was hal.dll and win32k.sys.

I'm not sure how to post my MiniDump files, I've tried accessing them, even with the Windows Debugging tool, but it says I don't have permission to open the file.

Information about my system :

Windows 7 Home Premium 64 bit
Acer Aspire X3400
4 GB ram (3.75 GB usable)
Processor: AMD Athlon(tm) II X3 435 Processor 2.90 GHz
Service Pack 1 is installed.


Any help, suggestions or assistance would be greatly appreciated.

Blue Screen of Death (BSOD) Posting Instructions

Seems like hardware errors
Run a RAM test
RAM - Test with Memtest86+

Run Prime 95 to test your CPU. Carefully the instructions in this tutorial: CPU - Stress Test with Prime95. Run 3 separate tests, one on each of the settings (Blend, Small FFTs, Large FFTs). Post back with your results.
Note that this test may overheat the CPU, ensure proper cooling

Hey,

I ran the Memtest86 for 7 passes, took me about 7 hours but no errors were found.

I followed the steps listed and there should be an attached file that contains the System Health Report, including the Dump files.

I haven't done the Stress Tests yet, as I thought I'd give you these files first and see what you thought was the best course of action now that you have more details.

By the way, just thought I'd mention, if you find anything about a USB port being disabled, don't worry. I manually disabled it because it's damaged. I don't need it so I'm fine with leaving it as disabled.

Not sure if I have to bump the thread or not, sorry lol, I'm so new to this.

What did you change do , add , or remove three weeks ago ?

Take look at your reliability history and see what clues you can offer for that time period three weeks ago ?

Update: I'm not sure if this is a related issue, but I'm also getting some random full black / full white screens where i can't do anything except reboot my computer. I made sure my NVIDIA Geforce 9200 is updated properly, and my monitor is plugged in correctly. Not sure what's going on.

Here's a screenshot of my Reliability history. I haven't made any changes other than Windows Updates and Driver Updates, and a few Game installations but they were all legitimate.

I can't go back to the original date it started happening as i reset to factory a couple of weeks ago.

-sigh- Another BSOD just happened. I'll post the new BOSD folder with the new Minidump.

and another one just happened....-sigh-. It said "SYSTEM_SERVICE_EXCEPTION". I'm now on my boyfriends laptop typing because it wouldn't boot up and is now going into start up repair. I'm about ready to throw this computer out lol
