"Usual causes: Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus, Device driver, NTFS corruption, BIOS" http://carrona.org/bsodindx.html#0x00000050
As you can see, this problem can have many causes. Best to start by ruling out potentials.
1) Minidump files are dated 6/9 - 6/18/2012. What was new since just before 6/9/2012? (new hardware, software, malware, or any specific error messages). This may help to narrow down the search.
2) Check hard drive for file corruption by running chkdsk /R
- Use Option one
- Be sure to check both boxes (in Step 8)
- Restart the computer. Check disk will proceed through 5 stages and can take several hours to complete. If errors are found, it should be run again.
3) Test netbook for bad memory module using a bootable USB flash drive:
A bad RAM (Random Access Memory) module can cause unwanted computer behavior such as freezing and BSOD.
- Download Pre-compiled EXE file for USB key (Win XP, Vista, Win 7), unzip file, plug in USB Flash drive, and run "Memtest86+ USB Installer.exe." Set computer to boot from USB drive first.
- Boot the computer with Memtest86+ flash drive.
- The program will auto start. Allow it to run through at least 7 "passes" for minimal confidence; 12-24 hours for moderate-maximum confidence or until it registers any errors.
- The test can be stopped as soon as an error is reported (in red). Press the ESC key to reboot.
- In case of errors, isolate the problem module should you have more than one memory chip, by testing one chip at a time, in the slot closest to the CPU. Take precautions to avoid static electricity when handling sensative electronic components.
- If a memory chip tests bad, then retest that chip in a different memory slot.
- Remember, any errors can mean a bad memory stick or bad memory slot on the motherboard.
4) Make sure that all netbook drivers (especially video driver) are up to date by visiting the Acer site: http://support.acer.com/product/default.aspx?modelId=3658
and selecting the correct operating system.
5) If the above steps do not help, then temporarily uninstall your anti-virus software to to see if the BSODs stop.
As you proceed, let us know.
