You are getting a variety of stop codes that can indicate hardware issues. The latest dump file blames Memory_Corruption as the probable cause which usually indicates out of date Drivers, Bad Memory or incorrectly configured Memory Timings.
Run chkdsk /r on your system drive/partition. If chkdsk finds errors it may be worth running the manufacturers diagnostic tool. Links can be found at HD Diagnostic
Download and run CPU-Z. Take screenshots**/snips of the Mainboard tab, Memory tab and all the slot #'s under the SPD tab.
Go to Post Reply, click on the Go Advanced button and attach the screenshots**/snips to your post for all the RAM experts to see by using the paper clip you will find on the top toolbar. Do not zip them up. **If screenshots, please crop.
After Ram settings have been verified:
Run Memtest86+ overnight, after your computer has been off for about an hour or two so it has a cold start. Ideally let it run for at least 7 passes / 6-8 hours. If errors appear before that you can stop that particular test. Note!! Any time Memtest86+ reports errors, it can be either bad RAM or a bad Mobo slot. Test RAM sticks individually. When you find a good one then test it in all slots. Post back with the results.
If Ram and your hard drive check out OK then you may need to run Driver Verifier. Possibly other hardware tests.
I'd suggest that you first backup your stuff 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 Windows 7 Startup Repair feature).
You can make a Startup Repair disk by going to Start >> All Programs >> Maintenance >> Create a System Repair Disc.
To start Driver Verifier:
- GoTo Start and in the Search or a Run... Window type verifier 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 every option EXCEPT for Low Resource Simulation and click Next.
- Select Select driver names from a list and click Next.
- Select all drivers listed that are 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. If this happens as soon as Windows tries to start then try it in Safe Mode. Continue to use your system normally, if you know what causes the crash, do that repeatedly. The objective is to get the system to crash because Driver Verifier is stressing the drivers out and hopefully create a pattern.
On the extremely rare occasion that you can't get into Safe Mode, use System Restore from your installation DVD / Restore Disc to set the system back to the previous restore point that you created.
If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).
To turn off Driver Verifier when finished, Open a Command Prompt or Run... window and type verifier /reset and press Enter/OK. or GoTo Start and in the Search or a Run... Window type verifier. Select Delete existing settings and press "Finish".
