Multiple BSOD in Windows 7

I am getting multiple BSOD on this computer. (It is a client's computer) I have attached a table showing the multiple minidumps. Crashes seem random. I am unsure where to start on this one. The OS was fresh install. Files were moved via microsoft's easy file transfer stuff.I have done a diskcheck and a memory check without any problems.

Here is the configuration:
Windows 7 Pro, fully updated
Gigabyte P55M-UD2 (newest bios)
Intel i3  540
Ati Raedon HD 4500, 1Gb (CCC v. 10.2)
Giel Value 4GB RAM
Sata Running in ide mode
HP Officejet V45

I already posted the minidump contents in a table. This tool just displays it differently. My problem is the "drivers" are windows components. Anyway, here are the results from "whocrashed"

This definitely looks to be a case of borked memory.  I'm assuming with 4GB of RAM you're in a 2x2GB configuration.  In a 2x2GB situation:  Pull one of the chips and run just off one of the 2GBs.  If the same thing happens, pull that chip and install the other back in.  In a single 4GB situation: same as above, replace the chip and see if it still occurs.

If it STILL occurs after that, disconnect all non-essentials (printer, etc), otherwise you may want to look into RMA'ing the board, as it sounds like a faulty controller.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

are definitely a case of faulty/defective RAMs. Are you sure you ran Windows Memory Diagnostics Tool? I had BSOD with these 5 codes before, and WhoCrashed was nowhere in diagnosing these BSOD codes. I'd rather you run Memtest86+ to check your RAM again. This program is more detailed than WMD from Microsoft. You can get a copy here @ http://www.memtest.org/#downiso . Just use IMGBurn to burn and boot from CD/DVD.

If the RAM is okay, try running HDD diagnostics downloaded from the respective vendors. It can be downloaded @ http://www.tacktech.com/display.cfm?ttid=287

I ran Memtest86+ already, but only 1 pass. I am running it again and will let it go for a few hours. I will then run a lower level diagnostic on the hdd as suggested. May play with the ram swap as well. Based on the posts above, if the RAM and HDD don't show problems then it will probably be a motherboard issue?
brandongohwhCommented:
It could be one of many possibilities including drivers, hardware, disk errors, corruption etc. The motherboard may be one of the causes. But of course, tests should be runned first to accurately diagnose the problem.
icsbudapestAuthor Commented:
I let memtest86+ run all night and it is showing 1027 errors in 27 passes. Is there any way to save the error reports in memtest86+? Anything I should look for in particular in the results before shutting down? (I don't have much experience with memtest86+.) If nothing else I'll take a digital photo of the screen.

did you try using another RAM? yours RAM might be bad buy new RAM

there can be one last test for RAM
boot system with Linux live CD and see if it can take you till its desktop or not
brandongohwhCommented:
I haven't heard of any methods to capture the screenshot of Memtest86+, but it is okay to post the screenshot if it isn't so blur. As for the RAM,try testing it 1 at a time. For the faulty RAM, take it out and wipe the gold platings with dry tissues or anything equivalent and try testing it again. Sometimes, it may because the RAM is dirty (physically).
icsbudapestAuthor Commented:
Now I am doing a test of the memory one at a time, using the same slot. Meanwhile here is a screenshot. The errors seem to happen during test 7.

icsbudapestAuthor Commented:
With single stick memtest86+ Ram test, Stick A had 6 clean passes, Stick B (In same slot) had multiple errors in tests 5 and 7. Looks like we have the culprit! I will return the faulty RAM. I will get some new RAM and once things are running, I will come back and confirm that this solved the problem.
