Frequent BSOD 0x000007A error and mini dumps not getting saved

Hi,

I have a Dell Vostro (Core i5) installed with Windows 7 32 bit, MS Office 2010 Professional, MS Security essentials and other softwares. There are two problems I am facing

1. My system crashes frequently (almost daily) and reports 0x000007A error. As instructed I have uploaded the SF folder. Initially I thought it might be due to faulty installation of MS Office, as the crashes would occur when MS Excel file would be load with a heavy pivot or had too many formulas in it. So I reinstalled MS Office, however, to no use in resolving the BSOD prevention

2. To save the crash records in mini dump files, I changed the settings (Start--->Control Panel--->System--->System Properties--->Advanced--->Settings button under 'Startup and Recovery') to save the mini dump file. But this is not working as my computer did crashed a couple of times over the last few days and there are no mini dumps for it.

Please advise.

Suhas

Hi Koolkat77,

Thank you for your response. I have never run my system in safe mode, so not aware of it. Second, I have run the diagnostic tools which come with the Dell system (as the Dell support guys always insist on the result from these tools before commenting for a solution, even for warranty claims) and all the tests show the system to be healthy. I will complete the tests recommended by you and share the results.

Once again thank you for your support.

Suhas

Hi Koolkat77,

Please find attached the RAM test screen shots. As recommended, I run the test twice (1-heated system, 2-cold system) and for minimum of 21 cycles. In both the cases, there was no error reported.

In between, the system did crash 2 or 3 times. But somehow, the crash report didnt get saved.

Please advise on the next steps.

Hi Arc and Yoyo,

On the bios upgrade, is it a simple process? As I am a novice level technician.

On the questions asked by Yoyo, below are my answers

During the past three weeks, was the PC stable? - crashed twice
When you say the system crashed, what happened? - initially it froze and then a blue screen appeared with 0x000007A error code
Did the PC just shut itself down? Yes and then restarted on its own
How much time roughly into the tests did the crashes occur? The first crash after 4 days and second after a week or so
Were you able to turn the PC back on right away? yes. on both and the earlier occasions, I had the following softwares running on my system (I was working on them)
- Google Crome with multiple tabs
- IE9.0 with multiple tabs ~10 tabs
- MS Excel - a heavy file with pivots and formulas
- MS Powerpoint - more than one file with charts and smartarts
- MS Outlook

Initially I thought it might be due to faulty installation of MS Office, so I did reinstalled it, but to no success.

Please advise.

Suhas
