Solved BSOD after taking in PC to repair shop

[serpentracer]

I tested my memory again and it shows no problems...this is getting bad.

I don't understand how it could fail Memtest then pass.

trust me when I say this, it can and it does.

for example I had a compaq laptop that I bought memory for, the manufacture said it works in my laptop but guess what...I was getting the BSOD at random. windows had all kinds of crash reports on all kinds of different things. nothing ever really pointed to a memory problem.

but as soon as I put the stock memory back in it never crashed again.

I tried some old memory (2gb) and my pc still crashed..

At this point i'm thinking of just going back to the repair shop and tell them to take another look.

If the problem isn't with the memory, I'd expect that the motherboard is faulty. While PSU issues can also cause errors in Memtest86, the motherboard is much more likely seeing as the PSU has already been replaced.

 

[Beast52702]

Im going to side with Mr. King on this one. That ram is rated at 1.5 V, if the voltage increase did not eliminate the bsod, and your psu has been replaced(your current psu could almost run 2 of your systems), then it must be something else.

I am not an expert on minidump analyzing so I cannot clearly tell you what it is from that(others can). But I have had situations where I tried everything, for over a month, and it ended up being the mother board. Unfortunately the MoBo is hard to test directly.

Have you been checking your temperatures?
Use Core Temp , to check the CPU temps when at idle, under load and/or testing.
Let us know the minimum and maximum temps you get.

Also, here are the voltages:

CPU = 0.8000V
CPU/NB = 0.8000V
CPU VDDA = 2.50V
DRAM = 1.50V

Are your RAM cards installed in the first two slots, counting from the CPU, slots A1 and B1?

Go to your BIOS, to the CPU/NB voltage to 'Manual' and 1.250v.
Try to simulate the crash scenario, play a game etc.

Let us know if you get another crash, there will likely be a couple of voltage increases. You want to find the lowest voltages that your system will run stable on, this will keep your system running cooler.

Your memory controller is integrated in the CPU, this might need a voltage bump.

Go to your BIOS and change the CPU/NB voltage to 'Manual' and 1.250v.


It is quite common for memtest86+ to show no errors and then on a subsequent test show many error, this is just a fact of electronics, anytime memtest86+ shows errors it means the motherboard slots or RAM is bad, or the settings need adjusting.

If you try adjusting the RAM setting and you still get BSoDs, from the info in this thread I would suspect the motherboard.

Let us know your progress.

I took my PC to the repair shop a week ago and I got an email saying they couldn't find a problem!!!!!

I'm <name>, I'm the technician looking at your computer. I am emailing in regards to the computer you have here at <PC repair place> for service. i have completed testing and i was unable to find any issue with the system. all hardware diagnostics come back good. I am able to boot and run in windows without any issues.

it is possible that the issue is caused by a device that is being connected such as an external hard drive, iPod or any other USB device. it could also be caused by a power issue, like dirty power (spikes and drops in voltage) from a wall socket or faulty surge protector.

if you have any questions or concerns feel free to reply to this email, call us at <number> or come talk to us in store.

Thank you,

I am going bananas here!

What exactly do you have plugged into the PC normally?

 

[win7clutz]

After reading this thread I’d proceed in the following order based on cost:

• Purchase 2Gig of inexpensive, but reputable ram; crucial, corsair, gskill or whatever your MB manufacturer recommends. Test again with memtest and then run box for testing BSOD. If the problem is gone you have a solution, if not, you have little invested and now have future testing parts.
• Replace PS. Do have a friend or someone that you can borrow one from for testing?
• If the problem still exist, Good Bye motherboard... Replace.

I realize that none of these are attractive options, but Dave and Greg have taken you through all the reasonable options.
Good luck with it…

 

[Ferny84]

What exactly do you have plugged into the PC normally?

Just my monitor(DVI), Mouse (USB), Keyboard (PS/2) and ethernet cable.

I tried it at another workstation in the house and it still crashed.

 

[Ferny84]

I noticed that whenever my PC is connected to the internet I get a BSOD, but when I disconnect the ethernet cable it's ok...

Is it possible for an internet connection to cause BSOD?

 

[Corazon]

If the Ethernet driver is bad, definitely. If you already installed the latest version, reverting to an earlier one might help.

 

[Ferny84]

I mean a network connection, not the network adapter.

It seemed to have worked fine at the pc repair place, but when connected here it crashes.

 

[Ferny84]

So I took my video card out and plugged my monitor into my motherboard, using the integrated Ati 3200 gpu.

The PC worked fine all day yesterday and most of today until I put in an old 9800 gt video card into the system.

It crashed so i'm guessing it isn't the video card that is the problem but the PCI-E slot or power supply?

Where should I go from here?

 

[Ferny84]

Installed a new power supply (Coolermaster 500w), played a few minutes of World of Warcraft and it crashed.

What should I do now?

 

[gregrocker]

Have you clean reinstalled since the problem started to eliminate the OS as possible cause?

If not read over these steps to get a Perfect Reinstall to ask back any questions.

 

[Ferny84]

Yes of course I did.

 

[Ferny84]

Been using my integrated gpu for a few days now...still crashed a few times but not as much as before.

As soon as I reinstalled my PCI-E video card, the problems keep coming back.

Crashed as soon as Windows started, then it said something about checksum not being the same.

I'm just going to go ahead and buy a new motherboard.

Can someone recommend one that's similar to mine under $100?

I'm buying from ncix.com.

 

[Ferny84]

So I was going through my BIOS settings and it said that my onboard graphics were "enabled".

I disabled the onboard graphics and when my system is about to log into Windows 7, the screen is black, can't see anything at all.

Is my motherboard borked?

 

[gregrocker]

Go back into BIOS setup to renable onboard graphics.

See if there is a setting in that area which could affect the graphics card favorably. What is the exact problem when you install it?

The screen glitches out like this and then shows a BSOD:

Doesn't matter which PCI-E video card I install.

Then my crashes a few time trying to log into Windows and then it shows "BOOTMGR is CORRUPT CHECKSUM DOES NOT EQUAL" something similar to that.
