Random crashes, BSODs, bleeps when turning on... Help!

[HexagonalBolts]

Hi,

We bought all the parts for a computer a few months ago. The original PSU was extremely loud so we sent it back for a more reputable one, a corsair, amazingly this blew in the computer (pop noise and some smoke). We sent it back and got a replacement. Ever since then the computer has been plagued by problems:
- Blue screens more than once a week.
- Sometimes the screen will freeze (but the mouse cursor can still be moved, strangely).
- On start up it originally always made a bleeping noise, the noise varied in pattern for the first few months, then became a constant bleep, but has now become more rare. We thought this was probably related to the RAM. we have tried removing one stick and removing and reinserting the RAM but to no avail.
- Other than these problems there are no noticeable problems.

We've become really exasperated by those problems and would very much appreciate some help. How likely is it that we have a faulty motherboard or that it was damaged by the initial PSU problems? I had initially changed the computer's RAM settings to match the specifications of the RAM, is there something I may have missed? There is an option in BIOS to restore it to 'fail-safe' settings, might this help? We have taken it twice to a computer technician but he claims he was unable to find any problems.

run Memtest
how do you mean 'you changed the computers ram settings'? I might be wrong but i thought on an intel board, the bios would just load the XMP profile and the ram would run at it's rated speed with no outside interference.

After the memtest, if it comes back clean, 'fail-safe' yes, it's called clearing the CMOS, Basically select that option, and everything in Bios will be reset. try that and see if the problem persists

Thanks SeraphX, we'll give the memtest a go.

I believe that initially it wasn't set at the right voltage? I just checked again and the DRM voltage is set at 1.5v and it's running at 1600mhz. I don't quite remember as it was a fair while ago now...

1.5V is adequate for most ram, my knowledge on sandybridge memory is beyond rusty, but i think it's the case that it should be run at no more than 1.5v, lower being better obviously, something to do with the cpu's memory controller or something

Ok, my brother has had a computer technician look at the computer. He ran full memory tests on the memory, graphics card and hard/solid state drives and found no errors, he was unable to find a definite problem but he reckons the motherboard might be on the fritz. I've also managed to get some photos of the blue screen crash, sometimes it warns of a 'volmgrx.sys' error and sometimes 'Ntfs.sys' instead, does anyone know what that indicates...?

Both related to the hard drive / file system.

Have you tried re-installing (or repair install) of Windows? I'm wondering if when the PSU when pop it corrupted some OS system files. Might we worth a shot before you replace any hardware.

If not, yeah, I would agree the motherboard is dodgy. Seems like you have an assortment of issues, so the mobo would be my first port of call.
