Windows 7: PC is randomly freezing

PC is randomly freezing

So it all started to happen few days ago. My pc started to randomly freeze and after freeze, i got windows has recovered from crash message. Under details it said reason for crash was bsod with code 124. First thing i thought is that the reason is some kind of hardware issue. So i ran memtest, everything was fine. Then i ran prime95 but prime95 worked fine and pc didn't froze. I noticed that pc doesn't freeze in safe mode, so i thought it must be a software issue, but verifier and sfc scan gave no results. Today, it started to freeze in safe mode too. Also, my external hdd and usb sometimes don't get recognized. And, at last, it sometimes takes a restart or two to even run the pc properly(monitor doesn't turn on, nothing is going on, only fans are spinnin). So, what is it? Is it PSU issue? Or maybe cpu issue? How to even determine what is it?

EDIT: Attached two minidumps from today's crashes.

If you are overclocking anything, reset everything to defaults. Go into bios and set optimized defaults. Set your ram timings, frequency and voltage to manufacturer's specs, set the boot order save and exit. 0X124 is a general hardware fault but is not very specific. If you have temp monitoring programs keep a watch on the CPU temp and GPU temps. If you don't have programs, you can use Core Temp for the CPU and MSI Afterburner for your GPU. Afterburner is an overclocking software for the Gpu, but it has good monitoring features. You said you ran memtest, how long did you run it? It needs to be run 1 stick at a time in each slot for 8 full passes. Each pass has 10 tests and each pass tests something different. It will take several hours to run 8 passes, best to run overnight. Also run Furmark, but keep close watch on GPU temps and shut it down if they get too high. Video Card - Stress Test with Furmark. Let us know how everything goes.

If you continue having problems, read and follow this Blue Screen of Death (BSOD) Posting Instructions and start a thread in http://www.sevenforums.com/bsod-help-support/ Putting the file resulting from the test above in your first post. You should also go to C:/Windows/minidump copy that folder and paste it on your desktop (you'll have to provide admin permissions) right click the file on your desktop, select send to and click compressed zip folder. Upload that along with the Seven Forums diagnostic report zip file.

EDIT: I have requested this post be moved to the BSOD help forum, linked to above.

so, i tried to do memtest again, and it got stuck at 51%. Yes, memtest froze, time wasn't moving or anything, i couldn't use hotkeys, only thing that was happening is that the + was still blinking. So yea, i don't think this is a ram issue.

Don't worry, can you please follow the instructions, so we can narrow down the possible cause.

Kingofthehill, What brand PSU do you have? With your graphics card, AMD recommends a 400Watt PSU. You have listed in your specs, a 430W PSU. That puts it right on the border line. Depending on the manufacturer, many PSU's really won't put out their rated values and if they do, will only do it for a short time. They will also degrade after some time. If you have a friend who has another PSU, I would try that to either determine the PSU as the problem or rule it out as the problem. I would certainly try to borrow one rather than spend money on something you don't know for sure is the issue.

Memtest runs out of ram, it has nothing to do with the OS. If you froze while doing the memtest, it does not necessarily rule out ram as the issue. But, it does for the most part, indicate a hardware issue.

We can see that the module has become corrupted for some reason, I highly suspect hardware.

I managed to find this driver within the raw stack:

Code:

The first parameter or argument has the value of 0x0, which is a Machine Check Exception, which means the CPU has detected a hardware problem and the address points to a processor error because the CPU has found one, so it could be a different form of hardware which is causing the issue.

In such a situation, it is best to use these steps:All the hardware seeming to be running stable and tests reporting no errors, could mean a bad motherboard.

anyway, today, after a couple of freezes, it worked fine for like 3-4 hours, then it froze, and since then i can't turn it on. Fans are spinning, keyboard seems to work too, but monitor doesn't turn on and nothing seems to happen.
