BSOD at almost every attempt to boot PC, error 0x00000124

Hello everyone,

I got my PC around 4 years ago and never had any serious issues until now.

A few days ago, I returned to my PC after a few hours idle time, and was surprised to be greeted by a BSOD. I hoped that it would turn out to be a one time thing, but as a matter of fact I can't even boot windows 7 now without getting aforementioned bluescreen or just a random reboot (mostly right before the password input should appear). Booting in safe mode works, but after some time browsing I encountered the BSOD again. After a little bit of safe mode google research, I'm inclined to think that the problem is probably hardware related, maybe some of you guys could shed some light on how dire the situation really is.

Any help / information is highly appreciated. Also please let me know if you need more information from me to diagnose the issue.

Thanks in advance and have a good day!

Aha as soon as i saw 124, hardware popped in my mind.
Anyhow your probably correct : BUGCHECK_STR: 0x124_Genuine Intel =
Stop 0x124 - what it means and what to try
That link provides the most probable solutions to your issue. Anyhow I believe i once had this problem myself on a laptop about 4 years old only mine was AMD. I came to this site, for assistance and was assisted. It encouraged me to learn the ways of BSOD debugging, even though i knew nothing. SO i would like to help you as best as i can!
MY 1st step of advice, is clean out any dust using compressed air or a vacuum cleaning hose(I did it with a vacuum and it worked, but your choice as some say its not safe). Even if there isn't much dust do it anyways it fixed my problem. Second stop overclocking if you have, Then follow other instructions in the link above. As well if the problem is still persisting, you can lower the vcore settings.
Please run the following
Stresstests:
Ram : RAM - Test with Memtest86+
General hardware: Hardware - Stress Test With Prime95 ( (Three pre-set configurations are available: Small FFTs and In-place FFTs, and Blend. Small and In-place modes primarily test the FPU and the caches of the CPU, whereas the Blend mode tests everything, including the memory.)
Graphics: Video Card - Stress Test with Furmark (Do the above Graphics test only with the latest drivers, and then Run it until the temperatures stop increasing; should be less then 10 minutes. If you don't see any crazy glitches or distortion on the screen, The test most likely passed. Take note if the Temperature gets too high, or you see Visual artifact - Wikipedia, the free encyclopedia to stop the test.)
