Random crashes and system freezes on windows 10 and 7.

I keep suffering system crashes on my PC. It has been a stable build for a number of years and nothing has recently changed in terms of hardware. I've had Windows 7 32 bit on one drive and Windows 10 64 bit on another drive.

In the last few months I have suffered frequent BSOD and crashes on Windows 7 so I did a reinstall of Windows 7 yet I still continued to suffer these crashes. Some of the mini dump files would refer to IRQL not less or equal however it was typically a different answer for each crash each time.

I could I have been playing a game, watching a video or the PC could have just simply been switched on and got to desktop before crashing. Other times the system would run fine for a few days before then returning to crashing. When it crashed it would just instantly restart the PC mainly but other times the image would freeze and I would get a constant buzing sound from the speakers until I reset the PC.

Notably Windows 10 64 bit on my other drive has no problems with crashes at all. It runs like a dream and so I installed Windows 10 32 bit on the other drive. Unfortunately Windows 10 32 bit suffers with the exact same problems that Windows 7 did and crashes frequently by either restarting of its own occurred or freezing and maing the buzzing sound. The unfortunate thing since changing to Windows 10 32 bit is that not a single dump file has been created and there are no critical errors showing in event viewer either.

Any suggestions?

I would download memtest86 and run scans on your ram sticks, 1 stick at a time. Only error count you want is 0, anything higher will explain all the random BSOD as all data in PC has to go through ram, and if its bad, PC will suffer for it.

it makes a bootable USB so can run without windows. Test each stick 8 times

What are specs of the PC?

freezing isn't normal behaviour for software errors, hence reason I asked you to run memtest86. No Dump could mean it wasn't windows or drivers causing error. If PC freezes, it hasn't got time to make a dump file.
