Description of problem

I've been getting reoccurring BSODS for the past couple of weeks almost every time the PC is booted up. It will enter windows, then either get a BSOD after about 2-3 minutes or freeze up. This will happen once or twice, and afterwards the PC will go on working for hours on end normally. Even though it is ancient, it sill browses the web, plays games etc without fault, even after the BSODS have started to appear. I haven't encountered any which i could strictly attribute to running a specific application which might cause strain on the hardware.

The BSODS are very varied - cache manager, kmode exception not handled, bad pool header, system service exception, bad pool caller, unexpected kernel mode trap.

It's been going on for a couple of weeks with varying frequency. I'd get one or two for a week straight, then none four days in a row, then a couple per day again. All of the descriptions I've read about these BSODS suggest that the culprit might be a device driver that's acting up, but I haven't managed to find out what that might be.

I've uploaded a rar of the minidump folder with dump files from June 2nd to today. here's the link:

Cause/Steps to recreate the issue

It happens at random, always when I start the PC and boot into windows. Safe mode doesn't seem to be affected, but since it sometimes doesn't crash straight away when i go into windows normally, I can't be 100% sure.

What I've tried so far to resolve the issue

I ran memtest on the memory and everything was fine

I ran chkdsk /r. It found two small bad sectors, but it didn't fix the problem

I wanted to do a system restore, but had no points prior to when this started happening.

I've installed bluescreenviewer to see what the BSODS were about, and each time it says that ntoskrnl.exe is at fault, but that's obviously too vague.
