Hello,
Could someone tell me the cause of this strange green screen? Capture with mobile phone:

I take this new symptom to ask for help: it is a PC that suddenly locks up, whether there is a program running or not, even when doing nothing, it freezes;
it is equipped with an Athlon 64 3GHz, an MSI K9N6 motherboard, 2GB of RAM, integrated graphics on the motherboard, a 500GB hard drive, all running on XP.
I tested the RAM with memtest86+, it seems fine, the CPU temperature is 35°C, I formatted the hard drive completely. Nothing helps. However, I haven't tested the power supply...

We were able to find the solution to the problem with a friend:
it is a failure related to two (out of four) capacitors on the motherboard, which were damaged due to their proximity to the processor + heatsink + fan.
Over time, the heating caused by this has destroyed them (bulging capacitors at the top), a classic issue in modern designs.
The faulty capacitors are struggling to power the processor; the system continues to run, with the capacitors from the other stages of the processor's power supply taking over temporarily, and it eventually leads to random system crashes.
Repair possibility: it is necessary to "break" the damaged capacitors on the motherboard itself, the idea being to remove the contents of the capacitors, leaving only the pins for mounting, and to solder new capacitors onto the pins of the old capacitors (careful, inside, the pins of the capacitors have an aluminum sleeve, so to solder with tin, one must look for an anchoring point elsewhere on the pins).
It is dangerous to remove all the capacitors, given that there are several layers of circuits on the motherboard; use the soldering iron quickly.
The manipulation was performed on my board and has been working perfectly for 24 hours straight.
Hoping this tip will be useful, and thanks to the feedback from the members.

so we need to mark this discussion as resolved.
Congratulations Biquet82 and good luck!
Hoping your PC continues to work properly!
