Themken: The memory in the graphics card has gone invisible / stopped working. The PC is still usable but any 3D game I tried either does not work or very badly.
I wonder if I should try to heat the (presumably single) memory chip and hope it is just bad connection and the heating will fix it. Not sure it is worth it for so much work on a thirteen years old laptop.
I guess it could also be the BIOS chip gone bad.
Sorry to read that. If you allow me, my 2 cents: I wonder if I should try to heat the (presumably single) memory chip and hope it is just bad connection and the heating will fix it. Not sure it is worth it for so much work on a thirteen years old laptop.

If you are not talking about GPU, I suggest you search for programs that test the video memory, they were limited to 128mb I guess and are rare pieces but exist: I think I found only 2 or 3 and they only work with 10+ years old video cards. Those diags could give you a hint if faulty memory.
Also, some of those benchmark programs (Sandra, PCBench) I think have benchmarks to video stuff that could give you a clue: Faulty video cards won’t finish the test, the PC will hang during the test.
Another easy: After some use, turn off the PC and carefully sense with your clean fingers how is the temp of the chips on the board (the black plastic surfaces), you will really notice if any is hotter than the rest (the magic of using a bare hand vs costly & sophisticated tools)... or if the board is in general hotter: give it more ventilation! :)... and being there, take the time & space opportunity: Give some loving cleaning the board with isopropyl alcohol, don't forget the contacts that fit on the mobo. Expand to some compressed air to the whole case internals maybe? Dust can create resistance, and resistance heat, and heat....
Once everything perfectly dry, re connect making sure contacts fit firmly.
(Not covered: Some video cards had fan, others glued/thermal-paste heat sink instead, others the whole combo. After years, the contact between the chip and the heat sink is loose and the heat dissipation is not the best. If thermal-paste: Enjoy just replacing it. If not: then imagine a proper specific solution & implement)
Good luck and keep alert of weird screen effects, sudden BSOD, strange slowness.
Hope this helps
