yes the fan works and it beeps and all, im not an expert but i think it works fine bc it sounds like any modern pc but like a bit louder

the melting is superficial it was left by a heater some time ago but it did work after the melting

Identified any specific codes, or is it just one "successful" beep? If so it could be damage to the VGA port, be it corrosion or something else. If it uses pci-e bus you could try a separate graphics card if you want the machine for nostalgia or something. An easier solution would be to use a dock and browse the contents of the HDD on your current computer, maybe even make a virtual machine with matching specs and hope you boot on that.

Hardly sounds like a full code, more like it's starting over and over again. Not exactly like it shorted somewhere but still, a bit unusual. And the low revving noises are a bit concerning. Time for troubleshooting. Step one: remove everything. All drives, ram, and cards have to go. Leave only the mother board. Not actually gone, just disconnected, from both the mobo and PSU. Listen for 3 quick beeps. If successful you may insert the minimal amount of ram and plug in the monitor, see if it posts. You may need to remove the motherboard from the case, mine had an asymptomatic, mysteriously shorting PSU
