My kids related a problem on the "kids computer", eMachine T2040 running XP. They related the computer CPU seemed to get very hot and got a funny, burning smell. Oh well, let's keep using it and see what happens. The power abruptly shut off and then they brought this to my attention. :mad:

I pulled out the power supply and found a fragged cooling fan and glue like substance oozing from one of the components. I bought a new powersupply and everything appeared to come back to life. Except the built in sound card and CD Rom now longer work. I rechecked the cord connections for data and power and they seem fine. The device manager shows yellow exclamation points next to sound card and CD rom drivers. Uninstalling them and re-installing them kills some time but has no resolution.

Question: could the high temp and sudden shutdown adversely affected and damaged the BIOS chip (where I presume the driver info is stored?)

The driver info is stored on the hard drive though.
You could check on the BIOS to make sure there is nothing disabling the devices, as the power supply failure could have caused problems.

You have to consider that the power supply failure could have actually damaged the devices or the motherboard though, as a prime cause.

What's the best way to interrogate the BIOS to see if it is functioning correctly?
