Both are possibilities and there may be an underlying issue for both, is the CPU fan connected to the header on the MB, when the PC is running are all fans running correctly, have you checked the case for stray screws or bared wires that could cause a short!I cleaned the heat sink because it seems like an overheating issue, to no avail. I'm thinking either overheating or PSU was DOA. Any thoughts??
Are you using an add on video card?

Did you remove the heatsink to clean it and if so did you clean both the HS and CPU correctly and apply a fresh amount of TIM?

If your present CPU fan is working correctly then no, if however you have room in your case for another fan and an available header or power supply then add an additional fan.Would you suggest I pick up a new fan/HS just in case?
Ok, below is an example of the type of TIM kit available from all good PC suppliers;I'll apply the TIM and let you know, thanks

We will come back to the DVD drive point when you have tried the above.

Try removing all of the Ram, do you get any error beeps?
We will come back to the DVD drive point when you have tried the above.
Error beeps were one short then one long
By no means a conclusive test of the Ram and slots but the error beeps may suggest they are ok.
You may be correct about the PSU being faulty, you also mentioned odd behavior from the DVD and this may also be attributed to the PSU, leave one stick of Ram in slot one, disconnect any/all optical and HDDs from the MB and PSU and then power up the machine, the machine will not boot up for obvious reasons but does it remain on or still shut down?
