Windows 7: PC Wont Make It To POST

I agree, may be the PSU.

Is the CPU fan itself spinning up?
If not, it may be shutting down if it detects it is not working.


For the time being, I would continue to do as everyone has suggested and leave it with minimal HW untill you can isolate the issue. The less the better.

Tried taking out the battery.. Still the same result.. Would the PC fail to boot due to a hot CPU? I pulled the heatsink off to check the fan, and the CPU is cooking hot

BTW : Identified Processor as Intel Core2 Duo

If the CPU fan itself is faulty, the bios should detect it. It may even give a message about before it shuts down

And yes, it will shut down if the CPU gets to hot.
How soon it does so, depends.

Not sure if this is a cause to your issue, but a suggestion that may be worth taking a look at.

Does the fan spin when you power it up?
Do not start the PC with the HS off!!

Yes, the fan does spin when the pc turns on.

Could this be a dead motherboard issue, seeing as I can't get into the BIOS, and it won't post?

I'm just about at my project deadline. Do you think this is a dead motherboard? If not, what should I tell my friend?

Extena,
Disconnect EVERYTHING. Remove EVERYTHING.

Keep the cover off of the unit until problem is located.

When you took the heat sink off of the CPU, did you then clean the cpu surface and apply heat-conducting paste. If not, do this first!

When I said everything, I didn't mean cpu but I do mean all memory, all cards, all drives, all external keyboards, mice, monitors.

Now when you apply power, what beep code do you hear?
Check that beep code against the documentation for that motherboard.

If you don't even hear a beep, then either the Power Supply Unit is bad or the motherboard is bad.

Thanks for the reply Karlsnooks.. My friend ended up going shopping for a new computer this morning. Thanks for the info however, and I'll keep it in mind in the event that I'm ever in the same situation!

Thanks to everyone who helped, and +rep for all
