Will a PC even start if the CPU is busted?

Hello,

I was wondering if a PC will even start and go into BIOS if the CPU is busten/fried/broken.

Thanks in advance for your help,

F.

PS: Also, what are some tell tell signs that my CPU got fried?
 
No it will not. (generally)

Usually when a CPU fails it normally goes out completely, though I have occasionally seen ones that are fried to a degree, and operate at lessend frequencies, or don't work with thier cache enabled, lock up constantly even when everything else is working fine and occasionally I've seen ones that just stop being stable at stock speeds. These occurances are rare though. The bulk of the time, when they are out the system won't post.
 
Alright.

The reason that I am asking is because when I installed a new E6400 D2C processor in a compatible mobo it felt a bit... forced. Now I've read different reports that installing these processors requires a bit of force and I was wondering if perhaps I overdid it.

My PC right now starts and goes into post. I can enter the BIOS and change anything I like. THe problem I am having is that as soon as I go into the black screen with the Windows Logo and the progress bar I get an error message saying that Windows XP could not boot up.

I am using practically all new components and my previous old hard drive. My hunch feeling is that the hardware upgrades were so massive and in such a large scale that my Harddrive is not seeing eye to eye with the rest of the now updated PC.

Any thoughts?

PS: The E6400 stock fan is one loud mother. Is this normal?
PPS: In the BIOS, it reports that my CPU temp is a cool 33 degrees Celsius.
 
If I remember correctly, computer will not power up at all if its the mobo, and power comes on/fans start spinning. Nothing onscreen.
 
Two options...

Format and reinstall windows or repair the existing windows installation.

I'd try the latter myself.

yup.. thats what happened to me when I had a P4 chip die from overheating. :D
 
First thing I'd try is a Linux Live CD. If the computer boots that up and runs OK, which I suspect it will, then you've pretty much narrowed it down to a Windows problem and a repair or reinstall is in your future.

This is a good Linux Live CD distro. It's a 50MB download. Burn the iso to a CD and boot your puter with it. Doesn't affect your hard drive in any way, it just loads and starts up linux and a windowing system right from the CD. It's really neat.

And, yes, if the CPU is fried, you won't get anything but some beeping from the motherboard.

I second this suggestion, and I have done this several times with PC's myself.

That and it could narrow things down to a hard drive problem too. I've seen plenty of drives pass diagnostic tests and still need replacement. Though you'll know if repeated OS install attempts fail without any other reason.
 
BTW, if the Linux Live CD doesn't work, I'd probably suspect RAM first (depending on the failure mode.. I'm assuming it fails during startup the way Windows did)

best idea ever!
 
I'm willing to bet it's just windows reacting to the hardware changes. I've had mixed luck switching things like that. sometimes it's ok, and others it's not. If you're posting fine, then it's probably not a major hardware issue.
 
so are you guys saying that a mobo will not post at all if the processor is dead? the reason i ask is because i just hooked a new psu up to my mobo and now i am getting the no video on screen deal.

For my bedroom home theater I have an old dead processor/mobo setup to control lights and fans in the credenza(fading effects, flashing, etc with a 5.25" bay light/fan controller). I think this is a dead processor. Power and spinning fan, nothing else. I put this in what I believe to be a dead mobo, and I get nothing. I never get anything with dead mobos, but power and nothing on the screen with dead processor. Also tried different RAM to be sure.


Not to get off topic, but is there a better way to control the lights and fans in the credenza? I use LED case fans and cold cathodes to make a back glow to the LCD and credenza. Looks good but hate having a PC case back there.

It will simply not load windows if you installed a new motherboard. you need to reinstall the operating system.
 
What is the error that you are getting?

A reinstall should fix it, and if not, I bet memtest86 might help.
