Thought I would appeal to some of the fellow tech experts about an issue I am currently having.

I am currently in the process of upgrading a family member's computer, more specifically the cpu. The desktop originally had a celeron but it was running a tad slow,so I figured with the current mb, I could upgrade to a pentium dual core. I checked and double checked the motherboard specs and even consulted a tech from the computer shop to make sure I got a compatible processor. I also made sure I updated the bios so it would support the new cpu. However when I installed the new cpu, I got nothing, not even a POST. There is definitely power and I triple checked all the connections. My gut feeling tells me it might be an issue with the power supply (450 watt) or that the motherboard simply does not support the new cpu, but I thought I would get a fresh opinion.

Since Im leaving for Calgary tomorrow afternoon, any help or insight is greatly appreciated.

Try clearing the CMOS first. Always update before upgrade.

Can you post your computer's specs? Motherboard make and model? Celeron and Pentium models? BIOS version?

Also, it's a pain in the ass, but it wouldn't hurt to put the old celeron back in there to see if it still works, on the off chance that you may have killed one of the components during the upgrade.

Yeah MB Specs would not hurt

Any dip switches on the motherboard?
Also did you change the settings in the BIOS to accomodate the new proc?

If it won't even post the first thing that I would look at is that the CPU isn't seated properly. Remove the fan, and remove the CPU and make sure the notches are lined up properly.

2 good things to do; makes it easier knowing which MB it is. Was there any beep codes coming from the MB speaker during POST or some MBs use LEDs to indicate error codes too.

Ill give clearing out the cmos a shot.

As for the specs, Im currently using an Asus p5v800-mx motherboard with onboard sound, video, and ethernet. The cpu im trying to install is a Pentium dual core E5300 2.6 gigahertz model. System has a standard casing with 450 watt power supply.

When I first started having this issue, one of the first things I checked for was to make sure all the connections and the cpu were firmly in place. As for the old cpu, it works fine, so I may just put the old one back for now.

Im also going to try a couple of things on my own and will let you guys know if they work :). Thanks for the suggestions so far.

I found this manufacturer's list of compatible CPUs.
http://www.asus.com/product.aspx?P_ID=DwQbLuB78OdZD3VT&content=specifications#
(Sorry you have to manually click on the last tab)

The E5300 does not appear on the list (although it may not be completely up to date since the motherboard is discontinued).
Does anyone know if the E5300 belongs to the Pentium D family of processors?

Answer my own question - E5300 does NOT belong to the Pentium D family.

So processor is incompatible with the motherboard?

These are the two part numbers for the processor
BX80571E5300
BXC80571E5300
The link to the list of compatible processors, updated Sept. 2009, for the ASUS P5V800 MX Motherboard is below. The E5300 does not show up on the list.

http://www.cpu-upgrade.com/mb-ASUS/P5V800-MX.html

cancowboy2001 is correct. This processor and this Motherboard are not compatible. However the E5300 does belong to the Pentium D Family. http://processorfinder.intel.com/details.aspx?sSpec=SLB9U

The Techs the OP spoke too need to stop handing out advice. JMHO

:confused: Intel classifies the E5300 as belonging to the "Intel Pentium Processor for Desktop" family.
Click to expand...
Pentium D
Produced From 2005 to 2008[1]
Common manufacturer(s) Intel

Max. CPU clock rate 2.66 GHz to 3.73 GHz
FSB speeds 533 MT/s to 1066 MT/s
Min. feature size 90 nm to 65 nm
Instruction set MMX, SSE, SSE2, SSE3, x86-64
Microarchitecture NetBurst
Cores 2 (2x1)
Socket(s) LGA 775

Core name(s) Smithfield, Presler

Yes it is a "Intel Pentium Processor for Desktop", but that is just a type of processor that is not intended for Business Class Workstations or Servers. It is however a dual core Proc, as per the specs, which in turn makes it a Pentium D processor.
"The Pentium D[2] brand refers to two series of desktop dual-core 64-bit x86 processors with the NetBurst microarchitecture manufactured by Intel." The E5300 qualifies
JMHO
No matter what, it still will not work for the Asus Board the OP has.

You sourced it out and came up with the info that the proc was not compatible. I just added all the technical BS based on your find.

Hey dunnochit, did Asus test this processor for this MB yet? Since they have chosen to discontinue the MB, they don't have to test any other new hardwares on this MB including this processor!
Logically, incompatible doesn't mean "not fit". You know what I mean! Maybe in your world, if it's not on the list, it's incompatible! Hahaha! :)

I did not use Asus as my source, but then you would not have an argument if you had read all of the posts. The Proc is not compatible with this board. Fit has nothing to do with anything.The fact that it snaps into the socket simply proves the form factor matches. This in itself, has nothing to do with whether it will work or not. And yes in my world if it is not on the right list, it's incompatible. Plus the NO POST when the Proc is installed might be a clue as well, at least in my world.

Most places will take the return, but require a restocking fee. They might make an exception if someone gave you incorrect information, but they may just say if you're going to do manual installation that it's your own responsibility to make sure the parts you're buying are compatible.

Just a bit of an update:

After discussing it with my family, they decided to just get a new mb and ram, rather than take the cpu back. This time the installation went flawlessly, and their computer is working as intended.

Everything's cool :D
