I have a relatively ancient 775 MB (gigabyte p45t-es3g) that was being powered by dual core e5700. Slower than molasses. I decided on upgrading the cpu and purchased a core 2 quad 9650 which is compatible with the MB.
I have had various issues and in the process purchased a new PSU (corsair 500cm i think), and new CPU cooler (coolermaster hyper 212 evo), and even replaced the HD.

When I installed the new CPu a few months ago, initially there were problems getting the system to work but everything was ok for the past 1-2 months.

Problems have now re-developed where the computer will shut itself down, stalls when starting, gets stuck at the MB screen.

I have tried another friends 775 CPU (specs unknown) and the same issues. I even have gotten the BSOD with messages about questions if new hardware has been installed.

Last night, I went back to the original CPU and all is fine.

Suggestions as to the problem/resolution.?

I have checked and the only BIOS update is a beta version. A friend suggested reinstalling my win 7 home premium but not sure if this is the way to go.


thanks

ps.. I have posted a variant of this on another website. I hope there is no issues posting it here as well.

It may simply be a dying mobo. I hope the Q9650 was super cheap at least.

I think its time you consider to move to a more modern platform.

Yeah I have thought about the mb issue. Current MB is n/a and finding a 775 ddr3 MB that is not microATX is not easy.

I guess I could always pick up a microATX case.

Spent about $85 on the CPU so I am open to suggestions.

An ATX case will accommodate a micro-ATX mobo. Just FYI.

If you see a DDR3 mobo, for 775, suggest you grab it.

Otherwise, if you are in the US of A, consider a G3258 combo from Newegg, or an AMD FM2+ quad-core APU combo from Microcenter.

What ram are you using? The FSB of the E5700 was 800mhz, whereas the Q9650 is 1333mhz. Maybe you need better ram with the Q9650?

There is a guy selling motherboard LGA775 on ebay (new) based on my country....You might want to try your luck there. I am getting one for 2 persons with dead mobos.

Yes, micro-ATX should fit fine in an ATX case. That shouldn't be a problem.

Get your stability issues lined out, then install a good SSD and don't look back.
It will leave that HD in the dust.

That's odd, as micro-ATX and ATX mounting holes are a sub-set of each other. The mounting holes are standard.

What case do you have that it wouldn't fit into?

not sure what case I have but when I look at the pics of the two mb's, the location for where the screws are placed is different.

The standoffs that the current motherboard (if ATX) is connected to, may differ from the ones that the micro-ATX board may use, but you just need to remove the standoffs and move them to the appropriate holes. Every ATX case that I've ever owned or seen, has holes drilled for my micro-ATX and ATX holes. You just put in the standoffs as appropriate.

Thanks very much and good to know. I will see if they can be moved. I am still a bit confused as to why my MB works with the older processor but crashes when a faster processor that is compatible with the MB is used.

Could be a multitude of reasons.
Most likely two, are:
1) VRMs / power-delivery of board can't handle the added power-draw
2) BIOS support, including microcode updates for the new CPU.

Less likely:
3) New CPU is damaged / defective.

just an update.

I installed the new MB with the newer CPU and...same issue..gets to the windows loading screen and then perpetually reboots asking me to start normally (and same cycle) or restore windows. Even with this option, it restarts.

also was able to place the standoffs so microatx would fit my current case. thanks virtualLarry.

Did you set your SATA controller mode correctly, for the new board, as compared to your existing Windows' installation? If installed with AHCI mode, then it must be set to AHCI mode in BIOS. If installed with IDE mode, must be set to IDE mode in BIOS. If installed with RAID mode, must be set to RAID mode in BIOS, and also, the RAID controller chipset must be compatible. (Intel's newer RAID-capable chipsets are backwards compatible.)

Didnt make any adjustments just started up. Pretty sure it was IDE mode. I do see that for the new mb and prior, that gigabyte website indicates there is an mb chipset driver that can be downloaded. Not sure if an update or the original though as it appears to be the same version for both mb's.

I will also place the original CPU in this mb without changes and see what happens
