Hi guys,
recently i upgraded my cpu. I had a pentium dual T2390 to C2D T5800.
Well, my problem is that my laptop needs to boot twice before i get the welcome screen.
To make that clear...When i switch on my laptop before grub loads(cause i have dual boot with linux) a red flashing image pops out for milliseconds.
After i press to boot with windows 7 it just freezes on the welcome screen,after 1 minute a bsod comes out and says about igdkmd32.sys error and reboots itself instantly.Then,after the restart, no red flashing images and windows boot succesful-no bsod, normal temperatures
Well, i have to do this everytime for a succesful boot.This is also happening with linux so i don't think it's windows or generally software problem.
Also noticed something strange. With my T2390 my ram timings were 4-4-4-12(266MHz) and now with the T5800 are 5-5-5-15(333MHz).Is this has to do anything with my problem?
Sorry for my english mistakes :D

Did you check that your motherboard is compatible with the C2D? If so did you check that your BIOS is at the correct revision for the C2D? The memory timings are probably related to the differing FSB speeds between the two CPU's. I would double check the memory just to be sure it supports running at those speeds/timings.
Get your facts first, then you can distort them as you please.

Hi

BIOS errors usually have a red font or a red background color which would fit with Baltboy's suggestions.

A possible cause is if the onboard video and the CPU are confused about who gets what piece of RAM then you could get the error with igdkmd32.sys then after a warm reboot they choose different parts of RAM that don't conflict with each other. If that is the case and nothing else works, you might try popping in a video card and disabling the onboard video.

If you are already using a video card with onboard video disabled or non-existent then I am waaaaaay of base :)

Well, about the compatibility BIOS recognize the new cpu.Beside that i can boot normally the second time so i think it is compatible with my mobo.
Now about the revision i didn't catch that.I also run a memtest and no problems found.
Indeed i have on-board video card-Intel GMA X3100.
I found a guy that had the same problem and solved it by downgrade his ram.He moved from a pc2-5300 to pc2-4200. I have one module of pc2-6400.Replaced my ram with
two modules of pc2-5300 but no luck...
Well it's not bothering me a lot to boot twice but the problem is why.Maybe i'll put back the T2390-i didn't see much of improvement after all.
I may sound like a noob but can i really get rid of my x3100 and put a real video card. Because i think i heard that from NeverSayDie. Or i misunderstood...
Thanks for the replies btw

Hi

Your English is very good. Tell me if you do not understand something that I say.

Here is what I think might be happening. It is only a guess :)

The new CPU and the onboard video have a conflict in RAM that is resolved on the second boot.

Changing the RAM might fix it sometimes but not always.

If you have an extra video card then put it in the computer and plug the monitor into the video card
then go into the BIOS and disable the onboard video
then completely shut the computer down
boot the computer (using the video card with the onboard video disabled) and see if it works.
If it does not fix it then enable the onboard video again.
If it does work, use the video card and keep the onboard video disabled.

But as far as i know my mobo doesn't have any slots to place the 'other' video card- you mean dedicated,right?. It's an OEM /prebuild HP 308A. But maybe i'm just wrong.
How do i check this? I mean if i'm able to place a video card.

Is it a laptop?

If it is then that is my mistake. I thought it was a desktop computer. I don't know how to resolve a memory conflict between the CPU and the video in a laptop.

Maybe a BIOS upgrade but I am always afraid to mess with the BIOS unless I absolutely have to. Especially on laptops.

EDIT: I see that you mentioned laptop memory parts so I assumed incorrectly. Sorry for the confusion.

Yes it's a laptop.Anyway if anything comes up i'll tell you.But i think i'll go back with the T2390.
As i said didn't see much of improvement with the T5800

Thanks
