I believe this problem has to do with my newly bought AMD Phenom 9950 X4, 2.6GHz 4MB total L2+L3 Cache that fitsinto the AM2+ socket

When I try to start the computer everything is fine until about ½min or more. After that the computer decides it wants to shut itself down as if somebody had pulled the plug. The time when this happens can differ but it usually don't take that long.

The reason I suspect the CPU to be the problem is because if Ihave time to check the, directly translated from swedish; Device handler, it just says that the CPU's drivers haven't been installed properly.
- CPU= "Mathematic Processor -
The Bios says that the temperature is about 60-62C, which is quite high but nothing that usually shuts my computerdown. Concerning the Bios I suppose I could say that the computer also shuts down while I'm looking at the Bios, sometimes even faster. Same thing when I start the computer in Safe Mode

I'm wondering wether installing the CPU's drivers manually would help but if so I'm unsure how. Perhapsit could be put on a USB-memory stick.

My Specs are:
-Windows 7 Ultimate
-WD 500 Gb
-1Gb ramx3,
-Chieftec 560W
-Sapphire HD3875 512MB
-Asrock K10N750SLI- 110 dB link
-It doesn't say wether this MB is compatible with Win 7 but it worked fine with my former CPU, a Athlon 64 X2.
- Phenom 9950 64 bit X4 (New)
-Zalman CNPS7500-CU LED (New)

With new I mean that I the problems began after I installed them and that the problem supposedly has to do with compatibility,installation or software connected to these.
Summary of situation:
-Computer shts down while starting up after a while no matterif you're in Safe Mode, in the BIOS or at the boot menu. (Never gotten myself together to formate my hard-drive as it's never been any problem. The "Enhetshanterare"= Device Handler, my head wants to translate it into Device Controll(er) but that might very well be wrong, says it can't find any drivers for the CPU or MathematicCPU="Matematikprocessor". Otherwise the computer seems to be working as usual.

I'm pretty sure I forgot to mention something important aswell as put alot of uneccesary information but hopefully there's something useful otherwise just request anything you'd like to know and I'll try to figure it out. Secondly I'm quite sorry for you guys who has to read my english when it comes to the technical terms and I'd like to apologize for that .

Anyway Thanks alot guys

go to the manufacturers website and download the chipset drivers.

[Keywal]

could be that but to be honest it sounds like a hardware issue in that, the chip isn't in correctly.

did you use thermal paste or tape when putting in the new chip?
temp isn't high enough for the machine to automatically shut down but... it may just be sensitive and have a fail safe to shut down at a certain temp

[Georgios]

Thanks for the quick replies Key but honestly you really have to destroy the CPU to get it in the wrong way.

For me I just dropped it into the socket and locked it. Same way as with the Athlon 64 X2 and that one worked without any problems
Now ofcourse it could just be me who can't understand what youreally mean with "chipset" but, concerning the other option that I can think of, that the MB hasn't got everything inserted correctly I'd like to ask what could be inserted the wrong way/not inserted at all that would shut down the computer like this.

About the chipset drivers, would it work to burn/put the installation program on a DVD and boot using that DVD? Never tried and I kind of imagine there's a much better way than what I cancome up with myself

Edit:
Directly from the MB-manual: Support for SocketAM2+/AM2 processors: AMD Phenom FX/Phenom/Athlon 64 FX / Athlon64 X2 Dual Core/Athlon X2 Dual Core/ Athlon64/ Sempron.

Really makes me curious wether this MB canhandle the Phenom 64 X4 9950BE CPU. If not what kind of MB would you guys recommend?

[Georgios]

I suppose I could at that I switched back to my old CPU, the Athlon 64 X2 that had work earlier. Well it did, once. That was on the second attempt to start it after which it wont go past the screen where you can choose f2, f11 etc. I'm quite worried that this has something to do with the motherboard right now and if I somehow have manaed to damage it. Of course me damaging something isn't that uncommon.

The difference from prior to trying the new CPU, and as a matter of fact the new CPU also, is that in both cases it went past the selection screen very quickly which it wont right now. Or well it has done that twice but it usually shuts down right after it goes to the boot menu, which I'm trying to reach to be able to boot using my Win 7 Cd. To make it even more fun the only option I could see at the boot menu was the floppy and no USB DVD, I'm using an external DVD-drive.(or reader whatever it's english name is *sigh*)

Bottom line is my PC is in a pretty sorry shape and my primary concerns is right now what that is wrong and wether I can fix it myself or if I'll have to get a new one from the store.

[Keywal]

This is unfortunate.. could have been anything.

maybe you pushed it onto the board to hard?? its only a guess. at this stage i think someone qualified with some major experience should actually open it up and check for damage...

[Georgios]

Ok I changed my mind about the temperature. When I started it this morning it ran...rather...fine. Fine meaning that it didn't shut down after 5sec.

The important thing I suppose is that after a couple of seconds on the screen where I can choose f2,f11 etc it continues but then tells me "reboot and insert proper boot device". I'm using my old CPU and can accesthe Bios as supposed but now again with fan running at full speed the BIOS shows me atemperature of 91C. Talk about reasons to be frustrated. I did apply thermal paste

I could boot using the DVD I have but problem is it isn't an option at the boot menu and somehow I believe the heat to be the problem

some ideas on there of things you could try..

[Georgios]

Thanks. Disensambled thewhole computer again and checked the socket to see if there was anything wrong but it, and the pins on the CP, seems to be alright. Now I'm having this time of joy all over again as it's shutting down after a very short time not because it's hot...Pfff

Oh well gotta check those things, then I'll see wether a friend of mine knows something about computers that just crashes when I go back to school next week.

Does the system shut down in the bios if you run in it? If it does you know it's a hardware issue. If the only thing you've changed is the processor, then more than likely there's a conflict. Is your power supply adequate for the job? Does your motherboard require an upgraded bios to run the new hardware? Let us know...Jazz

The problem, with the computer shutting down, is still there even after I switched back to my old CPU. The Chieftec should be up for the job as the only thing that differs from my old spec is a new fan, which aint bigger than the last one. Concerning upgrading BIOS I'd love to try that but I do need a computer that doesn't shut down after 1-2 min or shorter.

After a couple of tries where the computer decided to stop at the selection screen before POST, where you have the option of choosing f2,f11 , it once worked again letting me as far as to the point where Win 7 starts loading ^.^. Jokes aside, I'm not sure if it's the harddrive's fault I'm more curious wether the problem could be the motherboard and if it has taken some kind of damage when I tried to run the computer with the new CPU. It did run sure but it didn't find the CPU's drivers and it shut down after a while as I said.

[jazz3000]

Hard to know but I'd check the temps on my cpu as your bios might be set to shut down if the core reaches a certain temp. Is your fan adequate for the cpu and what type of thermal paste are you using to maintain temp controls? Jazz

[Georgios]

The Bios is defenitly set to shut down at a certain temperature as it did happen sometimes in the past, I used the thermal paste Zalman Provided with their Fan.

That's how the fan look like and it's working fine for me from what I can see from the outside.

Ye I believe the temperature was to blame before but right now it shuts down so quickly even after a 1-hour "rest" and there's no heat at the processor or the copper fins. But has any of you guys hear what might lead to a computer shutting down if it's not the heat? I'm pretty sure my Chieftec CFT-560A-12C 560-Watt Power Supply, found the complete name, can handle it.

Computer gets to desktop then these error comes from the programs that start automatically:

The instructions at 0x002070fd referenced memory at 0x000000ff The memory could not be written.

Click ok to terminate the program

CPU/Windows? It worked alright until I clicked my computer to chck the device manager at which point it shut down again.No significant heat a.k.a not the heat I could feel when it shut itself down before these problems started
