Some advice please on BSoD

Hi,

My son's PC keeps blue screening after a few hours of play on WoW or SC2. First of all I thought it might be a problem with Windows so I reinstalled. This didn't work so I reinstalled onto another HDD and same problem.

So I started down the line of swapping parts out with my daughters PC. Basically I am left with just the CPU and MB and I am still getting the BSoD

Next I swap the CPU to a Intel E7500 and the problem disappears. He can play all weekend with no problems. Put CPU back in and no more that 4 hours pass before it crashes.

I have contacted the place I purchased the CPU from weeks back (not OCUK) and after a while they asked me to test memory with memtest. Seeing as I have swapped everything over I thought that this was a little pointless but did this anyway. I put the PC back to how it was and ran memtest over and over with no errors.

I have also looked at the crash dump info and each time its different. but the problem is resolved when I replace the CPU.

Spec of PC is

Intel Q8300CPU + Stock HS+Fan. (not overclocked)
Asus P5QL MB
ATI 5770
450W PSU
1 HDD

Am I right in thinking that this is a CPU problem?

Thanks for your advice

John
 
As you have described the events it sounds like it is. But it is more likely to be your PSU.

Reason I say this is because your mates CPU is a dual core and all works.
And your system fails with your quad core.
Quad core has a higher energy requirement.
PSU will work with the dual core.
Dual core lower energy need.
But fail with the quad.
PSU fail.

But this is easy to test. Run your CPU in your mates system. If your CPU fails then all good. you know what the problem is. and start the RMA process.
 
Can you do that test and check and see if the PSU is the problem. Size of PSU does not matter if a rail is delivery fluctuating current.
 
So I have tried another PSU and after 2 days its Blue Screened on me.

The list of crashes is different each time

caused by:
tcpip.sys
rdyboost.sys
dxgmms1.sys
atikmdag.sys
ntkrnlpa.exe
watchdog.sys
USBPORT.sys
usbuchi.sys

So I guess this could be a faulty motherboard???
 
Those crashes indicate unreliable hardware - overclocking, wrong voltage, bad memory, faulty voltage regulation on motherboard/PSU. They'd also indicate a CPU that couldn't run at stock. From what you've said it seems to be the only thing left. In most cases like that it's memory, so running memtest is usually the fastest way to nail the problem down. CPUs going faulty aren't so common.
 
Have you tried the cpu in another machine? Also what codes are the BSOD's, would be something like:
00000000x000124 etc...
This can give indications of the cause...
 
Could you show screen of hwmonitor? Temps etc. run prime to simulate gaming.

Was the CPU new when purchased?

Possibly RMA to Intel direct

hi, looked at the link. the bsod code 0000x7e is hardware related, probably the bios or a parameter within it...
Has the CPU been overclocked? and what sorta temps is it running at? as per the previous post, some HW_monitor temps during a prime95 small_fft run would be good.

Possible fixes:
1. Go to the bios and reset to defaults (thus resetting your cpu settings to stock).
2. Try updating the bios...
 
Hi.

Temps running prime are all about 60deg to 65deg

bios has been reset and also updated. would it be possible to downgrade the bios on a motherboard?

not tried the CPU in another pc yet

Thanks again

Flash outside of windows, yes. I still use a boot floppy but a USB drive and a bios utility would suffice I would think.
 
how many sticks of memory are you running? some boards undervolt when running 4 sticks across all the slots. For example my old DFI 975xg board needed 2.2v across 4x2.1v dimms to stop similar random blue screens.
 
I am running 4 sticks (4x1gb). I have tried with with 2 as well.

installed Vista and still get the same problem. going to down grade the bios as I think I may have updated the bios before xmas about when it started
