I recently upgraded my graphics card from an onboard nvidia Geforce 6100 to a separate nvidia quadro FX1500. The system runs on an AMD dual core 3800 processor with 1meg of ram AND WINDOWS XP. The system used to crash occasionally, but now has trouble with large programs like Solidworks and crashes (complete shutdown) midway through a Norton scan. Can anyone help?

Try the ideas in this post:

Hi Jephree,

Thanks for the ideas. I'm not actually getting the BSOD but a complete shutdown (and no restart). I have looked at the event log against the specific error message and found this: Event ID 7026
The following boot-start or system-start driver(s) failed to load:
IKFileSec

This seems to preceed each shutdown. ??

Do you have XP SP2?

A total power shutdown is almost always a hardware problem.

Perhaps the power supply? How many Watts is it?

Are you sure the motherboard is compatible with your CPU and GPU?

Have you ever flashed the BIOS?

As to software get the latest Windows Updates and I'd suggest removing Norton.

IKFileSec (File Security Driver) - c:\windows\system32\drivers\ikfilesec.sys

I'm 99% sure I have XP SP2 but not sure how to check this.

The power supply is 400 watts, but I expect the nvidia quadro grahics card is absorbing quite a lot of power.

This has all got worse because I have been trying to correct the system to operate Solidworks which is a huge program.

So far I have fitted a new DVD drive, new hard disk 160GB, and new graphics card (as above).

Before this, I occasionally got the BSOD, but this has changed to complete shutdown at the same point in every Norton Scan.

Motherboard is Abit NF-95 with AMD dual core 3800 processor (should be compatible). I have not flashed the bios, not sure how to do this.

Don't really want to uninstall Norton unless it is a last resort as I have already used the three reinstalls so I would have to purchase this again. However, if this really seems to be the problem, I would be very happy to see the back of Norton - all trouble!!

Right click My Computer then click Properties.

Or go to start > run winver

You can get a PSU tester to see if the unit itself is functioning properly.

Perhaps it is not enough power. You can try this calculator:

CPU heat could be another factor here. Most boards have an automatic shutdown if the CPU reaches a critical temperature. Try Core Temp and monitor the temp as you run your high end stuff: http://www.alcpu.com/CoreTemp/

My point/suggestion was to remove it forever. Norton is trouble.

Many thanks for this Jephree,

I do have XP sp2. I checked the psu calculator you suggested, and it came up with a psu of 240 watts, so 400 should be fine.

I have also used the temperature indicator whilst running the Norton scan and found that it slowly climbed before shutting down at 120 deg C (normal operation for everthing else seemed to be about 55-60 deg C). I checked the bios and found that the shutdown setting was 75 deg C, so I don't know what is going on there.

I will investigate better cooling anyway.

regards

Well you can be pretty certain that that is the cause of your problem:

The temperature.

Over 70c is burn out potential.

Check the CPU fan. Perhaps clean and lubricate it.

You can also remove the heatsink and clean and reapply new thermal compound.

You can also consider upgrading the cooling system.

If this problem only happens with Norton then that is just another reason to leave it in the past.
