hmm, sounds like your processor may be over heating. what is the tempature of it during hiload? what does your error log say? start > control panel > administrative tools > event viewer.

is there alot of dust in your heat sink / cpu fan? or in the box at all?

Hi, my events viewer has several errors with MSPAC and application errors as the source. My CPU is always at about 30-40 degrees (C). Umm..as for the dust, there is a bit in there, do you think that could be the trouble?

Event viewer errors:

The description for Event ID ( 316 ) in Source ( MSPAC ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: The event log file is corrupt..

that was the last error i had and my computer just did the crashing while playing FSX. so this error may have somthing to do with it, otherwise im not sure.

Your Forceware driver version and mainboard model would be important informations. You also didn't mention if your graphics card is an AGP or PCI-E type.

Beyond all driver and hardware related issues that might be the reason for your troubles, if you have an AGP mainboard (I guess):

A common hint on sporadic freezes is to turn off 'fastwrites' in the BIOS, especially with Geforce 6+7 series cards. I just had a computer with a GF7600 that needed both 'fastwrites' and 'write combining' turned off to quit freezing in - FS9.1 and others... disabling each item separately didn't help at all, both together solved all stability issues.
(Doesn't cost any performance either!)

hi, im pretty noob when it comes to this side of things, so bear with me. Im on AGP 8x (6600GT), how owuld I go about turning off fastwrites, is searched in my startup menu but couldnt find it. Really appreciate the help, cheers. Oh yeah, my MB is a Gigabyte 848P, as for my forceware drivers..Im beat.

The proper place to disable FW (and try disabling WC, too!) is your mainboard BIOS (press DEL while booting). It can be found amongst the chipset features, most likely at the same place where memory timings are set. ("Advanced" page on some BIOSses) The "Write Combining" feature can probably be set at the same page - in my BIOS this option is called "Video Memory Cache Mode" and it should be set to "UC" (uncached).

If you are unsure about something, please ask...

hey thanks, I'll give that a shot when i wake up! cheers

nope, I checked everywhere (Advanced BIOS, CMOS etc) but just can't find it! any suggestions?? I just rebuilt my PC and it has a fresh install of XP, i thought this may have solved the problem but nope.

That a freshly installed Win doesn't help indicates again that hardware is involved.

What's the make/model of your mainboard? I've read already about boards that don't have an option to turn off fastwrites. Welcome to the extremely user-unfriendly world of graphics cards vs. chipsets..
But sometimes these settings are well hidden only.

You can try "Coolbits 2" to unlock the hidden pages in your Forceware driver control panel (download somewhere on Guru3D.com/ google for "Coolbits"). AFAIR there are "AGP settings" and "Troubleshooting" menus after you ran Coolbits, where you can tweak some things. Unfortunately the old control panel is gone with Forceware 91.47 and so are these menu pages. I didn't mention this before because disabling FW there is a) not the best place and b) doesn't work for some boards (checkbox becomes ticked again after restart).

Another thing to check on sporadic freezes are the chipset drivers. Get sure they are installed and the latest available.

Depending on age of and chipset on your motherboard, there also is a chance that this particular mainboard model doesn't run stable with AGP8x. This could be solved by the flashing the latest mainboard BIOS available, but sometimes there isn't any newer BIOS. If all fails, try reducing the AGP rate to 4x. This helped some people, too.

Keep in touch...

cool thanks, I'll give all of those things a try. If all else fails I may get a new graphics card..maybe that will solve the problem...anyway cheers!
