Bsod
 
numerous times in the last 24 hours ive recieved a BSOD
"MACHINE_CHECK_EXCEPTION"
microsoft states it could be anything from a damaged CPU cach, to a "bus" malfunction ect .. caused by virtually piece any hardware(lots of help then, thanks microsoft)

this has (so far) only happened when
im downloading to my Seagate Barracuda 7200.10 250 GB HDD
at the same sime i ether am
encoding a movie (i can encode but not download at same time)
or defragmenting the above HDD (again whilst downloading)
no crashes undergeneral use inc downloading

it seems do be whilst the hdd is under sustained heavy use, also no problem with playing games (UT2004)

NB. while encoding with my overclocked cpu (AMD64 3000 to 2.21GHz) the screen froze, no mouse movement ect, once i undid the overclock i now get the BSOD mentioned above,

no problems before got the new HDD, in guessing its a HDD problem however the drivers are latest, and motherboard bios latest.

was wondering, are my assumptions correct?

also, if i install a firewall i always get BSOD, mcafee and zonealarm are the ones ive tried.. a known error? of so any help (i was running firewall after the 1st BSOD last night, but uninstalling yeiled no results :( )
thanks for any advise.

Firstly, don't blame Microsoft. The fault lies not with them. I don't exactly like 'soft, but bashing them at every oppurtunity gets on my nerves.
Secondly, the above is asking for trouble. Encoding a movie is tough work for both cpu and hdd, and if your trying to multi-task at the same time with something else just as intensive it really doesn't surprise me you get problems. You really should not multi-task while defragmenting either....lol.
I would check your temps, run memtest to check it's not a memory problem and defrag WITHOUT doing anyhting else until it's finished. At all. Even MSN.
Good luck.

righto,
it just crashed while web browsing...
i shall run memory test (i forgot to mention i upgraded it recently (last 3 months)
also, prehaps my meaning regarding microsoft wasnt clear, no bashing mate, pretty childish tbh, i was stating id looked myself for the answer (google didnt help either, error caused ranging from a faulty network hard, to conflicting sata drivers), frustrated that id found nothing, the sentence regarding microsoft is explained.

Something I suggest for all errors of this nature is the following:

1. Download but do NOT install the latest drivers for ALL of your hardware

2. Uninstall all the drivers using Driver cleaner (avaliable in the files section) from safemode

3. reboot and install all the latest drivers.

Also if you could post all your hardware it could help.

These errors are usually from 1 of 3 different things
1. bad / incorrect drivers or new drivers installed over old ones
2. poor PSU for the hardware
3. hardware failure.

Now the last is a rarity, unless you bought either rubbish hardware, or have overclocked the life out of it, and a AMD 3000+ at 2.21 and running RAM at 1:1 is not overclocking the life out of it.

I agree with noob. Could absolutly be a PSU issue. You are pushing it to the limit and the PSU can't keep the volts up.

grimwig 7th November, 2006 02:59 AM

true, but surly it would crash when playing games?? when my 6800NU is under load?
ive a crappy Qtek psu, 650 watts, but i was able to run 3 harddrives with no issues, (im down to 1 now)... i suspect its my sata drivers, ram is nunning at 201mhz once overclocked, (setting the dividers, as cheap ram) single channel 786mb.
seatools reports no disk errors,
ill try the driver swap tomorrow,

but, memtest, it passed the first tests (19 mins) but turned the pc just turned itsself of atfer about half an hour... im guessing that counts as a fail,

it blue screans not so often, i managed a defrag today, also did a fresh install of windows, no blue screan till after everthing was installed (inc programs and drivers) about once every 5 hours if just web browsing, msn, using word ect.

Could you check your PSU voltages with a DMM?
Also check the 12V amperages on your PSU.

Check with only 1 stick of RAM at a time, to see if either of those are bad.

Also, do you have temp monitoring software? or if not, run your computer for at least 10min (if you can) under load, take the side off and check the temp of the heatsink. If its not warm - hot (probably not burning) to touch you will need to re seat the heatsink with some as5.

Sounds like it is either a RAM or PSU problem - if you could post full machine specs that would be a help.

Also I advise most definately getting a new PSU, of that component most of all you get what you pay for. if you have a 3000+, 3HDD, 1x 6800NU, DVD, and several case fans, look towards something like the silverstone ST40EF (its cheap, reliable, and very stable), Antec TPII 400W+. You will be wanting about 25A+ on a single rail, or 14A on 2 12V rails.

If you are reinstalling XP, insure you install at least SP1 BEFORE you install drivers for the SATA drives, and USB 2.

*******


the hs fan isnt spinning!!

2 secs while i turn pc off, and ensure its plugged in

grimwig 7th November, 2006 12:11 PM

right, plugged it back in

the hs fan literally sounded like a jet for about 2 mins once the pc had pc,
slowly quieted down, and aidia32 reports the cpu temp at 56 degrees, 5 mins after pc boot up, now at 10 mins after it reports it at 40 degrees, falls to 39 as writing.

before I plugged the fan in, the plastic fan part was warm, but the metal hs underneath was burning hot

hopefully thats my problem solved... no long term effects on decoding and defragging on a passively cooled overclocked amd64... heh :eek:

this could have been the case (no fan) for anytime up to about 6 weeks ago,

Samuknow 7th November, 2006 12:29 PM

THat would do it.

No fan will cause a nice rise in temps...

Love an easy fix

aghastpumpkin 7th November, 2006 02:05 PM

I would advise you get yourself a new cooler! Added stability plus lower temps.

noob 8th November, 2006 01:29 AM

Nice to see an inexpensive, easy fix.

grimwig 8th November, 2006 11:28 PM

thanks for your help guys!
