i recently bought a 8800gt (BFG 8800gt oc) & installed it in my XP machine, consisting of a overclocked C2D 6400, 4 gb corsair ram on a gigabyte GA-965P-DS3 + a good quality quite new 600watt PSU (and im using the forceware 169.21, but the driver i installed when i fitted my card was a different forceware version, im not sure which one tho i later changed it for the current 169.21) the machine had been running faultlessley since i put it together, until now,

i dont know what the hell it is but i keep getting the following symptoms:

machine blackscreens, then quickly changes to BSOD (but the blue screen comes and goes so quickly i dont get chance to read it, like one quater of a second quick) then machine just reboots normally!

it always seems to happen when i first turn machine on, and it has just finished booting into windows, and it goes! then usually again in say 30 mins, then it can not happen again, all session,or until i put a game on, then about 30 mins in, it goes again!

there is no artifacting, or grafix problems!
apart from the problem explained, the card seems to be working perfectly, i have been checking temps, and they are never drastic (for an 8800gt) and it wont be temps because it nearly always goes when i have just booted up into windows XP!

I thought it was PSU, but it can play realy busy bits of games No problem, then just out of the blue it will go again!

also when it reeboots the windows critical fault thingy pops up (asking to send details of problem to microsoft etc) and it has the following details on it:

BCCode : 100000d1 BCP1 : 0000002C BCP2 : 00000002 BCP3 : 00000000
BCP4 : B97D6B8F OSVer : 5_1_2600 SP : 2_0 Product : 256_1

And another time it had this:

BCCode : 4e BCP1 : 00000099 BCP2 : 000000FD BCP3 : 00000000
BCP4 : 00000000 OSVer : 5_1_2600 SP : 2_0 Product : 256_1

also there was a few files about the error that the fault reporting thing was going to send, that i saved just in case they mean anything, one is called Mini122607-01.dmp, one is a text doc. called manifest, and the final one is an XML doc. called sysdata ?

the error reporting thing coming up leads me to (guess) that it is software based problem, (but i dont really know)???

Should i send the card back?
do you think it is a hardware or software fault?
if i send it back can i send it to overclockers? or does it have to go to manufacturer? ive only had it about a week, and it has never been overclocked!
(luckily its got a lifetime guarantee)

help, help, help!!!!!!!!!
cheers
 
ok, the psu is a Tagan one with multiple 12v rails, quite pricey, and nice quality, never had any probs with the psu before, and b4 the 8800gt it was running a 7900gto (similar power consumption)
when i put the GFX card in, i also fitted a 400gb sata HDD, that i used to use in an external drive, (the room i gained from changing from 7900 gto to 8800gt allowed me to fit it in!)
also i fitted 2gb of ram at the same time! the ram that was already in was corsair CMS2-6400 c4, and the newer 2gb was the same, but the older ram was rated at 5,5,5,12 but the new stuff is rated 4,4,4,12 ??? (i dont know if this makes any difference)
the reason i thought it was 8800gt at fault is because i have seen some other posts complaining about same problem!
also it doesnt always shutdown at bootup, but usually within 10 mins it goes, it is very random, and the windows critical fault reporting thing doesnt always come on!
i might try taking ram and hdd out and trying like that for a bit!
luckily BFG has a lifetime warranty, so even if it takes a lifetime to sort i should be OK !!!!???? (and knowing my luck it probably will)
 
just checked, the old 2gb of ram that was in the machine is 6400C5, whereas the newer 2gb is 6400C4 ???
could that be the cause of this problem?
 
FIXED
turns out my system wasnt too keen on having the 6400 C5 (2GB) and the 6400 C4 (2GB) running together. (my stupid fault really i should have double checked the type of memory that was already installed when i got the new corsair 2 gb sticks! for some reason i thought it was corsair XMS2 6400 C4 already in my machine, SILLY.!!!!!!)
anyway ive took the C5 sticks out, and bought another 2GB of C4 to go with the C4 i got in there now!)
thanks everyone for your help
