BFG 8800GTS OC 640

[1284]

Upgraded from 7600GS 512MB with which everything was fine.

Bought BFG 8800GTS 640MB OC new and installed into M2N4-SLI motherboard with Thermaltake 650W PSU so should be no problems (..???)

Followed the manual uninstalling all previous video drivers. Powered off and inserted graphics card and connected up....powered on.

No signal to screen for a few seconds followed by 1 long beep and 3 short beeps. Have diagnosed this as 'Video adapter failure - Bad video adapter or memory' from here http://www.amptron.com/html/bios.beepcodes.html
However it does not turn itself off.

Have I been given a faulty graphics card, is it incompatible with my motherboard, is it going to take ages to sort out, when can i play games?

All products are from Novatech

Try resetting the bios through the jumper sometimes that can help, is the fan spinning on the gfx? And have you plugged the power cable into the gfx card?

[1284]

pci-e power is connected, gfx spins up seems like its fine but then no signal to screen and those beeps

resetting the bios?gonna have to get mobo manual out.

never reset bios vefore, any riskyness??

[1284]

also, my old 7600gs is working fine. problem only occurs with new 8800 gts connected up

[Jonny2Bad]

No none just make sure you read up properly on what u have to do! I had this prob b4 and it sorted it out no problem!!

[1284]

so you don't think it is gfx fault? just incorrect bios configuration?

it cant be motherboard hardware that is almost brand new too

cheers for your help

[Jonny2Bad]

Well it could be but i would try this 1st just to make sure!! No problem!!

[1284]

i see you have the same card from BFG. what card did you upgrade from did you have any issues...?

[Jonny2Bad]

A 7900gts512mb and no its a very good card copes with everything ive chucked it!! What is your cpu and ram like?

[1284]

AMD x2 2.2g, 1gig decent quality ram

this cpu but socket AM2 http://www.novatech.co.uk/novatech/specpage.html?AMD-X242O

have updated bios (M2N4-SLI) and fixed nothing.

i also booted with no gfx card installed using the onboard one....it does 1long, 3 short beeps again but it happens quicker than when 8800 in is in there. this tells me something could be up with the (BRAND NEW FROM NOVATECH) motherboard. or somehow the computer will ONLY boot with the old 7600 installed and/or some simple settings i haven't found need changing...

HELP

[Jonny2Bad]

Did you reset the cmos?

[Jonny2Bad]

It's more likely a setting in the bios set to something different that wont allow it to post with the new gfx card!!

[1284]

im afraid of doing that, i've been building computers, mostly mine, together for years have never come across this so possibly a faulty card - im no good at diagnosing broken bits.

what will it do? i read on maybe this forum some guy had sort of the same problem, reset cmos and it messed everything up for him.

[1284]

btw i've searched everywhere for motherboard manual and cant find it!!!

[Jonny2Bad]

Go to the website and download the manual then!!

[1284]

my mates got an 8800gts too im going over there to see if it works in his machine...

[Jonny2Bad]

I take it you couldnt find the manual online then?

[1284]

found it, reset cmos, tried everything now. hasn't worked in all computers ive put it in so going back to novatech tmoro

[Jonny2Bad]

Oh dear, well at least you can say you've tried everything buddy!!

[1284]

yep. they're getting a kicking if they dont replace it :D

[1284]

out of curiosity what does this mean if you got a 7900?
