SHut down issue with 9800gt

post #1 of 7
Thread Starter 
hi guyz.. i am having trouble wiht my gfx card i have a 9800gt which i've been using for weeks, but yesterday i encountered problem my pc is shuts off when gfx card is pluged in after 10 15 mintues but when i take it out pc runs without any problem.. my gpu temps are around 60C so i cant see any overheating issues because i am getting these temps since i have bought and using it and it was working all fine

My take is the PSU is at fault. A 9800GT doesn't consume a lot, but if the rig shuts down after a several minutes only when the GPU is connected there are two options:
*the 9800GT is faulty
*the PSU can barely supply the amount of power needed for the 9800GT, it overheats and shuts down.
To check this:
* grab a powerful fan, as big as you can find, open the side-panel and direct it towards the PSU (this is to minimise the risk of PSU failure while testing)
* start with the 9800GT and note the voltage levels in the PSU (+12V, +3.3V and +5V) with a soft called Speedfan
* start a Furmark instance and continue monitoring the voltages, if they drop by more than 10% below the reference values, then the PSU is at fault

Post back after you've tested this or if you have any questions.

This. Only thing to add is that software voltage monitoring is dead inaccurate, even more so then normal. Grab your-self a multimeter.

very well could be the psu, what are the components in your pc? Powersupplys can become unstable with age or just on the fly also trying what dragosmp has suggested will help quite a bit to help narrow down the issue

+12v = 11.77v
3.3v = 3.15v
vcore = 3v
avcc = 3.18 v
vcore = 1.34v
well these are result after few seconds of testing

Did you get those readings from a multimeter or from software?
