Problem with GPU or PSU or whatever.. you tell mee!! HELP asking this question everywhere for weeks..

[berny22]

Ok I just got a new GPU... ATI Radeon HD 4850 Toxic.... it is working fine all the time but when I play a game for a while my screens goes black or in some other colour with white stripes and the it the monitor shows me No Signal on my dvi cable, it goes black and it turn offs(HP 2311x).. I don't think the monitor is the problem..... Then I have to restart my computer... It is not an overheat problem because all the temperatures are fine... CPU 39° - 50° and same for the gpu... only problem with my gpu is that when I looked at the GPU Diode(MemIO) the temp is really high 50-60°on idle and 90-110°on full load... anyway I want to know is my psu strong enough and what is the problem with all of this... This started to happen after I got the GPU but the GPU worked just fine on my cousin's pc.. so here are my specs.. and helpp meee!!

CPU: QuadCore AMD Phenom II X4 Black Edition 965, 3400 MHz (17 x 200)

GPU: SAPPHIRE TOXIC HD 4850 512MB GDDR3 PCI-E
PSU: Corsair Builder Series CX430

I can only guess but in order of likeliness I would say GPU, PSU then motherboard.

It might be the PSU

If you have another Video card, try to replace your 4850 with that and see if the problem persists. If it comes back then it's probably a bad PSU. If it doesn't come back then your 4850 is probably bad and needs RMA'ing.

I think it is the PSU as well... GPU worked fine with my cousin's pc... and my old gpu GTS250 worked fine on my pc.... so I'm suppoused to buy a new PSU!?

I think you might have to get a psu with more watts. maybe a 550 watt or a 600 watt

Would a CX600 be enough...

most likely

Actually now that I checked the power requirements for a 4850, AMD states you need a PSU of atleast 450W. Your CX430 should have been enough, but I guess there is too much power consumption from the whole PC to power the card under load. You should be fine with a CX600, and that would give you some head room if you decide to get a better GPU down the road.

 

[cramved]

Crushice is right

 

[smeezekitty]

The card is still suspect though.

 

[cramved]

The card is still suspect though.

How?
he tested with another card?
