Black Screen after A bit of Gaming

pointgiven · Dec 2, 2013

Hi, I've been having this problem for a little while now where after an hour or so of gaming, more specifically Dota 2 on full screen 1080p, my computer's fans will run high for a second, go back to normal and my screen will go black saying "No Signal". To get it back to normal I have to force shut down and restart my computer. More recently, It has been doing it more frequently and has become an issue. I have suspected it to be overheating but I've monitored the CPU temp which never goes above 40, and haven't gotten a temp on my video card but to the touch its always been cool never hot even right after a black screen. I have no idea what the problem could be.
My Specs:
Processor: Pentium(R) Dual Core CPU E5800
Video Card: AMD Radeon 7xxx series GHOST Edition
RAM: 4 GB
PSU: I have two separate PSUs; one for the card alone (which was added after I originally got the computer) and the separate one that came default with the computer which still powers all its original components. The one powering the video card is a Thermaltake, 850 watts.

what video card are you running. an 850w psu should be enough for your pc, there is no reason for a second psu. eliminate it.

Install MSI Afterburner & monitor your gpu temps. With Afterburner, you can change the fan profile and get thefans spinning faster/sooner.

daswilhelm :

actually leave the thermaltake and remove the other one. sounds like a oem system. it probably overheats. either the cpu or gpu

daswilhelm :

plan to update soon anyways so never planned to remove the other PSU. I mentioned the video card above unless you're asking for more specifics.

laviniuc :

thats what i meant, should have said remove the original one.

Lets see... R7700. Yep that's it

daswilhelm · Dec 2, 2013

the 7700 (series) doesnt require much power at all. why are you using two power supply's? if its a 7770, you can get away with a 300w psu. if its a 7750, even less.

Never intended to remove the original that's all. Planned on Stripping it all out and starting from scratch anyways. Getting new components and what not for christmas to build my own using the existing PSU and video card. Please note that I've had this setup for a while now and it ran fine first two or three months.. And only got black screens very scarcely afterwards. Just now started getting bad after a long weekend of not being here... If it will help the problem at hand then I'd have no problem with removing the original PSU and hooking everything up to the Thermaltake

daswilhelm · Dec 2, 2013

thats the first troubleshooting step i would take. while you are in there clean out any dust.

pointgiven · Dec 2, 2013

Alright I'll go for it now. Be back on here in a bit..

daswilhelm · Dec 2, 2013

good luck.

It seems my Thermaltake did not come with an ATX chord that attaches to the motherboard.. Not aware of what that is or if it will be a problem. Any idea?

daswilhelm · Dec 2, 2013

whats the model number of your power supply?

pointgiven · Dec 2, 2013

I believe it to be R33567, But there are a lot of other numbers and asian characters. Try that one.

daswilhelm · Dec 2, 2013

nope wrong number. i dont know why you would be using two power supply's, let alone one psu that isnt atx. remove it and use your original psu.

pointgiven · Dec 2, 2013

Well does the thermaltake support atx? Will it cause problems in the future?

daswilhelm · Dec 2, 2013

does it? i wouldnt know, you havent told me what kind of power supply it is. there must be a model number on the psu sticker.

pointgiven · Dec 2, 2013

I was giving you the model number for the original. The model number for the Tt is SP-850AH3CCB. My apologies if that is what you meant.

daswilhelm · Dec 2, 2013

that thermaltake most certainly has an atx connector.

pointgiven · Dec 2, 2013

I will check again. Just moved recently so could have lost it in the mess.

Q: 4 pin connector into the motherboard?

daswilhelm · Dec 2, 2013

that psu is semi modular, the atx connector should be one of the wires coming right out of the unit, it shouldnt be removable.

pointgiven · Dec 2, 2013

Yes there is a 24 pin connector straight from the psu to the motherboard but coming from the old psu was a small 12 V 4 pin connector. It's labeled ATX on the motherboard. Btw thanks for sticking with me this far. Dont mean to be a bother
