Ok heres my problem, maybe someone has a clue why my computer hates me. My computer is doing 2 things and I cant imagine how to fix it
1.) it just shuts down sometimes when doing something involving gaming. I figured it must be a power issue even though I have a decent power supply. Anyhow then I finally checked the event logs and see that it says the video card over heated and thats why it shut down. Heres the issue with that though. When I run the FF XIV benchmark it shuts down at the exact same point every time and says the video card overheated... That just dont make sense to me, I can turn the computer right back on and it will do the first 5 mins of the benchmark with no problem again and then boom at that certain spot it over heats and shuts down. Is there any further testing I can do somehow? The computer is cooled well I thought (specs of computer listed at bottom of this post).
2.) Every now and then the screen goes black and all lights on the computer (meaning the HD access light and the neons in and outside the case) all go very dim and blink, and they will all just continuously blink and the reset and power buttons do no respond on the computer at all, I have to turn off the power directly with the power supply switch or unplug it from the wall, and then it boots right back up no problem (Nothing listed in the event logs what so ever).
Power Supply = OCZ GameXStream OCZ600GXSSLI 600W ATX12V SLI Certified CrossFire Ready Active PFC Power Supply
CPU = Intel Core 2 Duo E8500 Wolfdale 3.16GHz LGA 775 65W Dual-Core Processor BX80570E8500
GPU = SAPPHIRE 100245L Radeon HD 4850 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card
Download and run furmark, see what temp the GPU gets up to. Furmark puts an unrealistic load on the GPU so it should hit a higher temp than it was in the games so if its overheating you will see the temp it gets to right before it shuts down. If its at or above 100C thats a problem.
I ran Furmark and overheated pretty quickly... was over 100C withing a minute and hit 120 at around 2.5 mins and the computer shut itself down as soon as it hit 120c. Any suggestions? all the fans are working, the only fan not working is my cpu's fan, waiting for a replacement on that, but the cpu fan wouldnt effect my video card would it? the cpu not having any heating issues (besides the benchmarks today I don't really do anything cpu or gpu intensive atm since theres no intensive games out atm that I like, I've just been playing League of Legends which gives me no problems)
Thats one thing I know nothing about is cooling... I just looked in there the cpu fan is definetly not functioning. So I'm gonna order a new cpu fan... The old one I had was (ARCTIC COOLING Freezer 7 Pro Rev.2 92mm Fluid Dynamic CPU Cooler) link to it: http://www.newegg.com/Product/Product.aspx?Item=N82E168.... If I remember correctly we had a real hard time fitting it in, anyone have a suggestion for a good cooler that maybe is same size or even better smaller? Also what kind of fan should I buy for the back of my case? heres a link to my case http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Last but not least, also do I need to buy paste for replacing the cpu cooler/fan? If so what do you suggest? Thanks
Your problem is the system is circa 2008. it's not a bad system it just needs the thermal paste re newing. It's not a hard job, there are plenty of youtube vids showing how to do it. you might be better off replacing the whole CPU cooler. a single 92mm fan is going to have a hard time keeping your CPU cool. As for the random shut downs I would suspect it is the power supply starting to fail. i only say this because my OCZ 600w modxtreme died about two years ago. It could probably be your system shutting down to overheating. The cheapest fix would be to replace the thermal compound on the graphics card along with any thermal strips and buy a new CPU cooler. They dont cost much more than a decent fan. You'll get another 6 years out of it.
