Frame rate drops and generally bad gameplay experience.

Hi,


The problem: Huge inconsistent stuttering during games - Diablo 3 / Skyrim [Stuttering / delayed inventory, images won't load straight away, up to 5 second delay] / Bioshock Infinite.

Interestingly, I can sometimes boot the computer and games will run perfectly, however when I reboot the stuttering has returned.

For quite some time i've been having extreme difficulties with my HP h9-1330ea [ http://h10025.www1.hp.com/ewfrf/wc/document?cc=uk&lc=en&dlc=en&docname=c03542305 ] Desktop computer. The machine came shipped with a Radeon 7770 card which I had extreme stuttering with. Stupidly, instead of sending the computer back I was convinced it was the GPU and so I purchased a EVGA Nvidia 660ti but still the same problems occured.

I think it might be worth mentioning that when I first put the card in the machine it wasn't getting recognised, eventually I figured out that secure boot / legacy support in the BIOS was creating the problem.

Now, i'm no professional but my gut instinct tells me that it's the intergrated graphics card [HD 4000]. Last night I thought I had figured it out, I went into the BIOS, enabled intergrated graphics, plugged my monitor into the onboard, went into device manager and disabled the HD 4000 device as I cannot see the card in the list if I have disabled onboard graphics.

I phoned HP and they asked me to try everything I had already tried 10x over, re-installing Windows, un-installing / re-installing Nvidia drivers ETC. I'm pretty sure this is something to do with the HD 4000.

I'm running on Windows 8 with an intel i7 3770.

I've had the computer put in for a benchmarking test and it passed with flying colours so I can rule out overheating etc.

I really hope someone can help me, this is driving me crazy to the point of returning the machine :(



Thanks in advance!

If you have a video card installed, the cpu's graphics are automatically disabled.

What do you mean you had the computer "put in for a benchmarking test"??? What does "passed with flying colors mean".

Does it even have a cpu fan?

Is the power supply powerful enough to support a 660ti?

Putting in a new video card probably voided your warranty so returning the machine is not an option.

Have you checked to see what your cpu usage is when this stuttering occurs? I'd bet the machine is so full of bloatware that it's probalby running 100%.

Thanks for the reply, sorry for my bad use of words, i'm not that clued up when it comes to computers but unfortunately i've had to teach myself since purchasing the machine.

About the warranty, i've managed to speak to HP and tell them about changing the graphics card and luckily for me they have no problem with me sending it back to PC world for repair, however I don't really want to do this if the problem is something pretty simple [which it probably is]. I'm also really hesistant sending it back to PC world as i've found the people i've spoke to to be pretty clueless and unhelpful.

When I say I put my computer in for a benchmark test, I mean I sent it to a local repair company for a diagnostics test, they tested the hardware / temperatures etc. I've actually had a look on my GPU / CPU temps, the CPU wasn't going over 48 and the GPU was around maybe 60 from what I remember.

Inside the case is a 600W PSU, 1 fan blowing towards the motherboard and one fan on the gpu. My CPU usage is usually quite low, i've never known it to be high.

Thanks for your time!

I would use driversweeper and remove all your intel and amd gaphic drivers, programs like catalyst control center etc.

Boot up into Windows, do not let it install any drivers on it's own, and install the newest driver for the card.
