Possible CPU overheating/audio and game problems

post #1 of 6
Thread Starter 
Hi, I'm having trouble here and really need help - I built this desktop:

Intel DH55HC board
Core i5-760 not overclocked
2x4 gig DDR 3 RAM
EVGA geforce gtx 560 ti
500W coolermaster PSU
Windows 7 Enterprise x 64

Now, long story short I got it all configured and then fired up Half-Life 2. The game played terribly but looked great, I was getting high framerates but it would stutter and slow down. It's really unplayable that way, so I did a bunch of software troubleshooting and eliminated pretty much any chance that it's a software issue.

In the meantime while I tried to figure that out, I discovered that when I try to play mp3s (only mp3s, not CDs or youtube or anything else) it stutters throughout, and seems also to play slower. Since I mainly want this system to play video games and periodically listen to music, it's unusable doing this. For about 4 days, I tried a lot of fixes - driver stuff, sound buffer settings, etc etc with no success. I even tried putting in an old SB Live! value and found drivers called KX for it, and that didn't stop the problem either.

So I thought maybe it was something thermal (throttling) or a hardware issue - realtemp was showing the cores running around 25-30, mid 40s tops. However, in the BIOS the temperature was much higher - stabilized around 65 Celsius. I've cleaned off and reapplied the arctic silver on the CPU more times than I probably care to think about, and used both the stock intel cooler and Thermaltake 1156 with about the same results. THEN, I looked at the memory and realized I put the sticks in on different color slots! (the same channel). I hated myself for about 5 minutes, then switched them to the blue bays, thinking for sure it would be the obvious fix. But it didn't stop the madness. I'm approaching the deadline to send a lot of the stuff back, so I really need to get this sorted out. Could these problems be heating issues, or would it be shutting down if it was that bad? Is there a chance I damaged the RAM sticks or memory controller by installing them on different color slots? Any other thoughts or ideas are much appreciated.

Your power supply is the bare minimum required so that could be it. Can you please post a detailed build log. Half life 2 is an old game and my pc can play it at like 150 frames per second at max settings (specs are in my sig). You are runing a brand new hardware so something is definitely wrong. If you could post pics that would help a lot too. You can use imageshack.us to do that unless you know of a better way.

Also downlad your mianboards guide and make sure everything looks right and that you followed it. You can get it here:

Also after i reread your post.... I noticed you said the temp was 65 c. I have never gotten my insanely over clocked pentium dual core to show over 30 in the bios. When you are view the temp in the bios it is doing next to nothing so something is defiantly wrong. You might have the cpu heatsink applied wrong.

Hi, thanks for replying. I know that the power supply is probably weak for the long run and that particular model of power supply isn't actually 500 watts but more like 460 or something. The video card uses 170W, and processor 95 so that's 265 right there. But, it's the heat that really bothers me. I've done it so many times and I'm not sure how else I could apply the cooler and compound. I've seen threads where the voltage regulators were in the way of the socket and making it sit wrong also.

What I ended up doing is returning the Intel board and got an EVGA H55 board. I'm hoping it was just some mystical DMA or IRQ or bus thing that the new board will fix, and that it will run cooler. I'll put the processor and heatsink in when it's out of the case so I can see if it's sitting flush on the processor. A new power supply would be nice, but I think it's not the main thing right now.

You're right about the BIOS - that's like the definition of "idle" and the lowest I could get it was around 45 celsius which is still high. I'm thinking if it still runs like this with the new board I'll have no choice but to exchange the processor. Then, if it still acts like this I'll know I have to get someone else to put the heatsink on (long shot) or it's the power or even less likely, some memory thing. I'll give full specs and pictures later, thanks for the advice!

Before you return anything else PLEASE post some pictures of it together but out of the case. And while on that subject, did it come with motherboard stand offs that you are not using. They could be causing a shot with would cause those problems. Those stock intel heatsink are the biggest pain ever to get on and im still not sure if i ever got mine on right. And one last note, a verry detailed parts list would help also, the more info the better/ And the H55 part of the evga board is the chipset not the model number. all motherboards that use that socket use that chipset

I'm posting this from my new build, it plays mp3s and will test games soon. The CPU is running at a decent 35-40 celsius, as I have a constant readout from the awesome temperature update on the Post LED. It must have just been the motherboard, I have more testing to do but that's what it seems. I AM SO PUMPED.
