mining slowing down hard drive

[blacbe]

i just started using my miner as my regular computer and i have 3 gpus in it. i have cpu affinity set to 1 core and mining uses 25% of my cpu. whenever i unrar something or my hard drive is reading, writing, or copying it's about 5 times slower than it is when i'm not mining. like a 1 gb file would normally take me a minute to unrar but while mining it takes 5 minutes. i'm not sure what this could be. i didn't have this problem in my old computer i had two gpus in while mining.

i'm not sure if it's just the hard drive. i tried uninstalling the cpu and hard drive drivers but it didn't help. i'm using windows 7

Do this. Check your CPU performance and see if have the bug. Try installing 11.6b catalyst drivers or the new 11.9 (not everyone gets rid of the bug with the 11.9) Try that out. Also , if you are downloading the block chain to a client, it will kill your hdd during the download. Flash drives dont suffer from this

I wonder if WinZip is stupidly trying to use the CPU core that the miner's are using.

As an experiment start WinZip give it different CPU affinity and try to zip/unzip.  If performance improves then windows stupidly is assigning winzip to the same "overloaded" core.

You could try and applying these tweaks, blacbe.

If you have a, not so good hard drive, these tweaks will improve your system/hdd speed on Win7.

Not saying it will solve your problem, it might/might not.
