Hi There, I am really hoping someone can help me with my computer. I has been working fine up until very recently when I have been getting occaisional spikes of really high latency that freeze the machine up for several seconds. I use this computer to make music so latency is obviously not ideal! I have followed the steps in the tutorial and have a dpc_interrupt file (and a dpc.txt file) however don't really know how to interpret them. I would really appreciate it if any help / advice was available! Thanks in advace!
