You may experience various erratic behaviour of your system with certain applications.
Renoise is one of the applications that asks the most out of various hardware components:
-Graphics card
-Audio card
-Memory
-Disk drives
-CPU.

There may be a few causes that can be related to serious erratic behaviour of your system.
in 99% of the cases, Renoise is not to blame but it does give you an indication you may have a serious hardware issue somewhere on your system as your system is being requested to perform on it’s maximum capabilities.

On of the cases may be an underpowered CPU data-bus which is usually related to Pentium IV mainboards where the mainboard requires an additional power plug (JPWR2 which is a four pinned connector) from your powersupply in order to power up the bus of the CPU.
You can figure this out by scanning your mainboard for having this extra four pinned power socket near your CPU socket.

If you still have problems you can have other malfunctions at different hardware inside your machine.
Try swapping your memory prints if you have more than one memory Dimm. Sometimes there can be a timing problem on your memory bus because you have different brands of dimms but the same specifications or it may be just a problem of corroded contacts that cause these cosmetic effects (which can be severe). Reseating or swapping may solve this problem.

Another memory related issue I see in the field is: Some mainboards allow the owner to use memory of different speeds and people seem willing to do that because their budget doesn’t reach for a faster memory dimm. It is however not wise to use different speeds in one configuration (combining P C2100 with P C2700 or P C3200 with P C4300 if the mainboard allows them.).
Not only shall the system run on the lowest speed (the weakest link), there is still a risk that this timing problem may cause hangups or BSOD’s anyway, even though, this still may also happen with two dimm’s of the same brand and same specs.
How and why? Because one of the dimms may have been exposed to a / multiple extreme situation(s) such as sufferring from an electrostatic discharge. You can’t see this from the outside, but you will notice it eventually as components will die out slowly after such exposure.
One of the reasons to always use ESD-kits when working with the inner components of your computer.
Yes chances are 94% to 98% that nothing noticably will happen when not using such kits, but remember that once the component is damaged, no matter how perfect it’s behaviour:it will only deteriorate faster and you can’t repair either.

If diagnosis of your audio, memory, harddrive and video card fails (meaning you get a result that everything seems to pass the tests but you don’t feel you can rely on the results) there is also the possibility that you have faulty capicitors on your mainboard which can cause all kinds of nasty side effects which relate to several different hardware components inside your PC, but in fact are not defective themselves.
