For reference here are my system specs:

  • Cooler Master Sniper Scout tower
  • Intel Core 2 Quad Processor Q6600
  • Intel G33 Motherboard
  • 6GB DDR2 RAM
  • Radeon HD 4870 GPU
  • 1TB SATA Drive 7200 RPM
  • OCZ ZT Series 650W PSU
  • Windows Vista 64-bit Home Premium

I'm having an issue where at certain times my display starts to become corrupt, with artifacts appearing. This might happen while playing a game, but it can also happen without using any CPU or GPU intensive applications running. I then see the error message from Windows which says Too many 16-bit programs are running. Then the display becomes completely corrupt and I have to shut my PC down. I wasn't even aware that I was running any 16-bit programs, I'm honestly stuck if anyone can help me out here.

Update 1, I've run a:
Virus Scan
Spybot scan
Furmark Test
Windows memory test
Video card memory test

...and all of them have come back with no problems.

Update 2:
When my PC is idle there are about 55 processes running and 6 icons on the right-hand side of the Windows taskbar, and the CPU is at 1-4%

Also when idle the system's GPU and CPU are approximately 45oC and all other measurements hover around 25-35oC. When under load, all temperatures stay basically the same except the GPU which goes up to about 60oC.

And yes all of the power connections are installed correctly.

You seem to be running a 64 bit operating system, please note that such operating systems can't even run 16 bit programs. For more detail, see this KB article. So, that error makes no sense at all. It would be interesting to get an idea of where that error is coming from; any other details about that message box (or event log) should help you find a explanation online why that message box is appearing, please update your question with these details or ask a new question.

As for the graphical corruption, you have mentioned that you just installed new RAM. So, running memtest to figure out whether the RAM is stable should be the first thing to do. If you have upgraded from 2 GB to 4 GB and thus have two sticks in total, it might be easy to try booting with one of the sticks and later booting with only the other stick in order to test both apart and figure out which of the two sticks is unstable.

There must be something (either software or actual hardware) that's corrupting your computer after a certain non-deterministic event, as this kind is out-of-place as I stated in the first paragraph. You can find more things to try in my last comment below.

In Windows Vista 64-bit this message is evidently bogus, as 16-bit programs cannot run on 64-bit. Microsoft (or another product) is apparently issuing the wrong message for some unknown error-condition.

I would suggest the following :

  1. Search the Event Log for a more detailed error message (if one exists)
  2. Use an Administrator login (if not already the case)
  3. Temporarily disable UAC as a test
  4. See if the problem happens in Safe Mode boot

This is an often reported bug that exists due to an incompatibility between certain security products and this update KB2442962 for Windows, which causes consent.exe to not show up. As a result, this calls a procedure to report you with an error for that situation, but it appears that they have not updated that error for 64-bit editions of Windows. At least not in Vista...

To resolve this, there are multiple solutions possible:

  • Disable UAC.

  • Uninstall update KB2442962.

    MS10-100: Vulnerability in Consent User Interface could allow elevation of privilege.

  • Do a system restore to a point before update KB2442962.

  • Reinstall your computer and make sure you hide the KB2442962 update.

  • Attempt to figure out what security software is incompatible with KB2442962.

I replaced my graphics card and the problem has completely resolved. There must have been some short or damage to the actual hardware itself.
