|My guess is that you're not reporting the error message correctly. It's probably something like ""IDE channel 1 - no 80 conductor cable installed"|
The IDE cable has nothing to do with your restarting problem but it is hurting the overall performance of your system. Earlier IDE cables had 40 wires & were used for ATA33 drives. Later versions have 80 wires (40 original wires + 40 ground wires) & are used for ATA66, ATA100, ATA133 drives. Both versions use the same 40-pin plugs. If a newer model IDE drive is connected to an old 40-wire IDE cable, it will still work, but it will only run at ATA33 speed. As a result, your drives will perform much slower than they're capable of running. More than likely you have a newer drive connected using an older cable which is why you're seeing that message.
This is pretty basic stuff. I would think someone with the name thecompuguy would know all about it?
Other than that, you didn't list your system specs, anything about the video card or which game(s) you're having problems with. It could be your system is overheating, could be the power supply is overloaded, could be a driver problem or software error, etc. And you probably still have XP configured to automatically restart when there's a problem rather than display a blue screen error message. The 1st thing you should do is turn that sh!t off:
