Monitor loses signal while gaming; keyboard and mouse randomly die together

Hello,

I've had a series of problems with my computer lately.

First of all, sometimes while playing games with high graphics, the monitor will lose signal and there seems nothing I can do to fix it besides restart. Strangely enough, after dusting the computer out and pulling out and putting in the RAM, I haven't had this problem anymore, but I am worried it will come back, and I wonder what the cause of the signal loss was.

Also, the keyboard and mouse sometimes both die on me, no matter what I am doing on the computer. The monitor will still work after this happens.

Also, I've just noticed that my computer says I only have 6GB ram, when in fact I have 8GB installed. Not sure if that's related.

Any ideas on the cause of these problems, and if they are related?

My computer is about 3 years old, a Digital Storm computer,
Intel Core i7 CPU @ 2.67GHz
8GB RAM (but says only 6GB)
GeForce FTX 275 card
Windows Vista SP2
750W power supply
3 fans

Thank you for your help.
