Help me... non stop crashes!

[oOSniperOo]

I wonder if you guys could help me out?

My Myself, my brother and next door neighbour have a network installed purely for gaming purposes. Since (And only since) the network was installed my brothers computer has done nothing but crash... sometimes often during a gaming session and sometimes not. Me and my next door neighbour do not seem to have ANY problems and very very rarely crash and when we do it is just normally to the desktop... his crashes seem to me a mixture of "back to desktop" crashes and full system halts.

All systems were built by me but.... like I said only him with the problem.

I am hoping some/all of you could help me???? Please....

JUST A THOUGHT

Check you brothers computer for excessive heat!! Is it located in a well ventlated area or enclosed. Might need to install additional exhaust fan.
