Yesterday I tried a procedure I've done before with no problem - a RAM upgrade on a friends PC. Usual process, disconnect cables, remove side panel, earth hands on case, remove old RAM stick (256mb) put 2 new ones in, switch on. PC powers up - nothing on the monitor (though if the cable is disconnected it says so on screen "no signal"). Drat, wasn't sure what the RAM was I was putting in (usually I do), so stick the old stick back in, start up, Same nothing on monitor. Have I fried something? Can I try sticking in a spare graphics card I have in an AGP slot to circumvent the built in graphics of what is an oldish e-machibnes Celeron PC? Any adfvice/thoughts welcome.
