Q: power button has 3 blinling lights

Power Mac G5, power button has 3 blinking lights every 4 seconds, has all new 8 gigs of ram and Radeon x800xt video card. While running a Tech Tool scan on 8-24 as surface scan was at end of scan my screen went dark and the computer started speeding up with a whirring sound like fans running at top speed and getting faster. I powered it down and now nothing but the blinking lights. What is wrong? Mother board? Video card? Ram? Hard drive or the OS?

PowerMac, Mac OS X (10.5)
