System consists: Ellite K7A motherboard (6 month old) AMD 1.4 T/Bird (1 year old) 256 DDR (1 year old) Radeon 7500 (new) Generic soundcard (1 year old) Generic 56K modem card (1 year old) Seagate baracuda 60G HD (1 year old) Generic floppy drive Liton DVD Drive (6 month old) Zalman copper CPU Flower Running XP Pro & full works Suite My problem stated approx 1 month ago when turing on the PC. I was unable to get any picture on the screen despite the HD appearing to kick into action. Numerous attempts and light tapping on case would eventually obtain a result. First thought were faulty MX2 Graphics Card, so bought new Radeon which I always intended for scaling anyway. Insalled card & drivers also replaced ribon HD cable for shielded round one in hope to aleviate any problem. I still have the same startup problem. I have checked all the connections (internal & external) the case side is off & the flower fan is running at max, so everying is nice and cool. I have re-insalled XP on my C drive and drivers for all cards, re checked cables but no luck. Once I get a picture (numerous resets) it runs fine, the other problem is that the system of running @ 1050 if I update CMOS to 1400 it just wont run at all. Anyone got any ideas ?
