well, I thought I figured out the problem with my video card I bought (see my first post 'old MB and new video card - need help/advice'). Stupid me didn't look at all the sys requirement and didn't have enough watts flowing to kick the card into gear. So I bought a new Power Supply, a PowerUp 400W Duel 80mm fan. I bought it from globalcomputer.com, and the description said it was compatable with AMD and P4 systems, ATX compliant, and it's over the 300W minimum I need for my video card. So when the PS gets here, I put it in, hook everything backup correctly and push the button to fire up the system. Nothing!! And this is w/o the new video card in, just with all the old stuff. I recheck the **** wires, everything is hooked right. Double check the selector switch is set for 115V, everything looks good. Push the button again and NOTHING!. So I swap out the new PS and put in the old one, everything works fine again, boots up fine, no problem. So I'm wondering if there is some compatability issue with the PS and my system. My system: 1.2Ghz Athlon T-Bird CPU Microstar VIA KT133 AMD Socket A MS-6389 MB supports up to 1.4Ghz CPU 384MB 133SDRAM ATI Rage Fury Pro 32MB Vid card (old, I know:)) on-board MB sound Lite-On LTR-24102B CDRW Std Floppy 20GB Maxtor HD 5400RPM no extra case fans, a modem and a LAN card all being powered by 200W PS Is there some reason a new PS compatable with AMD and ATX shouldn't work? Thanks, Brian
