I've installed a new motherboard (Biostar M7VIG) with a Athlon XP 2100 cpu. I've also upgraded my power supply from a 150 watt to 400 watt. When I plug the computer in and attempt to boot, I get whirling of fans, a light on the CD Rom but no video or beeping sounds. I'm pretty much over it by now! Any ideas?! Thanks! Carol

try reseat the cpu and make sure its fully seated. if i were you, i would check the jumper and make sure they were correct and if it still doesn't work, then the motherboard might be defective.

also check the ram, are they running at same speed?

your motherboard support SDRAM and DDR ram, never put SDRAM and DDR ram together, they won't work. please advice. here are the species for ur motherboard MOTHERBOARD MODEL: Biostar M7VIG CPU SUPPORT: Socket A AMD Athlon XP , Athlon and Duron Processor FSB: 200/266 MHz CHIPSET: VIA KM266 / VT8233A SYSTEM MEMORY: 2 x 184-pin DDR DIMM 2 x 168-pin SDRAM DIMM Maximum 2.0 GB PC2100 (DDR266) EXPANSIONS SLOTS: 1 AGP 3 PCI bus slots 1 CNR I/O: 1 x Parallel, 1 x Serial 1 x PS/2 Mouse, 1x PS/2 Keyboard 2 x Rear USB 1 x Game Port, 1 x Speak-out, 1 x Line-in, 1 x Mic.-in 1 x Floppy 4 x IDE Hard Disk Devices 2 x Front USB 1 x Front Audio ON BOARD AUDIO: AC'97 2.2 Audio CODEC Onboard ON BOARD VIDEO: S3 Savage 4 Video Integrated ON BOARD IDE: Ultra DMA33/66/100/133 DIMENSIONS: Micro ATX Form Factor 24.4cm X 24.4cm ( W x L )

The Ram I'm using is SDRAM, no DDR with it, 256 PC133. I've taken both out and reseated them just to make sure and still nothing.

Sounds like it's one of five things, In order of what I reckon the problem is: 1) Theres a DIP switch on your motherboard which determines what RAM (SDR/DDR) the CPU/Board is to use and that switch is set to DDR when the DDR dimms are empty. Find this switch and make sure it's set to SDR. 2) The RAM is bad 3) The CPU is dead. 4) The video card isn't seated fully or is faulty itself. 5) Something internally wrong with the motherboard which means RMA'ing it.

I ended up removing the cpu, which I had bought through Ebay and was not as advertised, and taking it to a pc tech who took one look at it and told me it was fried. Literally burn marks on the top. So I was ripped off by a seller. Thanks all for your help! Carol
