cant boot computer!

[raygunpk]

my old computer wont boot into bios.

i bought a 6600gt for my old computer, then realized performance was bottlenecked so got a whole new computer.

now i also took out the ram and my hard drive from old computer to put it in my new computer, but then put those items back.
i had my new 6600gt in there but have since took it out and put back my old fx5200

the computer specs:
P4 1.8ghz
512mb ram
geforce fx5200
cd drive
cdrw drive
60gb hard drive
and a generic power supply that came with the case
and the motherboard is msi 6457 ultra i believe

basically when it starts, there is one beep, then the cd, cdrw and the hdd led's just keep blinking, forever.

and also, my monitor goes black, instead of having the box that says "this monitor is working correctly, please check video cables etc" when u have your monitor on but not your computer

i have tried reseting the jumpers, taking out the batteries, unplugging/replugging everything back in

please help!

Seems like your monitor connector is loose some something like that. Is your video card very old? Try this; remove your video card and use eraser (yes, eraser) to clean the video card connector and boot your system again. Of course, make sure all power connectors are connected correctly. Also, have you tried to clean your cmos memory?

Boilerplate-01:
. Common causes of failure to boot (no video, no beeps) assuming PSU isn't totally dead:
1- RAM, CPU and/or AGP video card not seated properly, a bent pin or corrosion.
2- Drive data cable on upside down or only on half the pins or shifted a pin or two (usually Floppy or Zip drives).
3- CMOS needs to be cleared (AC power must usually be disconnected or . attempts to clear CMOS may fail) Unless your mobo does not use a power-off CMOS clear - check your mobo manual for specific info.
4- On some new mobos there is a CPU protection feature (esp. on Asus/Asrock Athlon/Socket A mobos) that will not allow the system to start if there is no fan (or a fan without a working speed sensor wire) connected to the fan power connector on the mobo (specifically marked "CPU Fan"). If you tried to start your machine without a fan properly connected, you have to attach a proper and working fan and clear the CMOS before it will boot.
