Don't know why, but every time I try to upgrade my own computer, it never works. Symptoms: Power to CPU (fan running), no video output (but fan on Video chip running), no power LED, HDD LED on all the time.

This has happened four times already - three times around Xmas time, and once again tonight.

I've upgraded other computers for friends, and haven't run into any problems. What could I be doing wrong ??????

Current system:
ASUS K7M MB
Athlon 700 Mhz Slot A CPU
512 MB RAM
Toshiba DVD burner
Lite-On 52x24x52 CD burner
80 GB WD HD
40 GB Seagate HD
3 1/2" floppy
300W PSU
Full tower case

Tried to install three SOYO Dragon Lite MBs with 512 MB RAM, and XP 2100+ CPU around Xmas, and an ASUS AU13 MB with 1 GB Kingston RAM and a XP 2200+ CPU tonight.

Also note that the K7M MB only lines up with 6 case screws, and the four MBs I've smoked line up with nine.


HELP !!!!!!!!
