[URGENT] PC trouble(monitor not turning on) UPDATE : PLZ HELP Urgent I did what u told with the jumper , Monitor is not turning on now . Fans run , even ethernet lights blink , but monitor does not get any signal . the green led is on , i tried putting in 2 sticks of the ddr400 512 MB RAM , there were beeps . Next i put DDR333 512 MB and 256 MB sticks , there is no beeps , but monitor does not turn on . I even tried a different monitor on DVI connection , still didn't work . UPDATE , i tried with a different vid card working in another pc . Radeon 9200 . i tried the elimination process , the DDR400 RAM sticks were giving 1 long beep and 2 short beeps . DDR333 RAM sticks were not giving any beeps . Tried them one by one. but the bios would still not show up. I did put the jumper to normal operation after clearing. I Appreciate everyone's help . Thx a lot guys . My PC : 420 W PSU P4 Northwood 2.8 Ghz 1 GB DDR400 , 512 MB and 256 MB DDR333 RAM sticks ASUS P4C800-E Deluxe Mobo . THe PC would overclock easily earlier with ASUS AI Booster . Yesterday i tried to overclock my RAM with memset . Somehow the timings got screwed . THe PC would reset after restarting . So i uninstalled Memset and set all options to default in BIOS . But now when i try to overclock the PC resets or the monitor loses while processor fans keep working . Also i noticed in cpu-z that the DDR400 ram (DDR333 sticks removed ) was working at 200 Mhz while it was working at 133 Mhz previously for some reason ( with DDR333 sticks in place ) . Plz help .
