Gateway screen comes up; optical and (new) hard drive spin up, both drive lights light up during this time, fan spins up and air moves out of the side vent continously but still nothing but a blank screen. During boot I can press f10 and then press pause key to read screen- 2gb memory recognized and passed, drives recognized, T5500 processor detected, system bios shadowed, video bios shadowed, mouse initialized, bios version 77.06, system id = (blank). All this and nothing but a blank screen afterwards and no activity.

could be light from another source reflection or check to see if you hear or feel spindle spinning in drive? if so, then power may be misrouted to drive somehow or drive is not connected correctly

3 BEEPS -RAM

Guest Posts: n/a 01-24-2005 We had a power failure in the office this weekend. All the systems are back
up and running fine, except for the receptionists. It's a Gateway
Professional Series. P4 1.3 Ghz. It is giving me three beeps. No boot up
screen and no video source (monitor light stays yellow instead of turning
green). I looked up the beep code and it says three beeps means the ram
needs reseated. Which I have done several times. Also, I have just put in
one stick in difference seats. I have also reseated all the cards at least
three times. I have switched the jumper to try to boot into setup mode.
Nothing there either. Popped out the cmos battery and put it back in. No
good either.

Has all the ram been fried? The fan on the cpu is still spinning. The cd-rom
ejects. I can't hear the hard drive spinning. I guess I can swap the hard
drive for a different one.

Anything I'm missing? YEP

sounds like your system is booting up and running due to the hold power shutdown procedure. you might try replacing the video card or adding one if your video is integrated.

Power problem with-in the motherboard, the spinning sound is not hard drive, it is the processor fan that spin in boot-up then stops. You have faulty motherboard chips. required to bring it to repair shop for preventive/repair.

Yes, if the CPU/motherboard will not POST (Power On Self Test), then changing the CPU is the only thing that you have not tried.

replace then.

dear it is damaged...please replace....when this message show then memory card is damaged and not readable or not writeable.

Clean first its ram module edge connector with soft eraser. But disengaged first its battery, power source and completely shutdown.

Then put it back and try to boot. If this doesn't help let me know . Leave a comment.

Probably the mainboard or flaky power supply.

I'd start by replacing the power supply. Buy one you can use in a new machine, though... or "borrow" one from another machine.

Hello,
You might want to get your ram checked. Not all the time does a computer beeps when a memory is bad. Also, if you have tested the memory ok, then try another power supply, if that one is faulty, it will not be giving enough power to show on monitor. If that still isn't the problem, then it could be your video card. The way you will know if it's video card is that the keyboard light will be lighted but nothing will show on the screen. To test that press the num lock or caps lock key to see if it gets lighted. if it does, then the problem would be the video card.

Thanks and good luck. Hope this solves your problem.
