Help XP Black screen on boot. 1720

Working on a 1720. Coffee was spilled on it so I got a new motherboard. Installed the mobo and it was working fine first boot. After it ran for about 10 mins it shut off. After that I couldn't get it to turn on. It would go black after the XP splash screen. I was able to start it in safe mode and that is it.

I have done or tried... repair boot record, rebuid boot record, repair install....

On the repair install when it would load the setup files it would go black again.... I reformatted the drive totally. It would allow me in the xp setup. It would go as far as installing devices and then again... iti would go black..

When it goes black I get nothing, no HDD activity at all, the computer just stays on, but does nothing.

Any help please.


Also the dell bios diagnositcs won't recognize my keyboard, however it is firmly attached and it works.

Ideas?

 

well....spilling coffer on the computer-WAS IT ON-if so,,,no telling what happen.....could be any number of things-

here is a notebook repair flow charts-

if you don,t have hardrive activity-maybe a power problem..might check out the wires going to the hard drive-

here are some problems with a laptop getting wet inside the case. The water contains minerals which cause it to conduct electricity, which means battery power can be shunted into places it does not belong, frying the components in the process. Second, those same minerals when dry can cause corrosion which can eat through the copper traces on the printed circuit boards. Both are really BAD news. Is it still under warranty? If so, contact the manufacturer. Even if it isn;t, contact the manufacturer anyway and ask about getting it refurbished and what the cost might be. If you choose to do neither of these options, you can try what a friend did when his got spilled on with a whole pot of ramen noodles and soup. Remove the batteries, the main and CMOS batteries both. This may take some doing to get to the batteries which keep the CMOS memory alive. Once all power sources are removed, remove the hard disk. The hard disk has a sintered metal vent which lets air in and out, and will also let water in. Next, give it a bath in DISTILLED water. With the hard disk, instead of immersing it, locate the vent and put a small piece of tape over it to keep the water out and then pour distilled water over the circuit board part. Take the tape off the vent after you blow out most of the water from the circuit board area. The idea is to dissolve out any minerals still inside with pure water. After a thorough dunking several times he used compressed air (no need for the canned stuff, any source will do) to blow out most of the water and then he parked it under a box with a light bulb which warmed the area, but NOT hot, just a little warmer than the room air, and then a small fan to circulate the warm air in and around the parts. He let it sit for a week, and then, thinking better safe than sorry, let a 2nd week go by. He put in the batteries and viola' it started up! This was a very risky maneuver, but he had absolutely nothing to lose. The machine was going on 10 years old. I watched this process and was totally amazed when it actually worked. I was quite the skeptic. While I was in the Navy, I had expereince with equipment which got wet with salt water and our success rate on the water bath method of recovery was about 1 in 3. Your best bet is to have a refurb done by the manufacturer.

 

I bought and installed a new motherboard. I cleaned all other parts with 99% alcohol and tested them in my other system. All components were working fine. I tested the HDD with seagate's utility and that was also fine, but it seems like a HDD problem. I bought another HDD, should be here next week. I am going to try that.
