From another computer, Google-search for "Nordahl password".
There is a CD-ROM that lets you boot from that disk,
and then "blank-out" the password for the account.
Then, restart Windows, and leave the password field "blank".
Then, when Windows is running, set a new password, and create a new password-disk.
Watch the screen as it boots up looking for the press F1 or DEL to access Setup. Your Presario may not be able to see the new HD in which case you will have to run second party software to access the HD. Get into the Setup BIOS and check for your new HD under hard drive detection if the BIOS can not find it, you will have to run other software to access the drive. If your BIOS gives you the option to start up the hard drive after a delay such as 1 or 2 seconds try that, as the BIOS on the hard drive and the BIOS on the motherboard may be clashing. Hope this Fixya up
Power up the external monitor first and then boot up the laptop, the video info will automatically divert to the external monitor. If you do not see a Windows image on the external monitor then it is definitely a motherboard issue, because the video card is built in on the motherboard. The Video card uses shared RAM (part of the RAM module/s ), try re-seating the RAM modules, also test the RAM modules. You can test the hard drive by removing the hard drive and connecting it to an USB hard drive adapter, then connect the adapter into a working computer's USB port. If the hard drive is OK, this computer will see it as an external storage device and you can open the various folders and files on the hard drive.
ok, this is a muti step process. 1. Remove the hard drive and push the power button. When the HP screen appears enter the Bios. This is usually done by pressing ESC, Del or F1 when the computer displays the HP screen. If you get into the Bios open and insert a bootable CD/DVD close the drive door and let teh computer continue to boot. If you don't have a disk handy you can get Knoppix, a Linux OS designed to run from DVD/CD, at most used book stores for about $5. If the computer starts your problem is the hard drive. 2. Assuming the computer did not boot. With the hard drive out, remove the RAM and repeat the steps above. 3. If the computer still fails to boot remove the CD/DVD drive and repeat. At this point you can reinstall the hard drive and RAM. Your goal here is to remove items until you locate the one that is causing the problem. Since you have already replaced the motherboard a second time you are pretty sure your main board is good so it must be a different device. The most likely fault is the Hard Drive followed by RAM, CD/DVD drive, MODEM, WiFi and so forth. Once the computer boots with a specific device removed you know that device is at fault and replace it to resolve the issue.
That sounds like a cpu, ram or motherboard issue. The cpu could be bad or unseated, the ram could be bad or unseated and it could be anything on the board.
Gnerally the common thing that will cause it not to boot and not show any error or video etc will be ram. That is where I would start. You can try removing any modules or just trying one at a time or in a differant slot. Ram is cheap(ish) right now so it would be worth fixing if that is the cause. You can replace the cpu or swap it out. Replacing the motherboard requires it be stripped down and you may find a new motherboard for $150-$200 and then the labour on top. Better check for any warrenty if possible. And if you need to pay out of pocket consider getting a replacement laptop. New ones have dropped down enough that the repair cost could be as high as replacement.
Do you see anything on screen? Dell logo? I will assume you see nothing. Not even a Dell logo.
First test your power supply with a meter to be sure it is putting out 18-19 volts. If good, remove the laptop battery and try again. The next tests should be done with the battery not connected to the laptop.
Remove the hard drive and see if it boots. If not, next remove the dvd drive from the laptop and try to boot. If no good, remove the ram, clean the contacts on the ram and the slot with a pink pencil eraser....gently, just make them shiny. Try to boot with no ram/hdd/dvd. Put the ram back in and try again. Try connecting the laptop to an external monitor.
If after all this you still cannot get a Dell logo at boot time, the mainboard is likely dead. A refurbished one (with only 90 day warranty) will probably cost you at least $250 from Dell. Please let this one go and look at a new laptop.....sorry.
first let's determine if the upgrade cause the boot speed.
Disconnect your NEW HDD and/or memory, one by one and see if you get back your fast boot. Then try with your NEW components only !
If you find it works better with new components only, then first connect your OLD HDD only and try.
If you connect both HDDs on one cable, check Jumper settings for both HDDs (Master/Slave).
Also HDD capacity and type is automatically detected by the BIOS and there is no need to put/change those settings manually.
I believe you new RAM is DDR type, too! As written in the manual for the board, your motherboard has two pairs of memory slots, and you can use one or two modules of DDR memory, OR one or two modules of SDRAM memory, but you can NOT put BOTH DDR and SDRAM memory modules.
You could have a faulty motherboard or RAM.
First remove the main battery and boot up the laptop without the main battery connected, if it boots up insert the battery, no need to power down. If that doesn't work, switch off/disconnect the adapter and insert the battery, then reseat the RAM modules and boot up.
If nothing works then you have a piece of junk. You can salvage the hard disk and put it into an USB hard drive adapter case and use it as an external USB hard drive.
OK, so I took out the added RAM, changed the internal RAM to a new 1GB stick. The machine booted, windows started, I logged on, then blue screen. I put the old internal RAM back in, changed the hard drive, same result. This test suggests that the RAM is fine as is the hard drive as the blue screen appeared with different hardware. My next step is to replace the motherboard as the appears to be the issue. I'll let you know how I get on.
