You can upgrade, your RAM, with the same voltage, and brand, but also brands like Kingston, or Samsung, Corsair, are good ones! always, look on places like best buy, or radio shack for those. I prefer new RAM instead of used.

If you have lost your password, try remembering it using the hint.
If you can't remember it, there is a password to unlock user password, but still now nobody knows what it is, try searching in the Internet, maybe you will find it.

If there is another user in your PC, you can go inside it, and recover your password via a software called Network Password Recovery Wizard 5.4

Happy Recovering ;)

The beep pattern tells you what is wrong. Search Google for the exact pattern...ie 2 short beeps, 2 long beeps, etc. Could be bad RAM chip or bad motherboard or video card, etc. The beep pattern will tell you what needs to be fixed.

Do you mean when you just tap the pad w/ ur finger? if so this is a setting that can be turned on and off. Have you or anyone been pilfering through the settings?

The wireless router has a rest button, just reset it, you will need to reset security, if you use it.To rest ip, you use ipconfig/all ipconfig /releaseipconfig /renewexitBut if you just reset router, repower this and the cable modem, you should see the wireless, then if you have to, open network and sharing, change adapter setting, disable and enable the wireless hardware.

Hello Joresnore,
When booting to the XP install disk you should arrive at a "Repair Install" option that will not format the HD (I am reasonably sure it has to be SP2 though). It will just overwrite Windows system files, .dll's , etc... I think this is only available when using an XP SP2 disk so if your installation disk doesn't contain SP2, I would look for one that does and give it a try. I have had multiple successes using the repair install method without loss of data.
Good luck.

The error PXE-E61: Media test failure usually means the hard disk has failed or the hard disk needs re-seating or the disk controller is faulty. First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty. Next - to check if the hard drive is faulty, remove the hard drive and insert it into an USB hard drive adapter and connect it to a working computer's USB port. If this computer cannot see it as an USB mass storage device and you cannot open the various folders and files on this drive, then this confirms the hard drive is faulty. Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

Some later model wireless routers have the Password(ie.Encryption key) and the SSID already configured in the wireless router andthis information is printed on a label on the bottom of the router.These settings can be used to configure the wireless card and wireless adaptersin your computer/laptop. If these settings do not suit you, then it can be changed to suit yourrequirements. The encryption key secures your data and wireless connection from unauthorizedaccess.To configure the wireless settings in the router, connect a LAN cablefrom your computer to the wireless router, then open a Browser on your computerand enter the router's configuration IP address, then enter the admin login andpassword and then go to the wireless settings and configure the SSID and Encryptionkey.The router's encryption key can be a Passphrase or the WEP or WPA or WPA2key.If you use the Passphrase method select either WEP or WPA or WPA2 togenerate the encryption key. You can enter the WEP or WPA or WPA2 key with 8 to63 ASCII characters or 64 Hex digits.Most people use Passphrase which is easier to remember eg. I was born inJanuary 1988.The strongest and latest security is WPA2, the weakest and oldest is WEP. To connect to your wireless router from the computer/laptop,configure the wireless card in your computer/laptop with the router's wirelesssettings ie SSID, plus the WPA or WPA2 encryption key. Then computer/laptopscan communicate with your wireless router.http://www.fixya.com/support/r10267861-network_security_key

Remove the main battery, now try the power supply, is there any change?

Laser is starting to go bad in your drive. Replace the DVD-RW drive.

Try another DVD-RW drive because it sounds like the laser is going bad. Burning requires alot of power from the laser. Playing DVD or playing cd's doesn't require much so thats why it would play those.

hiare you able to play anything on this DVD player ? try video/song you burned on it last . if it doesnt play, you will have to replace the DVD burner

Yes, go to Start>Control panel>Power Options. There also should be a screen brightness key on your key board, that looks like a sun shining, with arrows pointing up & down. To use that key, hit the FN key, right next to the Ctrl key. Push & hold the FN key, while pushing the up arrow. That should increase the brightness of your display. Good luck.
