|Tell us the make and model of your brand name system. |
The specific model of a brand name system is shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available, if Windows is still working, on the subject computer.
For Dell computers, they have a Service Tag number - the specific model can be determined by using that on their site, or can often be determined there automatically by you downloading some software, if Windows is still working, on the subject computer. The Service Tag number should be on a label on the outside of the case, probably on the bottom on a laptop, often but not always on the back on a desktop, and is often also shown in the bios Setup.
For Dell computers...

Tell us what it is.
The message was probably about DLL IWDPAGINA.DLL, as in,
The Default Windows Logon Interface May Not Appear After Installing Third-Party Program http://support.microsoft.com/kb/302346
Winlogon may fail if the third-party Gina.dll file is missing or corrupted http://support.microsoft.com/kb/164486
You probably have an Intel wireless adapter and something in it's software is corrupted or missing - it isn't necessarily IWDPAGINA.DLL - sometimes Windows generates a false message when it can't tell you what the problem is.
Remove any bootable CDs or DVDs from drives.
Press F8 repeatedly while booting, do not hold down the key, starting very early in the boot sequence.
When the boot choices menu appears (white text on a black screen), choose Safe mode.
If that gets you to the desktop screen, go to Device Manager and look under Network Adapters - there is probably the name of an Intel wireless adapter there. Copy it down. Tell us what it's name is.
(RIGHT click on My Computer - Properties - Hardware - Device Manager)
Does it have a yellow ? or a red X beside it ?
