Probably what happened is a virus got in during the download.
The easiest way to fix it is to boot from a virus free system disk and clean your hard drive from a programme like Norton Anti Virus. I don't think Microsoft Essentials will do it, please correct me if I'm wrong.

There are a couple ways to fix this , 1. When you turn on the computer as it's booting up start pressing the "F8" button on your keyboard , your pc should load up to a black screen with several options in white text to choose from , try "boot using last known good configuration" , if that is unsuccesfull repeat the previous steps & this time choose "boot safe mode". If you can at least get it to boot into Safe Mode you can undo / repair the changes that occured .

2. If you can't even boot Safe Mode , you can try booting your pc using the operating system installation disc / recovery disc that came with your pc . Once loaded you can select to repair your current installation . Then sit back & wait till it's done , it will reboot & you should be presented with your login screen .

Cant view internet everything freezes cant even close it down when it freezes


You will have to start in windows safe mode with networking install malwarebytes at filehippo.com
make sure you update it after installing then run scan after that you will reboot to normal screen and then you will run it again i suggest that you run the quick scan first on both the safe and normal modes if that does not fix you problem then you will have to run the the other scans and they can take a very long time about 90% of the time quick scan solves the problems.

Dell Inspiron 1525 Laptop..the screen goes almost black after 5 minutes.


The screen goes black while in normal mode right? So try to boot in safe mode (power on then keep tapping F8 then select safe mode). Check if still happens in safe mode.

If screen does not goes black in safe mode it means there might be a software or driver causes problem when running in normal mode. You can try the following (update your anti virus software then run a full system scan, uninstall the video driver then download and install the latest one, uninstall any previous windows update or you can system restore to the time when it was working fine).

If the screen goes black even in safe mode they try connecting the laptop to an external monitor if still goes black, if yes then absolutely no issues with the LCD panel. You can try (uninstall and reinstall the video driver if still persist then this might end up replacing video card or motherboard, but before doing that update the BIOS first).

If does not goes black in ext monitor then the LCD panel might causes the problem. Reseat the LCD cable or inverter if you can.

Sounds like the laptop is trying to display a resolution that is not supported. Try to reboot into safe mode or the BIOS. Try safe mode and if you can get into safe mode make the default screen resolution something like 1024 x 768, then reboot and see if everything comes back.

When I turn it on I get three beeps and nothing else


Hi,

The 3 beeps are correct diagnosis for the screen problems.

reboot, keep tapping F8, till you get to
the start up screen ( black dos screen )

Try the last known good first at the top, let it roll.

If this fails, try safe mode, let it boot up, then try a system restore,
start,all progz, accessories,system tools,system restore, try go back in time.

If you cannot get into the "black" start up screen at all, your video card, has failed.

because you should get minimum of VGA graphics in safe mode.

if you do, then the video driver is corrupted and needs updating

Regards
Richard.

Cant get to reboot in safe mode


Trying pressing F8 about every 5 seconds from the you turn the computer on any faster and this will give a stuck key error. This should put you in safe mode.
