HP Computer HELP PLEASE :( :(

[katiecmoliver]

Hello, My hp touchsmart desktop froze (into a black and white patterned screen) while in use after i plugged a phone charger into wall socket next to the one the computer was plugged in at, but i didnt plug it into the computer/touch the computer cable or plug. so i turned it off and now when i turn it back on the computer starts up but the screen stays blank (nothing loads up at all). at the time my usb memory stick was plugged into the computer and i removed this only after i had turned the computer off. could this be due to overheating as i had the computer on for several hours working before this happened? although it is usually left on (sleep mode) nearly all the time. is there any way that i can fix this quickly myself (lots of uni work due in tomorrow etc) any possible solutions/help or even if anyone knows what the problem may be would be greatly appreciated!!! if anymore details are needed for anyone to suggest a solution i will tell you but i think ive pretty much covered everything that happened to it! i dont really know what category this falls into so ive just put it in the systems one is as i am very bad with computers so im hoping someone can help please!! if i have posted this in the wrong place (which i almost definitely have) can someone please correct me and tell me where the place to post it would be? thank u :)

Hi Katie and welcome to ExTS :)

 

Have you tried your monitor on another system to make sure that is OK ?

 

Does Windows boot up ( without graphics ) in other words do you hear the Windows Chimes that indicate that your system is ready for use?

 

Do you get any POST beeps at all ?

 

Switch on and constantly tap F8. ( about once per second )

This normally gives you the Advanced Startup options - can you see them ?

 

Having verified that that the monitor is OK .........

 

Take the side panel off.

If you have not been inside a case before it is not as complex as it looks.

 

Switch off at the wall but leave the plug in. This maintains the earth connection to the motherboard.

 

Locate the CMOS battery.

It looks like a silver coin.

Take this out for about a minute then replace. ( Note the + is on top ).

This will reset the BIOS to default settings.

 

Try again.

 

Take the RAM modules out.

You do this by releasing the white levers at either end.

 

With the RAM out - switch on.

 

Do you get anything on screen now?
