Need HELP with PC, may have died?

Question

there are a few problems with it, when i power the computer up nothing appears on the screen, i have put my speakers on and no sound comes out of them (windows loading tune), when you press the on switch to switch it off it doesnt switch off.
Does this mean it has died, PLZ HELP.

I am currently using a computer in college.

it powers up finely and ive tried everyting such as unplugging all the other wires and only leaving the monitor cable in.

well i have to hold the power on button for around 10 seconds to switch it off

well before it went, i increase the graphic memory from the BIOS from 64mb to 128MB and I increased the FSB from 100/100 to 133/133

Answer 1

So, basicly, what you're saying is....you went in a changed the BIOS settings and really didn't know what you were doing and now it doesn't work...umm...I hope maybe you've learned a lesson from this.

Why did you make the BIOS changes anywhy?
----------------------------------------------

I've come back to edit this now cus I feel bad for kind having a go at you. My bad.

Ok, here's what you do....unplug the PC from the mains.
Pop the case open, take out the BIOS cell battery.

Go make a coffee or have a cigarette or whatever you normally do to pass a few mins (you don't have to tell us, lol).

Come back to the PC, pop the cell battery back in, plug the mains back in, power up and come back here and please let me know what happens.

**It should have reset the BIOS settings and will prompt you to accep the defaults**

Please let us now how you got on, or PM me or something.

Thanks.

the fact nothing appears on the screen could be your graphics card has failed, the fact you don't hear a start up tune is probably due to it not loading up past the POST screen(where all the writing comes up) the fact that it don't switch off is a strange one unless ....... have you tried holding in the power button for about 3 to 4 seconds? does it switch of then? if so then this all adds up to what sounds like a failed motherboard. you may get fan noise still if they are directly connected to the power supply and not onto the motherboard through the three pin connections that most have(at least one for cpu fan) take side panel off,- does the cpu fan(the one on the heat sink)work? if not and it IS connected to motherboard then this is further evidence of motherboard failure, one last thing to try in this situation is- the BIG 20/24 pin retangular plug to motherboard from power supply(i assume it's an ATX system)- check it's connected firmly as this is the way power gets to the board and components such as the graphics card/onboard graphics(you mentioned no display) and the sound card/onboard sound(you mentioned no sound). i hope i've helped to diagnose your problem but it is never easy unless you can see the pc face to face! just doing my best with limited resources available.
*****************UPDATED DIAGNOSIS**************************
you NOW say youve increased graphics speed and front side bus. sounds like your overclocking skills need refinement and you have probably overheated the system which caused the CPU to shut down as a safety precaution to prevent damage. get a better cooling system and put a fan on your graphics card or that will burn out next!!!!

First check your BIOS:

When you start your computer a message appears saying "press the DEL button to activate the BIOS settings". When your computer starts, hit the DEL key continually until the BIOS screen appears. If you don't see the BIOS screen either your monitor or video card is at fault.

If you see the BIOS screen, there should be an option to "roll back" to an earlier date (restore settings). If so, select about a week ago then save (press F10, type Y) and reboot.

Another possibility is the "Halt on" error handling (again BIOS). If the above hasn't worked set the "Halt on" to keyboard and make sure your keyboard is plugged in before rebooting.

If all else fails, test with another monitor. If the problem persists it is probably the video card.

Well, First off, Do you hear any noise coming from your PC? Such as fans turining on inside the case? Power supplyfan?

If not, double check all of your power cables. Make sure that the wall outlet is working. Try pluging in a radio into the outlet to confirm that it has power. If it does, Then check your power cord going into your power supply. Maybe try a different power cord.

If you still have no luck, then I would try checking your power plug that attaches to your MOBO to make sure it is connected properly.

Last resort, Use another power supply to power up your PC.

Good luck!

Cheer!

Answer 5

If it is powering up OK surely it that the monitor isn't working? or the sound card has gone. Try to remove sound and then put it back on?
I can't see that its is too bad if it is starting up finely. Have you got a friend that will let you try their monitor just to check it. Not that i am any where near clever in the art of PCs lol i am just thinking logically. Hope you get it sorted.

Answer 6

If the sound problems occur intermittently, there could be a interrupt conflict problem. Uninstall the audio and sound drivers and restart the computer. The computer will automatically reinstall the required drivers and the problem will be resolved. For more information you can check the following site: http://fixit.in/sound.html I find the information givenin the site is more useful

Answer 7

umm. this one is tricky to answer, the only thing I can suggest is to boot (restart) your computer using a boot disk which you should have made when the PC was healthy, failing that try placing a XP installation disk in the CD-ROM drive as this has a boot up software on it,,other then that I am sorry to say you might just have to buy a new computer. very best of luck with this one hope it all goes well for you.

Answer 8

I know what your problem is...and i have a solution. Pull your computer out so you can access the back of it. Notice the monitor cord and the power cord, disconnect both of them. Now, get a can of pressurized air, ya know the stuff you use to clean a keyboard and such, and pull your computer out where you can lift it up on a stable surface. Now, very carefully, put down the can of air, open the closest window, and throw that Piece of Crap out the window and but a Mac like you should have in the first place....Now you won't have any problems :-) Have a Nice Day!

Answer 9

Try unplugging it and reebooting it then click on your start tab and go to system tools and it will have an option called system restoration click on it then it will say set to an earlier restoration date, it has a calendar on the left side set it for like a month a go u will have to select the month and date then do what it says your computer should reeboot and start back up normally. Hope I helped Tina

Answer 10

have you put your old bit back in to see if you pc will work if it does then the new bit might not be compatible with your pc , i am just guessing but it is worth a try ,

if it works then try one piece at a time, to see if it works , i am new my self to computers but like most things in life if you start at the beginning and work your way through to fault find, with experience you will then get to know where to look for faults .

pc i think are like cars they all have the same basic function but different model have different faults that is the way things are
