My computer doesn’t start, when I start it, makes different sound? How can I solve it? Urgent, please?

Thank you in advanced!

I am using a P4 machine of DELL brand having Intel brand processor of 3 Giga, the issue is that the processor left working when i browse more than three websites in my Mozilla Firefox. Can anyone please tell me its solution in an easy way, thanks in advance for support.

I heard that Windows 7 is virus-free. How much should I trust this? I am planning to buy Windows 7 but I'm really worried about virus problems.

I am using DDR2 RAM and 2.5 GHz processor.

When my computer boots,  it shows the "Over Temperature"  message.

After sometime my computer turns off.

If I open RAM and insert RAM, my pc will start for one time.

Again the problem occurs.

What is the solution about this?

Hi All,

Just had a HDD die on me, so bought a new one, installed it and all works fine except my laptop isn't recognizing my Graphics card. Keeps telling me its a VGA.

The problem is before my old HDD died, I didn't write down what model my GFX was. I know its a Mobility HD 5xxx something, but that's all I remember. Have tried downloading different drivers, Intel doesn't recognize it, which makes me think its AMD.

My laptop is a Toshiba Satellite L650 OFN.

Any help would be appreciated and apologies if i have put it in the wrong section.

My pen drive is 8GB of Color Turn brand.  When I connect it in my computer an Message came, "You need to format the disk in drive G: before u can use it". But when I click format. Then it starts at last my computer system showed me an error, "Windows was unable to complete the format".

I am using Samsung CRT monitor.

If I work for a long time such as one hour then the display of my monitor reduce almost half or one inch from both side.

After one and half hour it turns off.

What is the problem and how can I solve it?
