BSoD and no more booting my pc

Hi,
I have this little problem. When I started my computer yesterday it was awfully slow for some reason, but when I wanted to play a game it gave me the blue screen. This said that is was dumping the physical memory. When it was done my computer shut down by itself and tried to reboot, but nothing happenend when it was rebooting. I could hear my fans working and my HD working also for a short time, but my screen didnt do anything at all. Normally when I boot my pc I hear some distinctive beeps, they were gone also.
Now, I've read trough all the possible problems and fixes but none seem to describe mine.

What I've done is I unplugged all my cables and my HD. Replugged my powercable and gave my computer a boot without anything except the powercable. When I did the beeps were back, then I shut down my pc and plugged my screen and keyboad/mouse back in.
Then I booted my pc again, I saw the bios flash screen and was able to get in my boot menu by spamming F8. The HD was still detached.
I shut down my pc again, plugged in my HD, spammed F8, chose my HD and it would start again. I chose to start it in safe mode to restore my back-up. Then while I was working my way to the restore page it froze on me again. (without the BSoD)

Now it wont do anything at all, it only starts my fans and thats it. Even when I repeat the same as stated above. Even when I pop in the restore disc I got with my PC. it just stays black =(

So guys, is my HD broken, my motherboard or my RAM?
I cant figure it out, can you help me or do you have suggestions?
Thanks in advance.

Hello welcome to the windows7forums,

Open the case and take out the battery, wait a couple minutes, then replace it.

Also change the jumper of the board for the CMOS, then return it to it's original position.

If your hard drive is not making a clicking noise, I'd say you're alright there.

What is CMOS and where can I find it?
I removed the battery and replaced it but with no luck
still nothing happens when I start it.

Did I mention to unpiug the computer's power cord first

It should be fairly close to the battery.
There are not many jumpers at all on the board.

Look for a jumper that has one pin inserted and the other pin exposed. Switch the order, turn on your computer, shut it down, now place the jumper back on the original pin it was on.

This should reset the BIOS

Get into the BIOS and check and make sure the hard drive is second in the list to start from (CD-ROM first)

Ok so i've done it all but still it wont boot. The fans keep spinning but nothing on the screen.

So it go through the post to the black screen?

Is there a cursor on the black screen?

If so, Tap ALT-CTL-DEL to bring up Task Manager, choose New > Task, and type in explorer.exe.

There is no cursor. My mouse and keyboard dont light up either. Its all black.

If your mouse and cursor don't light up, you're not even getting past the POST.

Very series.

I would open up the case again and make sure every connection is tightly inserted and plugged in correctly.

Well thats the thing, I've triple checked all the cables. I even disconnectes them all and reconnected them. Been staring at an open case for a long time now :P

I dont have another pc at hand sadly. But I disconnected my dvd-player and started my pc again. No bleeps but I did hear my HD starting to read. So did this rule my HD out or do I really need another pc?
