computer wont boot up

[mikepp]

I have a custom built computer. I run windows vista ultimate. here are the various parts:
ram     2gb corsair dominator  2 x 1 gb sticks
psu      850 w   ocz   new
processor       intel dual core e6750
750 gb hard drive

the problem is my computer wont boot up              I turn it on and the fans start and thats it. Now i just downloaded updates this morning.           This has happened before and my power supply was faulty. this is a new one.         also this morning windows kept shutting down my computer    a blue screen came up and said windows has detected something that might hurt the computer.         I didnt see the diagnostic but one word was "memory".  any ideas??   thanks.

Try to boot with just one stick of RAM; if successful, get Memtest86 (http://www.memtest.org/) and run it on that one module of RAM for at least 2 hours; if no boot, swap out RAM sticks and try again to boot; if  successful, do Memtest86.

Test both memory modules individually at least 2 hours - or until errors show up. If each module passes individually, test both together in your normal memory configuration for at least 2 hours, preferably overnight.

Best of luck!

I tried booting with one ram stick out and then the other but still didnt work. I have removed the video card and tried a boot, I have also tried it with the hard drive disconnected. The only card I havent removed is the tv tuner card.

I have also tried it with the hard drive disconnected.

What are you booting from?

The only card I havent removed is the tv tuner card.

Any reason to leave this in when you're trying to diagnose a problem?

In your various attempts to boot, have you gotten any error messages? Can you give us the exact wording?

[mikepp]

There is no wording because the monitor stays blank. Nothing comes on except the lights and fans. The screen stays absolutely blank. I will try the removal of the tv tuner card after work today. The only indication I had of a problem was when windows shut the system down because it said it detected a problem which could damage the computer.   the only diagnostic word I got was "Memory" before the screen went blank.

Without the hard drive plugged in, would you still get the BIOS??  I dont even get that.

... I have removed the video card and tried a boot,

Did you revert to onboard memory here? Plugged monitor into MB video port?

What video card do you normally use? Latest drivers?

[mikepp]

No I had to disconnect the monitor for the test. Its a dvi connection and the monitor has rgb, but i cant find an input on the back of the computer other than whats on the video card.  I listened for the beep which would have told me the computer would start, but nothing. The video card is nvidia  EVGA geforce 8600 gts 512 mb.  I downloaded the latest drivers for it two weeks ago.

I have now tried it with the tv tuner card out   and retried it with both sticks of ram out and still nothing. I dont know what else I can test.

[mikepp]

I should mention the MB is Asus P5E.

Looks like others have had the same or similar problems with this board; look here: http://forums.anandtech.com/messageview.aspx?catid=29&threadid=2146993.
And here: http://vip.asus.com/forum/view.aspx?id=20080706094634968&board_id=1&model=P5E&page=1&SLanguage=en-us

Note the comments on RAM speed, BIOS, CPU compatibility, clearing CMOS, etc.

You didn't say how long that you've had this board, but, ultimately it may be that the board needs to be RMA'd.

I think that I'll duck out now - sorry that we couldn't get you going. Perhaps someone else has an idea.

Best of luck.

[mikepp]

thanks for all your help. I may return the board and ask for a refund or another board type. I have had it for about five months so its still under warranty. Once again thanks for the help.

Seems like the RMA route may be the way to go - a shame, you had a nice system spec'd out!

I think you should just check your power supply. Because most of the times screen becomes blank due to failure of it. Just give me a feedback of it.

Hi…
I read your problem. According to my knowledge there may be problem in your RAM. Because the maximum problem will created by the RAM like windows is restarting automatically and windows is hang so I suggested to you replace RAM.

You just replace the 3V battery in CPU.
It is inexpensive.
