Question about Computers & Internet

Computer won't load past Boot and now doesn't display anything!

I have a custom built computer, with an A8N - Sli motherboard (quite old) It has 2 Nvidia 6600Gt Graphic cards in Sli. I also have 4 sticks of 512mb DDR 400 Veritech RAM.

Im not sure what cpu i have but i havent touched it. Recently for no apparent reason my computer would get stuck in a loop.
I would start it up, it would go past the BIOS startup, and then it shows the Windows Xp boot screen, the line goes past a few time and then it restarts and does the same thing forever. It may show a blue screen but it is too quick to read anything.

When I was researching this there was the suggestion that the RAM was stuffed up, so I removed all but the stick in the DIMM A1 slot.
I disconnected everything using an old keyboard an screen. When I tried to re arrange and try a different combination of RAM i cant fully put in the Ram modules. the Sticks dont go down completly and the clips dont close when i push it down.

So i cant put in the Ram
i still had one stick of RAM in it though
So I tried to start the computer up.
But now it wont display anything. I tried my newer screen which i had in it before and worked fine, i tried putting them in the other graphics card

I have not really done that much pulling apart of computer, so I dont know exactly what is wrong.

I hope that I can just get a display first, and then put in the Windows XP disk (its running SP3)

Thanks for all your ideas in advance

Feeling depressed as I cant play anygames anymore as it was our UBER OLD gaming computer!

SPECs of it:

2 x 6600 GT
A8N - SLI Asus Motherboard (im not sure
some AMD Athelon 64 CPU running somewhere around 2.5GHz cant remember exact
Soundblaster Audigy 2ZS Soundcard
Antec 350 Watt (came with case i think)
and 4 x 512 mb DDR 400 DIMM Veritech RAM

Please help me! thanks

    I have copied the direction in which the RAM is facing with the first stick which is already properly in

    Also I am still not getting any Display on my Screen
    It just says NO signal, or No imput

    IT wouldn't boot so I research and then somebody commented on how it may be the ram so I unpluged all plugged in a different screen the display was still working. So I pulled out properly 3 sticks leaving 1 in the DIMM1a slot then the display failed. I tried different screen then tried to put in the other sticks of RAM but I couldn't get both sides of them in. I'm about to go to sleep now but any suggestions on the display would be good. That's first priority.

The memory stick going in one way into the module. If you can't close the clips try to rotate it 180 degrees.

when windows starts hit F8 key and select disable automatic start on system failure.
This will bring you a blue screen with the specified error

also you can boot from windows xp cd and at first screen select repair, this will put you in recovery console
in recovery console you can scan your hardrive for errors like this:
chkdsk c: /p /r

    so you told me that first time booted windows. After you changed the memory slots, it stopped working.

    The problem is you memory. If you forced in the slot, you have big chaches to be memory damaged.

    Try with 1 memory, but be carefull, don't force it pushing.

    this is bad.

    Probably you damaged your RAMs or your motherboard

SOURCE: Install DDR-DIMM PC3200 to MS-6367 MSI

That motherboard was made for PC2100 DDR266. A PC3200 DIMM *SHOULD* be backward compatible. Depending on the density of the PC3200 memory you might have problems. If you have not bought the memory yet I would go with the PC2100 for sure since the PC3200 will give you no speed gains at all and will be running at PC2100 speeds anyway.

If you already have the PC3200 memory then I would say just give it a shot. The worse case scenario is your machine will not boot up with the higher speed ram installed. Assuming you take all the normal hardware upgrade care and do not physically break anything you can test this memory with no harm to your motherboard.

Non-stop beep sound and won't display

A constant beep, usually indicates the post is detecting no memory installed. This is usually caused by the memory not being installed correctly or incompatible memory. double check you have the correct memory for this mother board. If you have 2 chips, install one and test. If this does not work swap the memory and try again. If both chips fail, you might try a different brand of memory.

Does not boot up into Windows

This very well could be a motherboard problem. I would suggest removing the CMOS battery from the motherboard and looking for the "clear CMOS" jumpers which should be close to the battery. They generally are 3 pins, a jumper across 2 of them. Move the jumper to the other setting for about 30 seconds and then replace. (do this before removing the battery).
Then take the battery our for maybe 30 seconds and replace it. Try to start. If that doesn't work, I think you BIOS may be corrupt and you'll need to go the the ASUS site to get a new BIOS file.

No PS/2 keyboard response on boot.

Try a different keyboard and then try a different mouse. Try unhooking the hard drive and see if it goes past the logo, if it still doesn't then go ahead and disonnect the keyboard and mouse and see if it goes past the logo screen. If it doens't go past the logo then take the memory and cpu out and blow so air onto it to make sure specs of dirt or dust are no affectng it.

you can also try different memory as well to see if it stops locking up. Otherwise if you go thru these steps and you still have the lockups, its not going to be the keyboard are mouse causing the problems, its the motheboard.

You can try a usb keyboard and it might work but that would mean you have a bad ps2 port on the motherboard and as long as that doesn't bother you then the computet will be fine.
