Do you think my mobo is fried?

Specs: Windows XP
Hi, I had recently tried to add 2 512MB DDR2 RAM memory sticks to my old HP pavilion 533w and somehow after countless minutes of trying to get the RAM to go in (I had it facing the wrong way) and turning on my comp, it wouldn't start. Now I didn't really care enough to check if it would hold the DDR2 (the computer is old, not THAT old) so I figured it would take DDR2. Long story short, I ended up just putting back in the old RAM that was in it because by forcing the newer RAM to go in I accidentally broke the clip snapper (the piece that snaps and holds the RAM in place).

Now by not starting I mean it actually doesn't start. I'd press the power button and it the fan and lights would come on for a second then just quit. I made sure I grounded myself before attempting to put the RAM in. I also made sure that everything was plugged up in their correct sockets just incase I may have accidentally snagged something out. So do you guys think I fried my mobo somehow? or maybe my PSU died? The computers old, but it was still working pretty good before I tried to add the RAM. Kinda bummed out...Any ideas? :\

Well what kind of ram did it have before?. It would be helpful if you provided make/model number of the motherboard.

if this is you machine:

it takes DDR not DDR2, you likely destroyed it.

"didn't really care enough to check if it would hold the DDR2"
took a 2 min google search, to find out, or you could have posted here first. You ended up posting anyway.

When you took the original RAM out, all you had to do was compare it to the new RAM. It should have been obvious that they are different. DDR has 184-pins, DDR2 has 240-pins, not only that but they are notched differently. And if you would have compared the specs, you would have seen that your original RAM (DDR) requires 2.5v while the new DDR2 only requires 1.8v. Your "didn't really care enough" attitude just cost you a lot of money. You broke the RAM slot & most likely fried your motherboard. Probably fried the new RAM too.

You're installing the wrong ram may not have damaged the ram slot circuits, but it may have damaged the new DDR2 ram.

However.....

"countless minutes of trying to get the RAM to go in (I had it facing the wrong way) and turning on my comp,..."

....if you tried to boot the computer when any ram module was backwards in the slot, the ram that was backwards and the ram slot it was in are both instantly fried, both can never be used again, and you would probably have noticed a distinct smell like the smell of burnt plastic. If the ram module is damaged you can see evidence of that on the contact edge - damaged or missing (they were vaporized) contacts. If a ram slot is damaged you can see evidence of that in the ram slot - black carbon deposits, the plastic has been melted in places, damaged or missing (they were vaporized) contacts.

In that case, you MAY be able to get the mboard to work again if you install undamaged DDR ram in the remaining good ram slot(s), if you use good lighting and clean up the damaged ram slot(s) - remove all carbon deposits, melted plastic that is bridging contacts.

Thank you all for the replies. You guys are right, I probably did fry the motherboard by trying to replace the older RAM. Gah, stupid mistake on my part :\. I honestly didn't feel I needed to check if it could hold DDR2 and because of that I guess I cost myself more money than just checking. It's all good though, and thanks again for the help.
