my computer go slow :(

[deamonic]

at current i cant play doom legacy or skulltag because my main computer is going at extremely low speeds, but other games (some new, some old, all SUCK!) are working really well while all my good gameplay stuff is running slow as hell. a few weeks ago we had to get its mainboard (not motherboard) and copacitors (hope i spelled that right) replaced, but before it broke it was working fine, now when its fixed its working like shit. any idea what the problem could be?

other notes:
1.any virussy-software was deleted, but ive reinstalled most of the slow games and theyre still shit.
2.model-based GL games are running smooth, while sprite-based (like doomlegacy) are running like shit.
3. skulltag is okay untill bots or other players are added, then it becomes a low framerate that used to be a game.
4. this is weird, but the smoothest running game is the unreal tournament 2004 demo, which is probably the most graphically enhanced game weve got.

What do you mean by mainboard if not motherboard?

What capacitors where replaced and where (it's very odd that someone replaced them, you dont hear of it often)?

[deamonic]

the capacitors leaked acid on the mainboard, which i think is at the back of the computer, and it has all the serial ports. we had to have it and the capacitors replaced. they deleted anything on the HD that had a virus, and i suspected that part of the legacy/skulltag files had to be deleted, but that wasnt the case cause i reinstalled poth ports. aparrently some electrical cords or something got burnt out and the computer shut off automatically at startup, but that was supposedly fixed so i dont know what the problem is. im gonna try reinstalling the driver incase it had any damage in it that had to be deleted.

First, I question your saying "we had to get its mainboard (not motherboard) and copacitors (hope i spelled that right) replaced". Capacitors when they leak, is usualy a rubbery or crystalline substance that gathers around the top of the capacitor. These capacitors are soldered to your mother board. There are larger ones in the power supply also sodered onto a board. Your extention cards also have them. These days, As Planky said, they are not normaly replaced and you would normaly just replace the board, card or PS. Chances are they would damage the board further by trying to remove and solder in new ones.

Second, A Mainboard and Motherboard are the same thing unless you mean the "Riser" (a card that plugs into the motherboard that the other system cards plug into).

Some motherboard makers use a CMOS battery that is soldered in place and looks simular to a capacitor that could leak acid. Battery acid will damage a circuit board or any other part that it leaked onto.

Anyway, best thing to do is to just replace the part that has leaking capacitors or any part that the acid has leaked onto.

they replaced it, so i think the slowness has something to do with the virus scan, that deleted anything buggy. mabye something was bad in the graphics driver...

the only thing the appears to have been replaced is the bit at the back where i would plug the non-USB printer(which we got rid of a while ago). they also said the fan was crammed full of dust or something else, but i think they cleaned it out. right now im just wondering weather part of the graphics driver having stuff that had to be deleted on it would be possible.
