Overnight drop in framerate

I recently managed to acquire a new PC, well new for me most of the parts are fairly outdated. Anyway, its only to do as a replacement until i can afford another, better one, but ive noticed that it has quite a problem with games.

Now by no means is the system a great system, but the error im getting is unplayable FPS in nearly every game.

System Specs-

Asus P5ND2 Sli Deluxe Motherboard
Intel Pentium D 945 Dual Core CPU @ 3.4 GHz
6GB RAM
Zotac 9800gt Eco
450W PSU
Win XP 64-bit

Now, the MB, CPU and RAM all came as a bundle together, and the previous owner said that, albeit with a different GPU, he could play Skyrim on the system. The GPU came from a friend of mine, who could play numerous games without an issue, even though his system is roughly the same as mine.

Upon putting the PC together, installing all drivers and software and everything else necessary, i tried a couple games.

Results were, with Nvidia Control Panel 3D settings around medium (4X AA, 4X AF, etc) and in-game settings maxed out, i could play Amnesia (Not exactly an intensive game) at 40-45 FPS. I also tested Arma II/DayZ and a couple other games, at the same Nvidia control panel settings, and ingame settings for Arma II/DayZ at around medium, and in fullscreen, and i could get a rough 30 fps.

Things seemed fine, up until i tried to play the same games a day or two later when everything seems to run ALOT worse.

Now i can only play Amnesia at a mere 20-25 FPS, with ingame settings at low/medium and everything in nvidia control panel at off or lowest. DayZ with everything ingame at lowest and same with nvidia control panel im getting at the very very most, 15 fps,even in fullscreen at some randomly low resolution. Now even though days prior i was getting higher FPS even at higher settings, my average fps has plummeted, even with dropping graphics settings, making sure no background programs are open, and even running the games through gamebooster which gives me an average of about 37/40% performance boost.

Yeah, i realise that the system is by no means great, but even my old laptop (Intel i3 2310m, 4 GB RAM, Intel HD 3000 Integrated GPU) could run these games fine and at higher settings than what i can run the games now (Although before the drop in fps this PC beat it).

I am stumped on what could be the problem. I have re-checked all drivers, i have scanned the PC for viruses (Twice, even though i installed the OS brand new only a few days ago when i built this system) and found none, and i have tried re-installing the games (Even though this is happening with ALL games).
 
Win XP 64bit is not exactly the best of operating systems, what i would do is if you have a spare HDD or not bothered about nuking the current drive, download a copy of win 7 x64 sp1 from microsoft and just install it and try it within the 30 day activation period to test if its a driver and compatibility problem with win xp x64.

@Sakkura - I havent really checked Hardware Temps.
@Daswhilhelm - I know the Pentium D is by no means a great chip and that the laptop was alot newer, the thing is that i was able to play DayZ on this exact PC the day i built it (And that day after) at fine FPS on medium graphics settings, but now after a few days i cant even play it at 15 fps on the lowest settings for everything.
@Mauller07 - Yeah, i would have installed Win 7 on this as soon as i could, the reason i didnt is that due to the motherboard being fairly outdated they dont have any drivers for it after Vista. Will this affect anything, or should i still try Win 7 and use drivers for another OS? Dont really know if that would work, im pretty clueless when it comes to driver compatibility

Microsoft provides quite a few default drivers for older systems/common chipsets. It will probably fire right up.

I actually have my old Athlon X2 6000 with an M2N-SLI Deluxe running on all defaults because ASUS hasn't released a driver package for it. It runs amazingly well all things consider

@Eximo - Thanks for that info. I had a search to see if the P5ND2 would be compatible with Win7 and while a few people said they had problems, the majority said that Vista and XP 64-bit drivers would work. The biggest issue was getting the Nvidia Nforce4 Chipset driver to work, but apparently the Vista driver will work for that too. Going to try Win7 and see if it'll work
