My god what did swapping a new GPU do to my PC???

[hreyhrey]

So I got my friends 5770 (which turns out is semi busted-black screen of death) anyways after a TON of cold booting I destroyed my HDD and was forced to get a new SSD...

Now I have my old GPU, old CPU, old ram, old mobo. All of those are pretty updated except my GPU is old but they all worked PERFECTLY before I swapped GPU's adn now HDD's!!

Ok so my question is I get RANDOM FREEZES now.

Would you guys think its a bad windows installation? The CPU is intel quad core, ram 8gb, mobo a gigabyte, SSD hdd, and gta 250.

All of those worked in synch perfectly (xcept an older hdd not ssd)

I installed it fine and it worked decently but still had some freezes but now its constantly freezing.

I used speedfan everything was in order AND I cleaned it out.

My only reasoning must be a bad windows installation right?
