My PC has been very slow and glitchy for a while now. I used to play Fallout 3 at 60FPS and all my other games at good framerates. I haven't played Fallout lately cuz it always freezes my PC now and if it works, it'll work for less than 2 min. at like 15FPS. I can't watch HD content anymore because it glitches when it didn't used to.
I have an Athlon 64 X2 5000+ BE. I check it out on CPU-Z and the HT Link is at 200MHz. I remember seeing 2000MHz back when it was working fine. I went to BIOS and changed it to 2000MHz but when I boot up and check, CPU-Z says its at 1000MHz. I know 2000MHz is default because all the websites say the HT is at 2000MHz. I tried Fallout after the change and it played nicely for like 1 min then froze up my PC
Could this be my CPU's problem? What else could be the problem?
