I've recently upgraded my PC's CPU and Graphics Card to a Pentium 4 3.2 Ghz processor with Hyperthreading and ATI Raedon X850 AGP graphics card. After upgrading I've experienced a lot of random freezing when doing simple tasks, and when I play 3D games, it randomly crashes the first time it crashed with no BSOD and I had to restart and the second time it crashed with a BSOD with an IRQ_ something error message. I haven't needed to reformat as it hasn't given me an error when starting up with the new hardware inserted as it usually does as I took precautions with uninstalling my old graphics card drivers. However I've not uninstalled my processor drivers before inserting the new one so I'm not sure if that's what's causing the problem. I've noticed however that in the Task Manager (CTRL+ALT+DELETE) that in the performance tab it has 2 graphs for my single processor, and 2 instances of the same processor in the CPU tab on the Device Manager, I'm not sure if this is supposed to happen or not with Hyperthreading enabled, but it is odd.
Both pieces of hardware are new and there's no evidence of them being tampered with, I've inserted them properly and everything works fine except for this case of random crashing and freezing that keeps happening.
Most, if not all of the freezing happens when I use Firefox, I'm not sure if this it's just the program itself that's messing around, but it never used to randomly lock up when I was browsing the internet, Internet Explorer hasn't locked up on me as of yet though so I'm really confused as to what the problem might be and if there's even a problem in the first place...
Could anyone help me?
