Hi, I need some help as to figuring out if I need to buy new CPU, Mobo, power supply.

Today while I was playing COD4, it froze.. and i had a high pitch sound in my headphones. I turned off my computer and it wouldn't start.. it would do the ram check (it gave it an ok) it got to the windows xp logo, froze. I turned it off and decided I would put in my old video card (8600GTS) because possibly I fried my new 9800GTX (I don't think I did). Same problem, it would freeze. It would freeze at random places, I would get to "last know config" or POST error has occued prompt and the countdown would freeze at 15sec, 11secand 8sec on multiple times. A few times it wouldn't even starting checking for my hard drives. I got in to safe mode, but it froze when a command prompt popped up. I couldn't get in to the BIOS.. so I reset the jumper... it worked then it froze, tried it again (resetting the jumper) froze. I took out the sound card, disconnected the HD's, took out my ram all expect for the one.. switched them around... same thing, locked up. I hooked up a 250W PS (regular is 600w) and it still locked up, I would figure even if its not enough watts it wouldn't freeze at the BIOS or doing the IDE Master channel listing. I'm puzzled as to whats wrong, I have a Gigabyte GA-M57SLI-S4 for my mobo. Would it be a dying CPU? heats up then gets to hot and locks up? borked PSU? borked mobo? Please help, I don't want to buy a new PSU/CPU/MOBO and figure out it still doesn't work or have to buy something needlessly.

Sounds like a memory stick or the processor went bad. You can download memtest86 to a CD or floppy and run it for a while to test the memory. If the processor cache is bad it should show that too. If the central processor is bad it should show a machine check exception in most cases.

I downloaded memtest86, put it on a floppy.. actually my psu didn't seem to have a floppy power connector so I had to connect that 250w. I got to the boot menu, when boot from floppy, said it was starting but then it froze. I'm not sure if its the ram, I have 2 5400 OCZ and 2 6400 OCZ, i've just one 5400 in, same thing still happened. I put in a 6400, same thing still happened.
