AMD Athlon 1900+
512 ram ddr
Recently my pc kept resetting at random intervals. And now It wont load windows at all without resetting. It will do all the usual start up sequence, detects drives, ram, etc and thats all fine but when the windows loading logo appears it re starts,(XP PRO) However it will start and run fine when I set the CPU to 1200mhz rather than 1600mhz in the bios. Is my CPU or mobo Fried ??? I have tried the following, with no luck.
Bought new heatsink and fan (with compound)
Tried starting without unnecessary components ( no sound card, only 256 ram, no other pci's etc. )
Even when cold it wont start.
