hi guys,

sorry to bother u . but the problem is not rectified. the problem is that pix boots properly. then comes to user mode. no probs. but after few minutes it stops responding . and some timeit reboots automatically. i changed the ram Power supply . still its same . what i can suspect is may be CPU problem. can anyone help me or recomend which CPU to buy and replace. i opened the box and it has interl pentium MMX cpu.Socket 7.

has anyone exprienced changing the CPU ?

i need advice which CPU to buy .

thanks in advance



Re: pix 515 problem

I had a similar issue on a costumer sites.

The PIX overheated because it was not stacked properly. It might sounds weired, I was the 4th one working on that issue and they did change the memory, Power supply without any lucks.
