My machine was starting to act up, having trouble booting and geting random reboots, I thought it was malware so i did a compleat system REFORMAT. While installing windows I got a random reboot during the install then after reinstalling again (I never got the welcome screen to come up when I booted, it made me SUSPICIOUS) I am trying to install windows updates and I keep getting an error from update.exe

The instruction at "0z00f59c62" referenced memory at "0x60ffe30". The memory could not be "read". I will get this many times and the refrenced memory is allways the same ADDRESS. the adress is also the same after rebooting and trying again.

So my question is, I know I have hosed hardware. What do I need to replace? 0x6 is way out of 1GB mapping area (assuming ram starts at 0) according to device manager that chunk belongs to PCI bus.To me it sounds like a memory problem.

TRY pulling the RAM out and after clearing any dust in the area put the RAM back in...sometimes you can get dust to make bad connections across the contacts or it can even just be that the RAM is not seated all the way.

If this dosen't work than try changing out the RAM.

You can also DLoad and RUN Memtest on that RAM...let it run for a few hours...I would first try the Power supply. It is the least expensive piece of hardware.
I have seent this happen many times before & about 95% it was the P/S. the other 5% was the system board.
