For the last couple of weeks my PC has been playing up when I'm trying to install different software.
Athlon 64 3000 CPU
2 x 512 DDR400 PC3200 Ram
GF6600 GT
80 GIG SATA
80 GIG IDE
I have two HDD's ones a IDE drive and the other is a SATA.
I tried to install SP2 on the SATA drive that I was using as my main drive and the problem was it would install SP2 but when It rebooted it would crash and keep on rebooting and kept going in a endless cycle.
I started in safe mode and saw the blue screen that says:
stop: 0x0000008E (0xC0000005, 0x80614A10, 0xBA31FB68, 0x00000000)
Beginning dump of psychical memory.
Physical dump complete.
I then decided to do a fresh install of XP Pro with service pack 2 and all went well, then when I tried to install Zone alarm the same thing happened again, blue screen again..!!

So I decided to use the IDE drive as my main drive and went to upgrade to SP2 on the IDE and the same problem appeared, so I had to keep SP1 but it allowed me to install Zone alarm without any problems.
I went and bought a New MOBO today as my other one blew up, so I've tried a fresh install again on the SATA but the same thing happens with Zone alarm although SP2 went on with no problems at all this time.
Basically Ive got one SATA drive that I can't load Zone alarm onto and a IDE drive that wont allow me to upgrade to SP2.
Both get the same blue screen of death message, yet I've tried with both memory sticks in and out and the same thing happens, but I can play games with no crashes or freezing up at all.
I've looked on MS site but to be honest I don't understand half of what its talking about, and I don't really want to spend out on another gig of ram if the memory isn't the problem.
Any advice would be much appreciated.
