These have started since two things I have recently done to the PC
1) I installed a external HD in my USB port, I tried it in the USB2 port but it said it couldn't find any USB2 devices? in none of the ports I tried, the 4th USB2 port has my printer and it works fine, I moved it to a normal USB1 port and the HD worked ok although I started getting BSOD's so have taken the HD off the machine and still getting them.
2) My Norton Internet Security ran out so bought another copy (2004 version but never used and a genuine copy) I installed it and ran all the updates etc, it works fine as a firewall and AV but the BSOD's have started as well since installed this software.
The two types I have had are as follows:
1st type - Stop:0x00007E (0x0000005,0x00003C00,0x0F7CDA348,0xF7CDA844)
2nd type - Stop 0x00000050 win32K.sys error - Page_fault-in_nonpaged_area
My machine (which up till then has performed great) is a Athlon 2000 and has 1GB of memory
The only other thing I could put my finger on was that it is periodically starting to freeze, not often but getting more and more and I have noticed that the fan has stopped spinning on my Graphics Card so presumed the freezing was overheating?
I run AV regualry and nothing turns up, I also run Ewido, Spybot and Ad Aware as well as Trojan Hunter and it only finds the useally spyware cookies, no trojans etc.
Any suggestions as to what may be causing these?
I think the external HD was probaley a coincidence as it happened at the same time I installed Norton and has made no differance since I unplugged it.
Any assistance greatly accepted thanks
