Hi all,
just recently after a full format when installing games i get crc errors and the game cant install,
I have posted on here with the question before and i was told to disable Ultra Dma Mode on my drives and i did.
But now even with pio mode enabled i get crc errors on some game installs and i also get crc errors when trying to unzip large files?
Surely this can only be 1 of 2 things either my motherboard is going or my hdd.

I have replaced all the ide cbles in the pc just incase it was a dodgey connection, but the problem still occures.
Also during loading of games i will sometimes get textures not loaded or some files missing.

I also sometimes get errors like opera (My browser) has to shut down, occasional blue screens and recently windows explorer has occured a serious error and must shut down, to which i have to reboot?

I have checked for any virus etc etc i have pc cillin and zone alarm as my firewall.

My pc seems to run fine sometimes and then badly on other days? Im at a loss as to what it can be? Plz help

Cheers for ur replies in advance
