556745 2007-06-06 11:20:00 Over the past few weeks my PC has been doing some strange things .

Firstly, the screen and mouse freezes . Then the screen goes black and blank . A second or two later the screen comes back to life .

Software or virus’ have been discounted as I’ve put a new hard drive in the PC since this started and have a clean install of XP (with SP2) and it still does it!

I've removed and reinstalled all hardware to ensure it's not being caused by a dodgy contact, but no luck . Neither with pulling all cables and swapping a few around .

Sometimes a freeze will happen immediately after start up, hence heat is not the issue . Other times I’ll work for an hour before it happens . At other times the freezing happens almost back to back and usually ends in a system lock up requiring a reboot . When this happens the black screens after the BIOS screens have random letters and symbols over it . This makes me think it’s a video card issue, but alternately a CMOS battery going flat springs to mind .

Any ideas please… .

Could you post some more details of your hardware .
E . g
Motherboard make and model
CPU type and speed
Graphics card
(basically all the core bits)

nah..............never seen a flat battery do anything like that

i'd pick a bad video card or video system if onboard......and yep maybe it's bad capacitors too...easy to check that...

The "blackouts" occurred immediately after loading XP and even before I put the nVidia drivers on, hence video card drivers can't be at fault .

Leaky capacitors is a new one for me . . . .

drcspy said bad card, not bad driver for card .

556750 2007-06-09 07:13:00 I've checked all the capacotors on the mobo and vidoe cards and have found no visible sign of leakage or bulging. How else can the capacitors be checked?

Next step is a new/different video card and I'll see what happens...

Not faulty drivers. Not faulty capacitors.
Try another graphics card.
