Screen Freezing after 1 - 2 hours

[Pinickitty]

For the past two weeks the screen has frozen after about 2 hours with the
only option available being a hard reboot.

If I am at the PC when this happens the mouse will get stuck at the last
point on the screen and the keyboard stops responding (i.e. I can no longer
toggle capslock for example) and if I am not at the PC the monitor goes to
sleep and tells me there is no input from the PC. I have recently moved
house so my initial thought was that maybe something had become unseated so
have taken everything out of the mainboard and reseated evrything without
any success. The only addition I have made to my PC recently is the adding a
netgear WG111T wireless dongle.

PC specs are as follows

ASUS P4C800 e Deluxe
P4 3.0Ghz
2.0GB Ram (4 * 512 interlaced)
GFX 6800GT

Any suggestions would be most welcome

Many thanks

Nick

Do you have any noticeable hesitations when you do a cold boot? Do your boot
screens look normal?

I am thinking there's a hardware problem somewhere although without some
troubleshooting it's hard to tell.

The cheapest thing to do which is always a good idea anyhow with a new
system or motherboard is to change the CMOS battery to a known brand name.
$3.00 at Radio Shack.

Your graphics card could be dying? From problems I had with my mouse and
programs years ago I'm convinced there's a strong connection between mouse
and video card. I'd be working fine for who knows how long and suddenly the
mouse wouldn't move or took a lot of tricks which was useless for doing
anything worthwhile anyhow. That was back in the 1990s and a new video card
was the final fix that worked.

If there was a problem similar to yours with your particular series of mobos
I imagine you'd know about it? I had one once that everyone who had it had
big problems because the wiring or whatever connections in it were bad and
the RAM often failed for no obvious reason.

Do you have an old or under rated power supply? This is the first thing I
would try switching out. Your Netgear thing may not use many watts (I don't
know) but it could have put your particular PSU over the line or the PSU
could be failing.

Could be something simple like too much of a heat buildup after awhile or
too much dust and dirt inside.
