A guy at work ( a financial market analyst) had a pretty powerful desktop PC when I started at work in March:
3GHz P4
2GB Ram
standard 100Gb hdd
Matrox Perellia 64MB card ( strange digital port on the back - not unlike a scsi port - which had a cable feeding two vga leads {ie a "Y" shaped cable})
2 *17" TFT's
Windows XP SP2
Office XP / now upgraded to 2003
EcoWin - (analytical graph program which gets data feeds from Bloomberg / Reuters via MS Powerpoint)
Anyway this PC was about two months old when I started, and it used to have terrible flicker problems , specifically as if the card was taking wayyyyyyy too long to update the TFT. No scrolling was smooth as it should be.
I immediately thought it could either be a motherboard ( PCI graphics port) driver or a graphics card driver itself problem. Initially updated the grahics card driver itself manually through Matrox download, restarted and PC was ok for a few days.
Same problem re-occurs again - and no video driver update had happened overnight - so I updated the mobo drivers. This then settled the problem for a couple of weeks
We get another call, this time My boss goes up, and he thinks he has solved it with another download from Matrox - this lasts a day!!!
Our reckoning is that it cant possibly be the TFT's as no matter how many pc driver upgrades we do if the TFT had a problem then it would always be there, but it definitely goes away for a time and then comes back with no connection between events that we can locate.
Two weeks ago, I presented this guy with a completely new PC, even more powerful ( as it was new and he was struggling anyway - with 20 odd emails open, several graphs, a couple of presentations, you name it hahaha) but this time I recommended one of the medium range Nvidia Quadro cards (we have limited choice due to PCI connector in the HP PC model the company have standardised on)
This PC lasted two weeks and the same problem has arisen. I know this time we should probably swap the TFT's anyway, even though I cant see a logical reason why.
Anyone got any ideas as to what else could be causing problems?
(We also use UPS's on every machine with internal batteries to avoid surges / spikes causing problems - so it cant even be that killing cards etc)
Any assitance would be greatfully accepted
