Re: Dell 745.....Here we go again!

Where I work we have 120 OptiPlex GX620 machines (mercifully almost all have been ok for 5 years), but of the 10 or so OptiPlex 745 workstations, 5 have now died with bad caps on the motherboard. The symptoms were hard lockups showing a full screen of the same colour (e.g. orange, white, green, grey). We use onboard gfx. Three failed in warranty, and now another two. Dell are refusing to support them as they're not on their list of bad cap machines. They were bought in May 2007, so they would be inside a discretionary 5 year warranty as mentioned...
