Hi, Working on a computer for some friends of mine and have run into an issue. I just did a fresh install of XP and even during the install as well as during updates the computer seems to go into sleep mode and cannot be brought back without forcing it to shut down via holding power button in for a few seconds or unplugging it. I have sleep disabled in windows and it appears to happen for no apparent reason. The screen goes blank and the power light turns amber no matter whats going on. Hard drive remains running as do all fans. The four LEDs at the rear of the PC all go out. I noticed many of the aluminum electrolytic caps around the CPU are buldged and am planning to replace them, however I was to be sure the caps would cause this kind of problem before I go through the trouble. Has anyone had a dell like this act this way due to caps? I'd like to get this thing working smoothly for them as money is tight and its mainly used as a word processor. Thanks, Chris J.
