Hi all, Last year I bought a circa 2007 vintage HP Lenvo dual core. I was enjoying it for about 5 months when one evening it just halted ... as in, powered off in the middle of everything. Now I like this machine a lot, despite it's short time in my company. I first suspected the power supply, but that powers up just fine ... if much can be read into that. I put another hard drive in, took out the processor and cleaned the contacts with isopropyl alchohol etc ... The bottom line is, when I switch it on the monitor displays 'power save' mode, and then repeatedly goes in an out of it. What I mean by 'out' is that the screen stays black, but the green light comes on ... and then turns orange again. The USB ports still recognise stuff at the front (for a split second), the CD seeks, the drive light comes on ... Having read various threads I went and had a look at the motherboard, and a few of the components look like the heads have 'domed' a little ... but it's hard to tell if they were like that already. I really need a dual core and most of the stuff for sale 2nd. hand comes with 1 gig of Ram which is below what I need (this machine has 3). I can't afford to buy new. I guess unless there's something really indicative in what I've posted I'll be giving up on it. As I said, I do like the machine and thought I would run it by you guys in case there's something I'm missing. Thanks in advance. Tony.
