I bought a dell e5420 . It turns on but cursoe comes '-' and nothing after that. I bought it like that. I tried installing windows 7 and xp but it installs for a bit but then error comes saying that there is error on hard drive. But when booted from cd and run diagnostics no error comes.
Also amazingly.I opened it and the hard drive inside is 250gb and in dos it is showing hard drive of 30 mb. It has i5 process 4gb ram and I think at one one time it has windows 7 on it as it says on the label.
I check all the cables and it is connected inside, the hdd.
