    It's a desktop with Windows 7.

    Turn the power on and the fans start going but nothing appears on the monitor. I tried another monitor and cable but still nothing, so something must be wrong with the computer itself. Can anyone help me figure out what is wrong with it?

    First of all, post the exact specs of the system you are working on; ie make and model of mb, brand and wattage of pw supply, etc, etc. If this is a big box system ie dell, hp, whatever, then post the exact make and model.

    Next is this a new build or any existing system? Did it ever work? Have you installed any new hardware and or software?

    Lenovo 3000 H Series. That's what it says on the case, it's a store bought desktop computer, and it belongs to my landlord, I never use it. It has always worked before, he doesn't have any clue why it isn't working now. He is not tech savvy, so it hasn't been upgraded or anything, it's still stock.

    *EDIT*

    Took the case cover off, PSU is a LiteOn PS-5281-7VR. Sticker on the case says it has a Intel Pentium Dual Core Processor E2220, 3GB DDR2, Intel GMA 3100.

    There's no indication of the wattage on the PSU, and the graphics is onboard.

    OK, start with some basic troubleshooting;
    1 Reseat the atx and aux pw connectors; ie pull them OFF then reinstall. Check to see if it will post.
    2 If not, then swap in a known working pw supply to test. Note you do not have to fully install the test unit. Just connect the atx and aux pw connectors. Now push the pw button and see if the board will post.
    3 If not, then with the system OFF pull the pw connectors from ALL drives; both hd and optical.
    4 Disconnect any usb device; ie scanner, printer, hub, etc
    5 Remove any add-in cards like sound, nic, etc [if used] since you have onboard video, there is no video card.
    6 Now pw ON and see if it will post. If it does, then add devices one at a time until you find the failed device. If it does not post, then you will need to swap parts with known good units, ie mb, cpu, ram, etc.

    The pw supply is the quickest and easiest to test so I would start with a known good pw supply and go from there.

    first port of call would be cleaning and reseating the RAM, had the same issue when my mobo wouldnt post...no beebs at all so that was no help, if the fans spin up then there is power getting to your mobo...but yeh lots to test for on a prob like this as stated above...i would start with the ram tho...most common issue for not posting
