    I have a pc with a 1.7 celeron cpu, 768 MB DDR Ram, cd-writer, dvd-burner, a 40 gig and 120 gig hard-drives, and a Radeon 9700 pro video card. Also, the power supply says 400 wats. I bought it as a barebone system January of last year. Haven't had any problems until a week ago. When I try to turn it on, either it won't come on at all, or it will start to boot up, but after about 3 or so seconds, it shuts off. Any ideas on what could be causing this problem. I want to try to fix this myself, currently I don't have the funds to let someone else fix it. Any help given is greatly appreciated.

    May be a problem with unstable power from the power supply.

    if you think it is the power supply, what supply would you recommend? I'm also in the market for a new tower and to upgrade the motherboard and cpu, but I dont want to spend a fortune. Any suggestions? I've checked out ebay, but I'm kind of wary.

    I suspect your CPU cooling system, since I just got through dealing with a similar problem. In which case it is possible that your computer stopped booting up when the CPU finally fried.

    Someone else installed by CPU and cooling system so I don't know what kind of thermal greese was used. I suspect the thermal greese because the CPU was sorking fine for a couple of years.

    I installed an upgraded cooling fan, and new CPU using artic silver which solved that problem.

    thanks, I'll try switching the cpu, or I'll just go ahead and upgrade with a new motherboard and faster cpu. Anyone know where I can find some at a good value. I wanted to upgrade to at least a 2.4 P4 cpu.

    I would definitely invest in your CPU cooling sysem and artic silver as well. It's better to spend your money on that than to loose the entire contents of your hard drive like I did.

    I have to agree with gotrootdude. The power supply may be faulty since its a barebone case they use the cheapest power supply they can find.

    I really doubt that the heatsink needs to be reseated. If it wasnt cooling the cpu properly the system would be warning you. No offense guys....

    You asked about a good quality power supply. This is something everyone should have! The power supply is the most important component. You certainly wouldnt want to spend $500 on your system and install a $20 400 watt power supply. If the el cheapo psu fry's, you could be outta close to that $500 dollar upgrade.

    Good names to go by is antec, enermax, fortran, and sparkle. Steer clear of allied, foxconn, and deer just to name a few. I have seen too many of these go boom!

    As the saying goes you get what you pay for.....
    Good luck!
