Please provide details about your system (CPU, motherboard, GPU and PSU). Did you check the CPU and GPU temperatures? Are you using a quality PSU? There's a sticky on troubleshooting. Did you read it?

With no discrete video card, your system uses very little power, and probably would not stress even a mediocre PSU. Unfortunately, you have one of the lower quality Foxconn boards that had problems with bad capacitors (Google "bad capacitors" for information including images).
If you like, post a budget, system uses (e.g. web surfing, gaming, spreadsheets, etc) and location (so we know what online retailers are available to you), and we will help you select the parts to build a new PC. There is a sticky thread at the top of the home build selection with a good template that you should use for this.
As a cheap alternative, you will be happy to know that you should be able to pick up a used machine able to outperform that one for <$200.
