This Guide gives advice on the following common PC Hardware issues:
Slow/juttery use, sluggish response, no graphics output, Blue screen crashes, non reading DVD rom's, non detecting HDD's, dead PC
If your PC computer is:
Slow/juttery: try upgrading your memory, this helps increase the ability of your PC to handle information simultaneously.
Sluggish/slow PC: Try upgrading your memory or it may be a failing/overheating Cpu. If you can also hear a 'clicking noise' this will be your HDD (hard drive) failing and it is highly recommended that you back up your info(if still possible) immediately and replace it.
No graphics output: This can actually be something other than the obvious. Sometimes this can be down to your modem card (if you have one) interfering with the motherboard IRQ's in which case you have a quick fix. If not it can be the graphics card, motherboard, CPU, memory or even PSU. To source the problem i normally this procedure in the following order, until it is cured; remove modem (if applicable), exchange graphics card, replace memory (or test one at a time), replace PSU (although this only accounts for around 5% of the issues its cheaper to replace), replace cpu, replace motherboard.
If you are wondering why the PSU, sometimes they 'drop' a voltage which prevents graphics even though the computer sounds fine.
Random blue screen crashes: Hard to offer firm advice on this but often it is a hardware compatibility fault and from personal experience sometimes the hard drive or memory.
DVD rom does not read DVDR or DVDRW:some early DVD roms simply do not read these discs, a replacement DVD rom is the easiest solution.
HDD sounds as though it is working fine but the system does not detect it or does so incorrectly: Normally this is the controller board underneath the HDD, these can be replaced for like to like replacements (i even sell some) but it has to be a perfect match and does not work everytime. I would only recomend this for anyone who needs to retrive important information, if you can do without it just replacing the HDD is simplest.
No power at all/dead
Normally this is the PSU but dont forget to check the power cable too! if it is neither of these check your power button cable and motherboard.
