error help. please

Ok I am recieving error messages, 1003,1000,29,17,20,256,615,1020,62,63,1517,529,680, and I recieve different ones every day in my event/log viewer in the administrative tools event viewer window. Ok this is after I have already 1.Been given a new hd from dell, 2. I have a new oem windows xp sp2 rom from dell and I have gone over the instalation process with a dell tech. I am extremly mad, I called for help and they want me to pay for help I refuse to pay when these problems have probably been with my system from day one. And how do I know this well when I ordered my dell comp I requested no floppy disk with it later to find it was preconfigured with a floppy disk in it despite not having one on my system. 2. The printer software for my printer ordered at the same time in previous virus scans the files dealing with my printer have a _unknown after the file names for my printer. 3. two weeks or so after having my computer my first hard drive was determined by a dell tech to have failed out. Ok at this point I wanted a refund but was told I could not recieve one, and was assured that a dell tech and a new hard drive would arrive at my house. Ok The tech they sent removed the bad Hd put in the new one and while my windows was loading jumped in his car and left previous to this he did give me brief instructions on how to install the device drivers etc... but I saw this as very unproffesional on his part he should of stayed tell everything was finished and made sure no errors where on my comp. Despite this I am a novice computer user and really had never even heard of an event viewer before to know if problems were occuring with my computer. ok fastforward once again after recentley seeing both my dvd rom drives dissapear I called dell and told them of the error messages and they decided to send me a new hd and a new windows oem dvd rom. ok I installed these and am still getting these errors. so I called once again for help and they said I have to pay why? with a fresh system as in new hd and new operating cd rom after installing these why should there be any problems at all with my computer? and I recieved these parts last night. and right after installing my windows I checked the log viewer and had errors? then after installing my drivers I had further errors? so I decided to come on the www.dell.com to get help and was told that ok I would finally be helped and what I needed to do was 1. restart my computer. 2. tap the f2 key. 3. once at the magical system setup screen to press the caps, num and scroll lock keys and then to hit the alt and E keys at the same time. I should hear a beep and I did then hit the esc key and enter to save the changes and to reboot my computer. This was soupposed to fix all my problems. Well It did nothing i checked the log 4 more times and all the errors remained there, I even repeated the process 3 more times nothing. Ok so finally I just manually cleared the logs from within the event viewer and rebotted my comp only to recieve more and different errors this time. OK I really am mad now, all my windows updates are up to date the 34 or so of them. The dell diagnostics tool says everything is fine. And on top of that the tool that scans my computer on the dell website says everything is ok and up to date. So I really have no idea what is wrong with my comp, I have not installed any other software on my computer and I just think this is horrible dell will not help me but they will send out new hd and software to me does not make sense at all. I have tried to google my problems and look them up on microsofts web site with no help or solutions at all. I even called microsoft and they told me dell is responsible for helping me with this problem. ok but dell tells me I have to pay 100 dollars or some crazy amount, when microsoft charges half of that on their website? I was also led through a debug process in the dos menue evertything was fine so I'm lost someone if you can help please do I bought my comp for around 1300 dollars in 2004 thinking this demension 3000 with the 80gb hd, and the 16x dvd/cd rom drives and pentium 4 processor was going to be a good school/internet computer and the extended dell soupport and the all in one printer was a very good deal at the time boy was i wrong dell from what I have experienced is truley a bad company and does not like to provide help and when they do it is next to impossible to understand the foreign service rep tryin to help you. someone please help me please I beg you. and sorry about my eeee post but after writing a long message like this I was told I did not log in, ok then why was I even allowed to type a message anyways please help me please.
