optiplex GX280

welll a lot of things dont know where to start... i jst bought a new (fo me atleast) pc. which of course is dell optiplex gx280. thats a big step forward fo me as i jst ditched my stoneage's compaq intel 815 supported pentium 3. first thing to know about my pc is that its second hand. m from pakistan n the only branded pcs we can get are the one which are second hand n shipped in here as junk.

now to the real story. since the day i bought it m jst not feelin rite about it. there have been more problems than i can count.... first it doesnt hav ps2 ports so i hav to resort to usb to ps2 connector which although has resolved the issue but has its own share of problems. the problem with it is that whenever i turn on my pc everythin is jst fine but when i reach the operating system n logon screen all usb ports are dead so i hav to replug my keyboard mouse n my wireless internet connection to make them work. the same thing happens when i put it on standby mode. keyboard n mouse jst die. so i hav to press the power button to shut it down n restart again. i hav searched deeply enuff for drivers formatted hard drive changed operating systems. nothing works. secondly its cpu fan is very alarming. sometimes its totally quite i mean it works but doesnt gives any sound but sometimes it jst makes noises jst like a cdrom at full speed n i can feel the vibration in my table. another issue is that it hav no space for IDE hard drive. i cant do widout it. so i removed the floppy drive put the hard drive in here. got a dual connector power n data cable. n after that i was able to make my harddisk n dvdrom work at the same time. before i changed the cables ther was no hard drive issue. but jst 10 mins after changing cables my IDE hard drive crashed (it has a SATA too) i wasnt able to acces any of my drives. i tried chkdsk but wasnt successful. so i formatted all the drives n retrieved some of my data after tryin atleast dozen of data recovery softwares. the conclusion is that m now too afraid to open the casin. n m already thinkin of gettin rid of this piece of junk. help please..............

Troubleshooting Device Conflicts with Device Manager

It really sounds like you either have incorrect drivers for your motherboard or a device conflict.

You may want to try running setup using the /p i switch at setup. This switch tells Setup not to report the existence of a Plug and Play BIOS.

i m more than 100 percent sure that its not a driver issue. i got the drivers from the dell website. exactly made fo this model. win 98 n me are out of question. why someone would want to use them. problem is with xp. service pack one n two. fresh clean installs on formatted drive along with freshly downloaded drivers. device managers doesnt give any errors at all. infact there are no errors of any kind. just the mouse n keyboard are all stuck at the log on screen same goes to my internet. i have to unplug n replug both devices at the usb ports to make them work. its simple as that.
