Persario computers 7000 HDD problem , won't boot , light turns orange !!

Bought 9/2000 runs win98 se

Started a week ago won't boot ( Green lights steady ) until trying many times,.
Then after opening the cpu couldn't find any thing loose!
After disconnecting and connecting power plug from the HDd the PC don't boot and the hdd light is steady orange ! Does that means the hdd is not GOOD any more?!
Is there any trick i can do!um if nothing on displays on the screen at all no workds or anything its the moniter or video card try a different moniter or video card and see if that helpsI don't think it's the monitor cuz the PC should boot w/ o it . Right?! well the computer is probably booting the video card or moniter just isnt working so you cant see it if it was the hard drive there still would be the bios ANS stuffYa i just had this problem it could be a few things.
First try the monitor cables and monitor
Second try the ram re seat or switch out
Third video card
Forth cpu
finally your mobo
The mobo is what happened to mine but nothing unexpected with the emachine.How i test the CPU ! What is mobo!!! How i test all that to know what 's wrong? before i buy new PC.
ok first try to get a different moniter/cable and try if it still doesnt work try a different video cardMOBO is your mother board and as for testing these 2 mobo and cpu you just need to switch them out. but based on what you have posted here i probably wouldn't try any of that unless you are comfortable with pulling everything apart.i did some reading it could also be your power supply.Other than buying these parts one at a time and installing them i haven't found anything that can help you. I f i was you i would buy a new computer yours is a bit out of date anyways is it not. Any way sorry i couldn't help a bit more good luck.no all you need is another moniter or a video card you can get another video card cheap and another moniter pretty cheap too

Then it gave his error " EMM386 has detected error #n9 in an application at memeory address 00B8:1628.TO MINIMIZE THE CHANCE OF DATA LOSS. EMM386 HAS HALTED UR PC .

AND SOME TIMES EMM386 NOT INSTALLED - UNABLE TO SET PAGE FRAME BASE ADDRESS.
THEN WHEN I PRESS ANY KEY , IT READS IT AND SAY
EMM386 SUCCESSFULLY INSTALLED
EXPANDED MEM SERVICE UNAVILABLE

TOTAL UPPER MEM AVAILABLE 74KB
LARGEST UPPER MEM BLOCK 42 KB
UPPER MEM STARTING ADDRESS D000 H

EMM386 ACTIVE

WHAT ALL THAT MEANS ?? ISIT THE V CARD OR NOT OR THE NEW V CARD IS NOT COMPATABLE OR WHAT ?? OR IT MY MEMORY THATS MAKING ALL THE PROBLEMS FROM THE BEGGINING ??

should i but back my old v card or what ??One more thing, when i am able to log on on safe mode the i run CMD THEN WRITE mem
