Joomla internal server error

[karand]

Hello,
I wrote back few days back also. My site: http://Kdesi.x10.mx .That time i just had problems installing joomla extentions and it was fixed. But currently the problem is much severe, even though the extentions get installed 30% of the times, but this time whole site is having the same "internal server error problem"
Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, no-reply@x10hosting.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.


Sometimes though it runs smoothly but then when it starts having this problem, it really irritate the hell out of me :-( And ya i also have phpbb3 forum, and its working well even though joomla is totally down from past 15 mins but since both are intergrated can't login to phpbb3 also. Please help me out
Thanks in advance.

No reply yet :-( anyway this happened like at the start of evening yesterday n in morning it was ok. i guess my site is down like 70% of the times. Lot of errors including "500 internal server error", then suddenly databases disappear n it returns database error, n from past 20 mins again the site is down "The page you are looking for is temporarily unavailable.
Please try again later. " i really dunno whats the problem here. The same site was working fine on my older server, but now its not working even 30% of times. What am i doing wrong??
