HP Compaq 6300 (Microtower)

Everywhere I go I can't get help and I'm starting to get frustrated.

PC "turns on" but doesn't even get to BIOS. Monitor stays blank, and fans turn to max speeds.

I've reset CMOS like 5-7 times in a row just now and it didn't help a bit. 

The weird part is that sometimes it works, and sometimes it does this. (More often that it doesn't work)

I'm kinda lost at this point. I've been troubleshooting for a while now and I really don't understand why it's behaving like this.

Intermittent problems like this one are nearly impossible to troubleshoot successfully -- so you have to take drastic steps.


Boot failures are nearly always due to filesystem corruption -- of which the two most likely causes are sudden shutdowns and drive failure.  If your PC is not shutting down, the second is the most likely cause.


Drives don't suddenly fail totally one day, but they fail over time -- and the failures get more frequent as time goes on.  If the reboot issues are getting more frequent, that is a sign that the drive is failing.


If your PC is new enough to support UEFI, you can use these steps to test the hard drive:

If not, to check the drive you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu
3) Press the Function key for testing the hard drive (usually F2) and let it run.


However, if you can't get the PC to come up even enough to run the diagnostics, then there is nothing that you can personally due to figure out why it is failing.


If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
