Hey guys!
Yesterday I received a couple of parts to upgrade my desktop computer... the main reason im upgrading is because I need better graphics and video encoding speeds.
My computer is an HP Pavillion a6720y... http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01643511&tmp_task=prodinfoCategory&cc=us&dlc=en&lc=en&product=3856272#N35
Specs: Phenom X4 9550, 6GB RAM, 640 GB Hard Drive, 300W Power Supply
The motherboard has plenty of space for a nice graphics card... But I knew I would need a better PSU in order to get a decent graphics card running properly. So these are the parts I bought:
HD 6770 Video Card - 1GB, GDDR5, PCI-Express 2.1 (x16)... http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=869628&SRCCODE=WEBLET03SHIP&cm_mmc=Email-_-WebletMain-_-WEBLET03SHIP-_-03ship
Apevia ATX-WA750W Warlock 750-Watt ATX Power Supply... http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=3756955&SRCCODE=WEBLET03SHIP&cm_mmc=Email-_-WebletMain-_-WEBLET03SHIP-_-03ship
This is where it gets weird.. Since I usually work in steps, I decided to get the PSU working first so I could then work with the graphics.
I replaced the PSU, connected all the cables how they suppose to be... I noticed there wasn't a 4 pin molex in my motherboard cpu but realized it wasn't necessary since it had a 20+4 cable instead of the stock 20 pin..
When I turned it on... the power light goes on, fans start spinning, dvd drive works... opens and closes, cpu fans spin for about 10 seconds or so... then stops. and no monitor signal or post... I also don't get any beeps aswell.
Assuming it could be the monitor, tried on another monitor, didn't work either.
So I switched back to the original PSU and that one doesn't work anymore... The power button just blinks and goes off again.
So I tried the Warlock 750W psu on another HP m8200n machine, and it doesn't work either. Although that machine does boot and post when I use the original PSU..
This is the funny part, when I tried using the m8200n's PSU on the a6720y, it does the same as the original PSU, just blinks and nothing... no post.
As of now, there is no way I can get post on my original machine!
Things I've tried":
1) replacing memory
2) clearing CMOS
3) switching back and forth between original and new parts (changing cables)
4) tried the PSU on two diff units - it turns on and seems to be working, but no POST.
5) cleaning case
6) turning the desktop on with no memory, hd, or optical drives - no post.
7) holding power button on with power cable disconnected.
I have no more clues of what to do, any help greatly appreciated
Thank you!
