Computer crashes, VGA no signal while gaming.

Batpool · Jun 4, 2014

I've had my computer for about a year and a half, absolutely no problems with it, today it started crashing with an FPS drop when I was trying to help a friend on Star Trek Online, didn't think anything about it. I've tried playing every game I own on PC, it crashes in minutes. The computer shuts off and I get a VGA no signal when i try to reboot unless I some how remove all power from the computer.

What power supply do you have? My guess would be your PSU is dying but don't have enough info right now.

It's a HEC-850ts

A couple of generic steps you can try:
- Reset the CMOS http://www.spotht.com/2010/02/reset-bios-clear-cmos.html
- Try playing a game with only a single graphics card, try the card in both pcie slots.
- Make sure that your graphics cards are firmly seated in the pcie slots, make sure the power connections are completely plugged in.

numanator :

Other than that, I have a warranty on the computer that I bought from TigerDirect, should i ship it back? Or is it the PSU? would a PSU problem cause a no signal even when I've turned it back on?

numanator · Jun 4, 2014

The suspects so far are the PSU, one of the graphics cards or motherboard. Also, did you try updating your graphics drivers? Its kinda a long shot but worth a try.

It might be easier to ship it back for warranty assuming the shipping isn't super expensive.

numanator :

I tried reinstalling drivers, uninstalled the current AMD stuff, windows took over, then during the install computer still crashes, I assume it's not the drivers then?

numanator · Jun 4, 2014

Yeah probably not the drivers, did you try the system with one graphics card? If it runs fine on one card but not 2 then it is probably a PSU issue (not being able to supply enough power for both cards). Also, HEC is a bottom tier PSU supplier, their stuff is mediocre quality- one of the reasons I suspect it may be a problem but it may not be.

numanator :

It crashes on both. I thought so, if the squaretrade warranty claim is approved they'll fix it then, if it's not, I'll buy my own PSU, maybe a GFX card upgrade while I'm at it.

Yeah, I am kind of stumped. Sorry I couldn't be more help.
